Are parabens really harmful?

Parabens are a class of chemicals that are commonly used as preservatives in cosmetics, personal care products, and some food products. There has been some concern in recent years that parabens may be harmful to human health, particularly in terms of their potential to act as endocrine disruptors, which are chemicals that can interfere with the body's hormonal system.

However, the scientific consensus on the safety of parabens is that they are generally safe for use in cosmetics and personal care products at the concentrations typically used. Regulatory agencies such as the US Food and Drug Administration (FDA) and the European Union's Scientific Committee on Consumer Safety (SCCS) have evaluated the available evidence and determined that parabens, when used as directed, do not pose a significant health risk to consumers.

That being said, some individuals may be sensitive or allergic to parabens, and may experience skin irritation or other adverse effects as a result. In addition, some people may choose to avoid parabens for personal or environmental reasons, as they are not biodegradable and can potentially accumulate in the environment over time.

Overall, while parabens have been the subject of some controversy, the weight of scientific evidence suggests that they are generally safe for use in cosmetics and personal care products, and are an effective means of preventing microbial growth and extending the shelf life of these products.

We experience most emotions physically rather than in the brain and anyway that’s just to say I hate just being forced to feel whatever the last person was feeling for no fucking reason

The newest video from lab muffin beauty science seems like exactly up the alley of someone with your crusade for fact-checking. It was a wild ride of enlightenment, highly recommend.

Oh this is REALLY interesting. Thanks for the recommendation!

I first noticed the benzoyl peroxide scare when someone mentioned it in a post I made about the Radium Girls story inducing "what are they hiding from us now?!" anxiety, and I looked it up. I don't use any products with that ingredient at the moment, but it seemed worth checking into. And despite me not being a scientist, the fact that the benzene levels they cited showed up at VERY high temperatures seemed...off. Like how frequently are the products ever at those temperatures? "Maybe in a hot car?" I thought, but still wondered how often acne cream is left in a car in Australian high summer for that long.

And hey- the history professional with little chemistry knowledge was right! Seems like even ordinary laypeople can see the issue here if they just read the study even a little bit.

But because humans respond more to dramatic headlines- and, not going to lie, because we've been primed to believe in this by companies CONSTANTLY doing it for real throughout history with heavy metal dyes, radium, tobacco products, asbestos, fossil fuels, PFAs, etc. -you get "we're all rubbing cancer on our faces!!!!" reactions.

Really highlights the need for a balance between watching companies like hawks because they've proven that they will kill us if it pads their bottom line, and not falling for junk science.

I love skincare, but I am very, very annoyed by the fear mongering of 'clean' or 'green' beauty brands, and I thought this was a good article breaking down the problems with 'nontoxic' marketing in the beauty industry, if anyone else is interested.

[blorbocedes]

my youtube feed (or the video essays part) is basically matt bernstein, contrapoints, shanspeare, into the shadows, lab muffin beauty science, caelan conrad, of herbs and altars, kat blaque, patrick kelly, melanie murphy, philosophy tube, rowan ellis, kaz rowe, münecat, alexander avila, uncarley, ordinary things etc. not sure if any of those people would be your type of content but they're generally good. can't name any specific videos off the top of my head to recommend but maybe have a look.

im currently watching the uglies movie review by ModernGurlz!

[vhstown]

CAN I GO BACK ON THIS FOR A SEC JUST TO ADD if you're reading any scientific works (books articles studies etc) please read the critiques on it as well ESPECIALLY if it is old !!!!!

AND if you're reading any studies DO NOT TRUST THE ABSTRACT look at the method and results regardless of if it's published in a reputable journal or has lots of citations. if the method is weird and results arent so amazing as the study claims or concludes or they're even calculated wrong do NOT trust the study!!!!!!

guys i read ONE chapter of a genetics book im going to abandon tumblr and cure cancer fr

Dear Zack and Sephiroth,

To Zack: is snuggles allowed?

I'm confused.

Both: Do you know about Northern lights? Have you seen it before?

To Sephiroth: Do you like science? can you explain why?

I'm sorry if that was rude.

To Zack: Which board games you like?

Both: Which plushies are your favorite?

To Sephiroth: I'm sorry, I like your hugs so much! Can you hug me please?🥺💛🩷🩵✨🌟🫂❇️🎇🎆❤️🤗.

Both: You guys are the best!💟.

Zack: Heya Bob! Good to see ya again!! ✨

Zack: Snuggles?? Is that the name of a plushie? Are you asking if he’s allowed in ShinRa Tower…? Heh! I’m just pulling your sock V^ω^V l don’t see why snuggling wouldn’t be allowed in the appropriate locations with the appropriate people! I snuggle up against Seph on the couch all the time! You wouldn’t believe how many times I’ve fallen asleep wrapped in my best bud’s arms, some cheesy movie playing in the back <3 Guy is such a soft serve ice cream come when you get to know him!!

~

Zack: The Northern Lights??? Ooohhhh yeah!! You mean when the sky goes all disco with color!! I personally haven’t seen them during my own lifetime, but they sure do make beautiful desktop screensavers!

