TCA Peels

What exactly is a TCA peel?

TCA, which stands for trichloroacetic acid is one of the most commonly used, most studied and tested acid peels in dermatology. TCA is a medium depth peel which has been used with excellent results for over 130 years. Considered the true anti-aging peel, this peel stimulates the production of collagen, glycosaminoglycans and elastin fibers. Wound healing by TCA leads to deposition of collagen, glycosaminoglycans and elastin fibers in the first few weeks. After that, dermal connective tissue remodeling takes over which may continue for several months. TCA’s superiority comes from its versatility. It can be applied in a single layer as a superficial peel, or it can be layered to deepen penetration. Safety dictates that more layers of a lower % is always the best method. TCA is well tolerated in all skin tones and types with proper preparation for darker* types. It is highly effective for treating hyperpigmentation, wrinkles, fine lines, rough skin, photo damage, flat warts, skin laxity, acne and scarring. Between 6-8 treatments will be administered in bi-weekly/monthly increments. TCA will improve color, freshness, texture, skin tone, and fine wrinkles. It will also improve superficial discoloration, such as age spots. It may improve blotches and can sometimes improve dark circles under your eyes. TCA is a natural second step when other acids stop producing benefits. It is also the first suggestion dermatologists recommend to you to treat cystic acne issues.

Considered the "gold standard" of all acids milder than phenol, TCA peels are commonly used now due to their excellent reliability and predictability.

TCA can be easily adjusted to any depth needed to address common skin issues and imperfections. For example, someone requiring only minor epidermal improvement, a single application of 10%-15% would be effective. In contrast, if the issue is deeper in the dermis, a stronger solution or more layers can be applied to reach the issue.

I must emphasize that the number of coats, and or the volume of solution will increase the depth of the peel. The percentage concentration of TCA does not make the peel move deeper. Instead, it is the layers of solution or volume of solution that affects the degree of penetration.

How does TCA work?

TCA's mechanism if action differs from regular hydroxy acids that just dissolve bonds. Trichloroacetic acid coagulates the dermal and epidermal proteins in the skin, then "shuts down". So, the more solution that is applied, the deeper the acid will penetrate as it seeks protein to neutralize itself. If you apply many layers, TCA will continue to penetrate deeper into the skin. Applying a heavy amount of solution (I.e., face is too wet), the acid will continue to penetrate into the skin until it can neutralize all of the acid. This is why the application should be cautious so that an excessive amount of acid is not applied at any one time.

The TCA peels performed at Regenesis Medical Spa are certified - pH Guaranteed - % Guaranteed - Have Cool Action and are used in Spas and Dermatologist's Our TCA peels are professional treatments costing up to hundreds of dollars per treatment. If you are dealing with acne, pigmentation issues, rough skin texture, wrinkles, scars or just want to look refreshed and amazing, start peeling away the years of neglect now.

TCA Peel Benefits

A wide variety of chemical peels are available today for use in office. Each acid can treat more than one type of skin issue, but each chemical peel is commonly used for one particular reason. Considered the "gold standard" of all acids milder than phenol, TCA peels are commonly used now due to their excellent reliability and predictability. TCA can treat every Fitzpatrick skin type, issue and coloration. It can be used superficially in very mild percentages (10%-20%), and also for medium depth peels (up to 35% *Office only). It can be also used in combination with other acids such as Jessners or applied alone.

TCA is a highly regarded acid and is perfect for treating the following common issues:

•Blemishes •Skin Tone Irregularities • Skin Texture Issues •Age Spots - hyperpigmentation - epidermal and some dermal melasma •Fine Wrinkles •Scarring and Acne Scars: icepick, rolling

TCA peel is a great acid to use when treating scars. As you break down the scar tissues and stimulate the growth of replacement tissues. The TCA cross is technique is used to treat acne scarring. You can move things along even faster by incorporating a Copper Peptide into your revision regimen.

