lets talk skincare⋆.ೃ࿔*:･🎀

disclaimer i am NOT a dermatologist so to create this post i did LOTS of research and i'll link all of my sources at the end of the post. i just wanted to kind of put everything that i found in here so i hope its helpful 💕🗒️

HOW TO DETERMINE UR SKIN TYPE ;

wash ur face with a gentle cleanser, pat dry and wait for about 30 minutes. if ur skin appears shiny throughout then u have oily skin, if ur skin appears tight/flaky then u have dry skin.

if u notice a slight shine on your nose and forehead then you have normal skin. if you have a combination skin type, then the skin will get oily around the t-zone.

INGREDIENTS TO LOOK FOR ;

for skin with acne -> salicylic acid, benzoyl peroxide, sulfur and mandelic acid.

for dry skin -> lactic acid, hyaluronic acid, ceramides and glycerin.

for pigmented skin -> mandelic acid, niacinamide, vitamin C, and arbutin.

INGREDIENTS THAT U SHOULD NOT MIX ;

mixing retinol and vitamin C causes irritation, mixing vitamin C and glycolic acid results in over-exfoliation, mixing AHA and retinol causes extreme dryness.

INGREDIENTS THAT U SHOULD MIX ;

hyaluronic acid + ceramides = repairing skin barrier. niacinimide + salicylic acid = healing acne. retinol + niacinimide = collagen production.

GLOWY SKIN TIPS ;

use a cleansing balm to cleanse ur face to remove all the impurities from ur skin

use serums to hydrate ur skin

lather on moisturizer, dont put too much to the point where ur skin cannot produce its own oils, but you MUST moisturize

apply sunscreen everyday, not only on ur face but also on ur neck and hands

face masks 1-2x a week

get enough sleep, drink enough water, and steer clear of overly processed foods

SKINCARE DOESNT STOP AT UR CHIN ;

its important to take care of the skin on ur neck for SO many reasons because skincare doesnt stop at ur chin. ur neck reflects the first signs of aging, and its most susceptible to sun damage so show it some love!

use the same products that u use on ur face on ur neck also, moisturize ur neck and always apply sunscreen, lastly, use some retinol to build collagen.

HOW TO APPLY RETINOL ;

when applying retinol, use a pea sized amount. avoid application around ur eyes and the openings in ur nose, and use retinol in ur night skincare routine only.

HOW OFTEN TO USE SKINCARE ;

retinol should be used nightly (1-2x a week for beginners). hyaluronic acid should be used (2x a day). salicylic acid should be used (1-2x a week). sunscreen should be applied daily, no need to apply it at night and if u can, you should reapply it every 2-3 hours. vitamin C (1x a day in the morning).

SERUMS FOR UR SKIN-TYPE ;

for oily skin use -> salicylic acid, niacinimide and mandelic acid.

for dry skin use -> hyaluronic acid, ceramides and lactic acid.

for normal skin use -> vitamin C, glycolic acid, and retinol.

for aging skin use -> peptides, retinol and vitamin C.

for acne prone skin use -> salicylic acid, retinol, and niacinimde.

for combination skin use -> mandelic acid, niacinimide, and glycolic acid.

WHAT TYPE OF FACEMASK IS BEST FOR YOU ;

cream masks are good for all skin-types and it soothes and moisturizes. clay masks are good for oily or acne prone skin and it absorbs oil and controls shine. charcoal masks are good for oily or acne prone skin, and it deep cleanses and unclogs.

sheet masks are good for all skin-types, it nourishes and hydrates. enzyme masks are good for all skin-types and it gently exfoliates and brightens the skin. bubble masks are good for all skin-types and it hydrates and soothes.

gel masks are good for all skin-types and it provides a cooling effect. exfoliating masks are good for all skin-types BUT if u have sensitive skin then exfoliating masks are not for you. exfoliating masks remove dead skin cells and debris.

HOW TO LAYER UR SKINCARE ;

in the morning (cleanser + toner + hydrating serum + vitamin c + moisturizer + sunscreen) in the evening (double cleanse + toner + hydrating serum + retinol + moisturizer)

Cloaked similarity between HIV-1 and SARS-CoV suggests an anti-SARS strategy - Published Sept 21, 2003

Yes, you are reading that date right

Never let them tell you "we didn't know the risk." They knew. They just ignored all epidemiological best practices. For corporate profit.