Sephiroth: Ah, yes. You’re referring to Aurora Borealis. Despite never seeing it myself, I am indeed aware of the natural phenomenon.. It is actually caused by the planet’s electromagnetic field interacting with particles from the sun, which was only one of the many facts I researched while a small child in the labs. Astronomy and geoscience have always been favorites of mine, to answer your other question.There is also no need to apologize; your query is perfectly appropriate. But to reiterate—yes, I am indeed an avid readers science nonfiction, predominantly homing in on the study of space and natural phenomena that occur on the planet. I suppose this stems from being surrounded by such a rich scientific atmosphere as a child. However, while my “father” studies biochemistry, I have strictly chosen to focus my studies on other fields. I am not interested in cellular matters, and I don’t think I ever will be.

~

Zack: Ooh! Good question!! I think I gotta spring for Jenga!! (Whiiiich I think counts!) ✨ There is really nothing funnier on this planet than watching Seph decide which block to move like each piece is a wire attached to a bomb or something. It’s good stuff!! OOH! Also Twister!!! (P.S!! DO NOT PLAY THIS GAME WITH SOMEONE WITH KNEE-LENGTH HAIR YOU WILL GET TANGLED LIKE A MEATBALL IN SPAGHETTI.)

~

Zack: My favorite plushie?? Easy cheesy! That’s my ol’ pal, Muffin… AND his twin brother, Stuffin, who’s another little dragon dude who Seph stitched up for me on my birthday. Never can I miss a night without them!!

Sephiroth: Hmph. I do not own many “plushies”… barring the one Zack purchased for me, of course, to commemorate the one-year anniversary of our friendship. So I suppose my answer would have to be my stuffed Ifrit.

~

Sephiroth: Heh. I never knew someone besides Zack could be so fond of my embraces. It is actually… quite nice. Most people are afraid of me, you know. It’s most certainly a chance of pace. Ergo, I accept your request for another one.

*still stiff, but noticeably less awkward, Sephiroth puts both his hands on your shoulders in a vague embrace. the contact lasts for about four seconds.*

Sephiroth: I hope that was adequate ^_^

~

Zack: NO U, MY FRIEND!! YOU’RE THE BEST!!! 🎉🎉🎉🎉🎉

Sephiroth: Heh… so I’ve been told. But the words are always less hollow when coming from a genuine soul.

Hi! I'm Michelle, chemistry PhD, science educator and cosmetic chemist, and I'm here to help you figure out which beauty products are and aren't worth buying, using science

Website--with links to YouTube and TikTok versions of the posts' information--discussing a lot of misinformation about how 'dangerous' the 'chemicals' in beauty products (including things like sun screen) actually are

[creakingsweetbaytree]

I just want to be environmentally concious but all the affordable sunscreen has coral reef killer in it :(

Edit: I learned it is a much more complicated issue than I thought! Generally you can use any sunscreen because so little makes it into the ocean, I recommend Lab Muffin Beauty Science's video on it

[saintlaurentproblems]

There’s a cosmetic chemist on TikTok who’s known for posting about skin care products and debunking myths about popular skins products and she posted about Rhode’s lip balm and said it’s basically grainy because of the Shea butter in it and it’s a common thing that happens with products that have a lot of shea butter and suggested putting it in warm water and the massaging the tube to get the crystals to dissolve

Her TikTok is called lab muffin beauty science

since people in the tags are complaining about bad sunscreens, I'm going to offer some gentle advice on finding decent sunscreens because you do actually genuinely need one if you're going to be outside longer than a few minutes.

the sun is actively spitting particles of radiation that will try and tear your atoms apart.

"chemical" sunscreens are generally more comfortable than "mineral" sunscreens. they also aren't as likely to cause a white cast. there is a lot of misinfo about them on the market, but they are considered generally safe (aside from allergies).

you need to apply 1/4 tsp of facial sunscreen for full protection, and one ounce on your body for full protection. yes, that's a lot.

in general, any sunscreen is better than none! but you DO have options and there are cosmetically elegant formulas on the market. Asian and Australian brands tend to have very good formulas, as well as having access to better UV filters than American brands.

EU brands are usually given a lot less restriction than Australian and American brands, as the US and Australia both regulate sunscreen as a drug and a lot of the EU does not. IIRC, Japan and Korea also regulate sunscreen as a drug.

Finally, if you want to hear an actual cosmetic chemist explain sunscreen and common misconceptions and misinfo about it, please check out Lab Muffin Beauty Science

be pro-aging but wear sun screen. sun protection is not beauty industry propaganda it will save you. wear it. or else.

What do you think about using cyperus rotundus oil for removing/decreasing unwanted hair growth? I keep seeing it pop-up everywhere recently, but I can't seem to find any solid scientific sources.

Everything I have to say on the topic from a scientific perspective has already been said right here, and much better than I ever could!

From an anecdotal perspective: Cyperus rotundus (called oyarsalam or abiyarsalam where I come from) is a terrible weed that really afflicted the paddyfields in my hometown. It’s very well-known in my region, and although I’ve never heard of it being a hair removal/reduction agent from my folks back home, it’s possible that there was some folk remedy at some time or another that used it. I’ll call up my grandmother and ask her if she knows—send me another ask in a few days, and I’ll report back!

Shout out to Michelle Wong (Lab Muffin Beauty Science) for calming my anxious paranoid ass down about the benzene panic in sunscreen and benzoyl peroxide