All skin types can benefit from a TCA peel, but patients which are prone to post-inflammatory hyper-pigmentation, or have a naturally darker skin tone, will require special pre-treatment using a melanin inhibitor to prevent and avoid any unintentional color changes in the skin. These are generally Fitzpatrick IV, V, and VI, but any type could potentially have an issue.

Trichloroacetic (TCA) Acid Peel

Free Acid Concentrations of7%, 13%, 20% and or 30% are available at Regenesis Medical Spa. We offer a professional grade "cool-action" (7, 13 and 20) TCA peel with an unbuffered pH of 1.3. TCA is the peel that all other peels are compared to. We find it is easy to use, and very predictable. Most dermatologists prefer to use TCA over other acids due to its effectiveness and dependability. If you are searching for long-lasting, dramatic changes in your skin, a TCA peel is the correct choice for you.

*Pretreat with Fade Bright for 2 weeks minimum.

In treating ethnic skin (Fitzpatrick levels III-VI), I recommend pretreating with a melanin inhibitor or a hydroquinone containing product for a period of 2-3 weeks prior to undergoing your peel. Studies have shown that TCA can be safely used in darker skin types. The safe use of TCA requires longer preconditioning of the skin, a milder strength of acid and strategies used to avoid the development of PIH (Post inflammatory hyperpigmentation).

Preconditioning includes topical agents such as melanin reducers, retinoids, or hydroxy acids that will thin the stratum corneum and minimize the production of melanin. This accelerates the penetration of the acid into the skin and increases the speed of wound healing - all of which reduce the risk of PIH.

In a deeper peel (20% or several layers of a 13%) PIH can develop when the pink stage of healing starts to fade. Sunscreens, heat avoidance, steroid creams and melanin inhibitors can help to reverse this quickly. After 2 weeks, a non-inflammatory type of acid peel such as Salicylic Acid may be used to help treat the pigmentation.

You can choose from one of the four available percentages:

Level 0 TCA 7% (1.3pH) * Preferred for those clients with extreme skin sensitivity. Great for treating crow feet and loose eye hoods.

Level 1 TCA 13% (1.3pH) * Perfect for beginning peelers who desire more flaking than achieved by hydroxy acids. **Considered the best choice for ethnic skin.

Level 2 TCA 20% (1.3pH) * This peel is suitable for those clients who have been consistently undergone application of 4-5 layers of the 13% and who are looking for more aggressive peel. Recommend working up in layers with extreme caution. *This is the maximum strength recommended for darker tones on body requiring a melanin inhibitor prep 2-3+ weeks.

Level 3 TCA 30% (1.3pH) * This is strictly used for CROSS or body use only or is diluted for use. This is never a beginner peel. This percentage is NOT recommended for ethnic skin tones.

How deep can a TCA peel penetrate into your skin?

TCA acid peels can penetrate quite deep into the skin and are regarded as a medium depth peel. When applied in multiple layers; TCA peels can penetrate down into the epidermis and even a bit into the upper papillary dermis. This is beneficial for many skin concerns such as hyperpigmentation, fine lines and scarring since they tend to run as deep. Regular hydroxy acids peels cannot penetrate past the Stratum Corneum, so they are considered more of a superficial peel, very superficial peel, or just an exfoliation.

TCA Peel Recovery Time

Recovery time will take approximately one week. In applying this peel, we are purposely creating a controlled burn to stimulate tissue regeneration. There is a typical process which occurs during healing following application of a TCA peel.

On the first day of your peel your skin will be smooth, tight, and possibly a little bit pink. I recommend keeping your skin well hydrated with emu oil/hyaluronic or another moisturizing product such as Hydrophor. Within the next 2-3 days, your skin will be tighter and could feel dry, and may appear darker on surface areas. Wrinkles and fine lines may look more prominent as the skin is preparing to come off. Depending on the percentage of acid you applied, and the number of layers, you will begin to see flaking on days 3-4. Flakes will begin on the areas of your face that are in motion such as around the mouth and nose. It will take another 3 days or so for the flaking to stop. It is important to refrain from picking off peeling skin.