Abstract Background Severe acute respiratory syndrome (SARS) is a febrile respiratory illness. The disease has been etiologically linked to a novel coronavirus that has been named the SARS-associated coronavirus (SARS-CoV), whose genome was recently sequenced. Since it is a member of the Coronaviridae, its spike protein (S2) is believed to play a central role in viral entry by facilitating fusion between the viral and host cell membranes. The protein responsible for viral-induced membrane fusion of HIV-1 (gp41) differs in length, and has no sequence homology with S2. Results Sequence analysis reveals that the two viral proteins share the sequence motifs that construct their active conformation. These include (1) an N-terminal leucine/isoleucine zipper-like sequence, and (2) a C-terminal heptad repeat located upstream of (3) an aromatic residue-rich region juxtaposed to the (4) transmembrane segment. Conclusions This study points to a similar mode of action for the two viral proteins, suggesting that anti-viral strategy that targets the viral-induced membrane fusion step can be adopted from HIV-1 to SARS-CoV. Recently the FDA approved Enfuvirtide, a synthetic peptide corresponding to the C-terminal heptad repeat of HIV-1 gp41, as an anti-AIDS agent. Enfuvirtide and C34, another anti HIV-1 peptide, exert their inhibitory activity by binding to a leucine/isoleucine zipper-like sequence in gp41, thus inhibiting a conformational change of gp41 required for its activation. We suggest that peptides corresponding to the C-terminal heptad repeat of the S2 protein may serve as inhibitors for SARS-CoV entry.

Bath Routine 🫧🛁✨

1. I dim the lights, light candles & play classical music. If candles aren’t available, I use an oil diffuser with lavender or eucalyptus scents.

2. I add Epsom salts, milk powder, a few drops of nourishing oils like rosehip, argan, or jojoba. I also like to add dried rose petals for a soothing touch. If I want to detox, I add charcoal and bentonite clay.

3. I shower before my bath to cleanse my body of dirt, oils, sweat. I will use a shower oil during this step to hydrate, cleanse and exfoliate (will do separate post for everything shower).

Pre bath routine:

4. I dry brush to stimulate circulation.

5. I wash my face and remove makeup if applicable. I then use a face steamer for about 5 minutes to open my pores.

6. I apply my favorite face mask (either DIY or store bought) before stepping into the bath (will do a separate post on this).

In the bath:

7. While in the bath, I lightly use exfoliating gloves or a scrub to exfoliate my body.

8. I massage my face with ice globes to reduce puffiness and stimulate circulation.

9. I sip on tea, a magnesium cocktail, or infused water.

Post bath routine:

10. After my bath, I wash off my face mask and apply toner to close my pores.

11. I apply my favorite serums to hydrate and nourish my skin. After applying serums, I use a jade or rose quartz facial roller to help the products absorb better and promote lymphatic drainage.

12. I apply body oil or lotion all over my body to lock in moisture & keep my skin soft.

13. I apply a nourishing hand and nail treatment to hydrate my hands, cuticles and nails.

14. I brush my hair if I didn’t wash it (separate post on this coming soon).

15. I apply my favorite perfume to feel extra luxurious.

16. I put on a silk robe to complete my relaxing routine.

17. After my skincare routine, I use my LED mask. Your skin is more receptive to hydration after cleansing & applying serums & the mask enhances absorption of active ingredients like hyaluronic acid, peptides, or Vitamin C. It also stimulates collagen production & skin repair.

18. After using the LED mask, I apply a moisturizer to lock in hydration.

Then continue on with my night time routine.

[hellsite-proteins]

I have a bio exam in about six hours (in the afternoon, this is an appropriate hour for me to be awake) and I don't wanna study so I'm gonna recite everything I know about proteins to you.

Proteins can have CHONS, Carbon Hydrogen Oxygen Nitrogen Sulfur. Made up of amino acids. Amino acids have NH2-R-C-H-COOH. NH2 is the amino group and COOH is the uhh carboxyl group? Amino acids exist as zwitterions, with the NH2 becoming NH3- and COOH becoming COO-. Because electronegativity and stuff. There are 20 amino acids (in my syllabus).

Proteins have primary structure (polypeptide chain, the specific sequence of amino acids) listed from N terminus to C terminus. Maintained by peptide bonds. Which is a condensation reaction. The COOH and the NH2 form a bond that looks like CONH. Then secondary structure, which is alpha helixes and beta sheets. Both are maintained by hydrogen bonds. Beta sheets can be parallel or antiparallel, though most of the ones in your blog or antiparallel (but also very short). Alpha helixes are more common and recognisable.