The debate versus dry or moist skin during healing.

There are conflicting opinions between most Dermatologists as to whether or not you should allow your skin to dry up (I.e., the thought is that it is better for peeling) or you should hydrate it. Most dermatologists and I recommend that your skin always be hydrated. In allowing the skin to become dry, you run the risk of excessive itching or a possible cracking and tearing of the skin with facial movement. Dry skin results in extra tiny flaking. A hydrated face will not only feel more comfortable, but the flaking will peel off in larger, more manageable pieces. Hydrating does not impair or change the effects of a peel.

What kind of peeling can you expect with a TCA peel?

The variation in peeling is huge, as TCA is such a customize-able peel. I recommend clients begin with the 13% peel and not move up until you are unsatisfied with a 5-layer peel. That is the ONLY reason to ever move up in strength. *Never get a 20% just because you want to "peel more". It is the layering of the peel that cause the flaking.

TCA 7% - 1 layer: provides exceptionally light flaking. No frosting at all is observed during the application process. Results in very mild feeling. Tingling or itching may be present during the peel.

TCA 13% - 1 layer: results in very mild fllaking. Barely noticeable flakes that are super easy to manage. No frosting is likely to occur during the application process. This results in very mild peeling. Mild tingling or itching occurs.

TCA 13% - 2-3 layers: results in moderate flaking for a period of 3-4 days. There is no browning. Skin appears slightly crinkly in appearance for a few days. There may be a few spots of frosting occur here and there. Cheeks, forehead, and nose area are possibilities. Tingles at each layer, could feel a bit of stinging depending on sensitivity for a few minutes.

TCA 13 - 4-5 layers: results in a deeper peel. You should see frosting during this application process and will feel stinging on layers 3-5 that will gradually go away by the end of the 5 minutes between applying layers. Slight browning should occur in the outermost layers of dead skin. It turns brown because the skin is no longer attached. It is truly "dead" and will peel off. *If you have undergone an Obaji peel (which consists of 3-5 layers of a 15% or 20% solution) or have been treated with 13% TCA Peel at 5 layers consistently, then you may be ready to move up to single layer of the 20% TCA Solution. Again, caution should be used depending on your Fitzpatrick number. One should always receive a prep with a melanin inhibitor or Hydroquinone product prior to undergoing a high % TCA peel for a minimum of 2 to 2.5 weeks prior to undergoing a peel. This helps avoid or greatly diminish the development of post-inflammatory hyperpigmentation.

It is important to remember that you do not always have to actually peel following a TCA peel to see the benefits. Visible peeling is just a side effect, The actual ‘peeling’ occurs at the cellular level. Many people will find that their flaking is quite minimal after a series of peels.

TCA Peel Side Effects

Any chemical peel may result in undesired outcomes. That is why preparing the skin prior to a peel is of paramount importance. To ensure we minimize any complications, it is important to follow the recommended protocol.

PIH - Post inflammatory hyperpigmentation occurs when the skin becomes inflamed/damaged/wounded. The epidermis stimulates melanin production, and a brown patch will appear after healing. A common example is when a dark spot appears after the inflammation of a pimple is healed. This PIH may take several weeks to months to fade. By applying a broad-spectrum SPF of 30+ daily, a daily antioxidant, Retinol Vitamin A, and a fade gel daily, this outcome can be greatly minimized or avoided entirely.

Scarring - Scarring after a chemical peel is uncommon. If you are among those that have a history of keloidal scarring, it would be best to avoid peels in general. In these cases, I recommend using a topical acid serum or Retinol instead.

Redness - A continued state of redness is not common with a lower strength TCA acid peel. This more commonly occurs with a Phenol peel.

Infection - The TCA itself will not cause an infection, but if you are Herpes simplex positive, the peel irritation itself could result in an activation of a cold sore infection. If you are Herpes simplex prone, I recommend Acyclovir prophylaxis prior to undergoing any chemical peel application.

Because burning, irritation and itching, stinging sensations are uncomfortable, the TCA peels performed at Regenesis Medical Spa contains a “Cooling-Action” additive that will make this the most comfortable TCA peel you have ever received. This additive assists in minimizing the 'burning effect' that many clients experience with application of stronger acids. This cooling action allows for a more comfortable peel for clients.

To see if you might benefit from a TCA peel, please call 504.400.6480 to schedule a complimentary consultation.

5 Dermatologist approved ways to get rid of hyperpigmentation

#Having discoloration (hyperpigmentation) and uneven skin tone on your face can lower your self-esteem and self-confidence and, worse, can build stress and anxiety. One study about women with hyperpigmentation issues reported that it could negatively impact their mental health.

Are you one of those who experience the same hyperpigmentation problem? Fortunately, many approved hyperpigmentation treatments can effectively treat discoloration and patches in your skin!

What is hyperpigmentation?

Hyperpigmentation is the dark patches in your skin. This discoloration happens because there is abnormal melanin production (the brown pigment that produces standard skin color).

There are various types of hyperpigmentation, including melasma, sunspots, and post-inflammatory hyperpigmentation.

Melasma. Melasma is commonly known as the mask of pregnancy. It is frequently acquired during pregnancy due to the increase in the reproduction of hormones in the body.

Sunspots. Sunspots are sometimes referred to as liver spots. It occurs because of too much exposure to the sun.

Post-inflammatory hyperpigmentation. This type of hyperpigmentation is a result of inflammation of the skin. One example of this is the spots caused by your pimple or acne, which results in dark marks or scars on your face.

Hyperpigmentation is a common skin condition that may occur to anyone. However, there are counter-treatment that improves the skin and reduces the appearance of hyperpigmentation.

1. Microneedling treatment.

Microneedling is a minimally non-invasive procedure intended to help lighten the dark spots by encouraging your skin’s wound-healing response. It uses fine needles to create micro” injuries” to trigger the body’s natural response of healing, forming a new, healthy skin can that matches your normal skin tone, which reduces the appearance of dark spots.

Studies support the positive result of microneedling for treating hyperpigmentation, specifically melasma conditions. One article published that microneedling treatment in 22 patients of melasma showed significant results (successfully lightened their dark spot), making skin needling treatment effective for hyperpigmentation.

2. Chemical peels.

A chemical peel uses high concentration acids to treat the preferred area of skin. Types of chemical peels may use azelaic acid, kojic acid, glycolic acid, or salicylic acid, along with sun protection. These treatments can lessen the presence of hyperpigmentation by removing the outer layer of the skin. Deeper varieties may also infiltrate the intermediate layer of your skin to create more melodramatic results.

There are various types of chemical peels based on the skin’s needs.

Superficial peel

It uses glycolic acid, salicylic acid, which eliminates thin skin covers, decreasing pigment and seeming dryness. Although the first session’s result may be unsatisfactory, remarkable improvement will be noticeable after repeated peelings.

Medium depth peel

The most usual chemical used for a medium depth peel is Trichloroacetic acid (TCA). The concentration of TCA usually ranges from 20–35%. It can lead to a notable improvement in skin texture, decreasing pigmentation, freckling, and dry sunspots.

Deep peel

A deep peel uses phenol. However, deep facial peels may cause scarring. Nevertheless, it is very effective at improving both surface wrinkles and deep furrows, including hyperpigmentation issues.

3. Hydroquinone

In treating hyperpigmentation skin-related issues, hydroquinone has been the gold standard for over 50 years. It works by bleaching the skin, which can be helpful when treating different forms of discoloration problems.