Next is tertiary structure. Four types of bonds in this one: Hydrogen bonds, ionic bonds, disulfide bonds, and hydrophobic interactions. In increasing order of strength, hydrophobic<hydrogen<ionic<disulfide. Disulfide bonds are covalent bonds and very heat stable. Formed by disulfide bridges. Very strong. Sulfur is found on Cysteine so the more cysteine is in a molecule the more heat stable it is likely to be. The single letter code for Cysteine is C. If I say CCCCCCCCCCCC, will disulfide bridges form in my protein? Hm. Ionic bonds is when uhh. Charged particles. Shit I forgot I need to revise this part. Hydrogen bonds are easier, I can identify them by identifying differences in electronegativity- in chem I remember these as FON and H, but in amino acids there's only O and N, no Fluorine. Very common, in most secondary structures. In polar particles or R groups. Ionic bonds are for charged particles, hydrogen bonds are for polar particles. Lastly in hydrophobic interactions, not to be confused with homophobic interactions. Which is when hydrophobic side chains- most commonly stuff with lots of carbon, or sometimes sulfur- gather in the middle of the protein, away from the aqueous exterior.

Next is Quaternary structure, which is when there are MULTIPLE polypeptide chains. Only when multiple polypeptide chains, if not it's tertiary. Not all proteins have these. Bonds are mostly the same as tertiary, I think?

CCCCCCCCCCCCCCCC.

There are globular, fibrous, and membrane proteins. But mostly I have to focus on the globular and fibrous part. My case study for globular proteins is haemoglobin. Haemoglobin has four polypeptide chains in it's quaternary structure, two alpha two beta. It is unclear if the names of the chains have anything to do with whether there are alpha helixes or beta sheets in them. It also has a prosthetic group, a haem group in this case, of iron- I think an Fe2+ molecule? Yeah. Which oxygen binds to. And once oxygen is bound to it it causes a change in confirmation in all four parts allowing it to bind to oxygen more easily. I need to know about sickle cell disease, which is when one of the amino acids- glutamic acid I think- is replaced with a hydrophobic one. Serine? Either way when oxygen is bound to it it's fine but when there's no oxygen there's a hydrophobic patch sticking out, which it doesn't like so the haemoglobin will change confirmation to hide, causing the haemoglobin to clump together in a way that causes the red blood cell to appear "sickle shaped". Also I was wrong it's not serine it's valine.

For fibrous, I have collagen. Which is mostly a repeating sequence of three amino acids- shit I forgot which ones I need to get my notes- glycine-X-Y. Glycine has a very small R group which allows it to fit in the small tight part in the alpha helix. X-Y is usually proline and hydroxyproline. Alpha helix, hydrogen bonds formed. Proline and hydroxyproline have relatively inflexible and bulky R groups which gives the structure rigidity. That's the secondary structure. But collagen is unique in that it has a secondary and quaternary structure, because in tropocollagen it's like three of these alpha helixes wound together. Then each tropocollagen cross links to neighbouring tropocollagen molecules. This is covalent bonds involving lysine residues. Lysine??? Where tf did Lysine come from??? I don't see it anywhere else on the page. This is worrying. Uhh this increases tensile strength and the staggered or overlapping arrangement of tropocollagen minimises points of weakness along the length of the fibrils. It's like, collagenchain-tropocollagen-fibrils-fibres. The staggering gives the bundle of fibrils a banded appearance. There was... A part where they talk about how the cell produces it on the outside... No, wait, that's cellulose. Carbohydrate. Completely different.

Then we move on to enzymes which is a whole different chapter and this is already a very long ask which I imagine will take very long to load. Thank you for letting me ramble in your inbox. CCCCCCCCC. I'm going to ramble about DNA&genomics to hellsitegenetics in a bit but first I need to finish looking through mitosis and meiosis. Ugh. I hope this protein has a high success rate and that my exam has an even higher success rate. Thank you for your time.

this sounds great and i bet you did awesome on your exam! i find explaining things to someone else helpful when studying, so i hope that doing this helped you as well. without even looking at it i can guarantee that your exam was much more successful than whatever proteins i'll get out of this.

i actually had to split this into two proteins and run them completely separately because it was simply too long. i am both excited and absolutely terrified to see what we get from all those cysteines

protein guy analysis:

protein 1 looks absolutely awful. it barely has any secondary structure, and absolutely no tertiary structure to speak of. the horrifying loops have some strings of cis bonds, and there is not a single disulfide bond. i hate this so much. the long string of C's just looks off putting. protein 2 is the same but worse. there is one disulfude, but otherwise barely any structure exists. the single alpha helix feels almost mocking. overall, this is miserable and disgusting.