Hydroquinone has been regarded as safe and effective by the FDA since 1982. The OTC-approved (over-the-counter) standard concentration is 2%. In rare cases, hydroquinone may cause a condition called ochronosis. A consultation is recommended for sensitive skin before trying the treatment.

Irritation caused by sunlight is possible after the treatment. So, it would be best if you avoid prolonged sun exposure, tanning booths, and sunlamps. In addition, sunscreen and wearing protective clothing on the treated areas of skin is a must-have.

4. Microdermabrasion

Microdermabrasion is essentially safe for everyone. In microdermabrasion treatment, using anesthesia is not needed. It works by eradicating cells from your outermost layer of skin, which encourages new cells to redevelop rapidly than they would normally. This results in more firmly toned and more youthful skin.

Some people try microdermabrasion for treating hyperpigmentation. For example, in a 2012 study, women who were given a combination of microdermabrasion and laser therapy experienced substantial progress in their skin tone.

There are two types of microdermabrasion:

Crystal microdermabrasion. This technique involves using the wand to remove tiny particles on your face.

Diamond-tip microdermabrasion. It uses an applicator that makes direct contact with your skin as it exfoliates.

Both methods work by relaxing and eliminating dead skin cells to reveal younger-looking cells.

5. Laser Resurfacing Treatment

Laser peel (resurfacing) treatment uses high-graded beams of light to reduce hyperpigmentation.

There are two kinds of lasers: ablative and non-ablative. Ablative lasers are the most powerful, and they involve eliminating layers of your skin. Non-ablative procedures, on the other hand, aim at the dermis to stimulate collagen growth and tightening effects.

However, Ablative lasers may work better for people with fair skin. For some, non-ablative versions may cause the skin to blacken instead of lightening. That’s why consultation is very important before the treatment. Work with your provider to evaluate your discoloration and overall skin tone to hand-pick the best option for your skin.

Discuss possible treatments for your hyperpigmentation! For hyperpigmentation, Indulge Aesthetics recommends that along with the treatment, proper skincare and protection from sunlight will remarkably improve the skin. Discuss with a trained professional the best treatment for your skin type and let the experts provide you with safe and effective treatment.

CHEMICAL PEELINGS

Consisting of the application of a chemical substance to the skin, with the purpose of the removal of layers of skin, varying depending on the depth of the chosen peeling. The most superficial (glycolic, HPP, melaspeel, salipeel…) are indicated in cases of slight solar damage (post-summer) or to improve acne, while medium (TCA) and deep (phenol) can be applied to wrinkles and acne scars. Chemical peeling treatments look to produce the renewal of the coetaneous surface to a certain depth through the application of substances that produce a chemical affectation of the skin up to a different level. The grade of depth necessary for the peeling to take effect is determined by the deepness of the lesion and the objective to treat.

PEELINGS TYPES

In this way, Peelings are classified as:

Superficial: Glycolic and other Alpha Hydroxides.

Medium: Trichloroacetic up to 25-35%.

Deep: Phenol, Trichloroacetics of 50%.

It must be your dermatologist who decides with you which type of Peeling is suitable. We have to keep in mind that the deeper the Peeling the better the results. With appropriate Peelings we can remove skin stains, many benign pigmented skin lesions like hyperkeratosis of the neckline, hands, and wrinkles. Wrinkles can be completely removed when they are not found in the Dermis Media. We must not affect the skin deeper than the Dermis Media if we want to obtain a complete regeneration of new, clean, elastic skin with no wrinkles. You should also know that the deeper the level of the Peeling, the number of days of recuperation and regeneration for the skin is longer: a glycolic peeling allows for the use of makeup immediately following and is practically imperceptible, however medium and deep peelings require a few days of avoiding normal activity. When Medium and Deep Peelings are done it is necessary to maintain rigorous protection from the sun for no less than three months.

One of our dermatologist will provide you with personalised information of the treatment that best suits your needs.

Microdermabrasion or Chemical peels, or Both?

Your age signs are almost appearing on your face? Feeling less satisfied and less confident with the appearance of crow’s feet, marionette lines, wrinkles…etc.? Do you already suffer from scars such as acne scars?

Does your skin deal with sun damage spots or pigmentation inconsistencies? Did you recently notice while looking up to the mirror the appearance of saggy skin and now you are looking for tightening procedures to perform?

If your answer for all or most of the previously mentioned cases is yes…

You don’t have to worry at all!

Because the world is full of many cosmetic procedures that can deal with all of the mentioned cases such as Chemical Peels or Microdermabrasion. Both of them can work effectively on your imperfections however, you must take into consideration and seek a professional dermatologist in order to provide you full information about the procedures that suit your skin type, color, and condition the most.

After seeking a dermatologist you may also need to confirm the information especially if you hear two different options for the same case. So, you must search for more information and we can start our role by providing you most of the information needed about Chemical peels and Microdermabrasion in treating acne scars, wrinkles, face lines, sun damage, and pigmentation inconsistences…you are just had to keep scrolling.

Generally, Chemical peels and Microdermabrasion procedures are almost similar as they mainly work for skin exfoliation, removing all of the dead skin found and stimulate the production of new cells, therefore, giving you the most luminous, healthy, fresh, and youthful look.

How Microdermabrasion and chemical peel works?

Microdermabrasion works through using a fine jet that is able to provide a fine stream of crystals or a diamond chip which is mainly directed to the affected area replacing the dead skin with new healthy ones, stimulate blood flow, and encouraging the cell to produce new collagen and elastin.

Chemical peels, work through to enhancing the overall skin status of either the face or body; they are working for the destruction of specific skin layer; as a result, the dead skin’s layer peeled off and a new, fresh, smooth, and healthy skin is regenerated.

Both of them have many types, therefore, each type can work differently from one another, however, all of them work for the same purpose, which is exfoliation.

Recommended: Best At-Home Exfoliator For Face – High-Quality Face Scrub Cream

What are the types of microdermabrasion and chemical peels?

There are types for both of them…let us discuss them briefly. Let us start with microdermabrasion because it has only two types as follows;

Crystals Microdermabrasion Device

This machine mainly works by using natural crystals such as aluminum oxide (corundum) crystals due to its hardness property are commonly used. Sometimes, magnesium oxide, sodium bicarbonate (baking soda), and even sodium chloride (salt) crystals are used as well. The crystals perfectly provide an effect on the treated area giving the luminous face that is free of any imperfections.

The previously mentioned crystals are considered as safe, non-carcinogenic, and does not cause any kind of allergy.

Diamond-tip Microdermabrasion Device

This machine is almost similar to the crystal microdermabrasion machine however, this machine uses a wand with a diamond tip that mainly passed over the affected skin causing the removal of the dead skin that is then vacuumed away giving you a luminous and perfect skin that is of any kind of imperfections.

Can I perform both procedures together?

Yes, some dermatologists recommend using both procedures together however, this depends on your skin condition, your choice for a good dermatologist, your capability to spend extra money. Many research has done on this point; one of them is a study entitled “The Effectiveness of a 5% Retinoic Acid Peel Combined with Microdermabrasion for Facial Photoaging” it has been found the following.

“By using microdermabrasion on the skin, topical therapeutics can be applied at the conclusion of the treatment, which will reach levels much deeper than when typically applied to the surface of the skin, as the skin barrier function of the stratum corneum is temporarily compromised [18]. Therefore, slightly greater improvements in the histological features of photoaging can be achieved with the combination of microdermabrasion followed by a 5% retinoic acid chemical peel versus a 5% retinoic acid chemical peel administered alone”

“The combination regimen used in this study was shown to be safe and effective for the treatment of moderate to severe photoaging at a follow-up of 24 weeks after treatment initiation. Additional clinical studies with larger populations and more objective methods for clinical evaluation would further reveal the efficacy of this combination treatment for moderate to severe photoaging.”
