With the hatchery test just finished and us being neck deep in cleansers, let's kick off a cleanser refresher. So why a cleanser? Aside from the simple functional step of washing off the day's grime (sunscreen, makeup, gym sweat etc.), it actually plays an important part in our long term skin upkeep. The accumulation of air pollutants throughout the day can sling to the skin's surface and promote skin congestion and inflammation. What's worse is that these pollutants can compound damages induced by UVA and lead to premature aging. *Hiss *booooo Now there are all types of cleansers out there so here's an instabrief breakdown of some cleanser types: Bar: Typically a gentle pH friendly option (con: annoying to store) Powder: Usually pH friendly and brings gentle exfoliation benefits. (although it can be messy) Balm: Travel friendly version of an oil cleanser (greasy AF) Oil: gentle yet thorough cleanse that can double as a makeup remover (annoying to travel with) Cream: oftentimes soap based for that luxurious foamy experience (con: high pH which can be irritation and stripping) Gel: can find good skin friendly pH options (con: the cleansing experience can be really meh) Micellar: gentle, lighter version of a true biphase makeup remover (con: runny application, requires cotton pads) No matter what type of cleanser out there, just help your skin out and don't forget to give your face a wash. Personally we're not particularly picky with our cleansers. ⭐️What's your cleanser of choice? #cleansersinabunch #notsobasicfacewash #washthegrimeoff #citypollutionwoes

Let's start the week of with a simple #decodethatIL. Today we're looking at Glossier's Super Glow, that solely features Vitamin C derivative, aminopropyl ascorbyl phosphate (AAP). Because of classical L-ascorbic acid being so unstable, you'll often find a lot of other intriguing derivatives out there. For AAP, we were only able to find third party invitro study and one tiny clinical from the supplier of n=33 showing that 0.5% AAP has the potential to reduce pigmentation and wrinkles and that's about it. Unfortunately because of that, we can only give it (**.5). For those of you that struggle with regular L-ascorbic acid, and you're trying to incorporate vitamin C somehow someway, we'd probably recommend going for magnesium ascorbyl phosphate instead. Just know that in general, while these derivatives may sound appealing, the data behind these are few and far between and a lot of the data gravitates towards pigmentation. In a nutshell: If your skin can tolerate ascorbic acid, no reason to switch to this at all. If you're a vit C derivative fan, we're not entirely sure if we'd try this either. Chemist struggles: supplier data can be a helpful preview, but often times they only share a small, flattering snippet #vitaminC #LAAanditscousins #mondaybasics

Hoozah! It's #nye so let's take a look back at some of the chemists' favorite posts and moments of the year. 1. Fan favorite this year is our actives relationship map! We are definitely expanding this in 2019 2. That time Gloria tried to make a helpful visual of vitamin c powder use then realized that her hand is the size of a toddler's 3. Favorite new graphics! Victoria drew stylish cartoon s to breakdown retinoid pathway in skin. Oh and we talked smack about retinyl palmitate 4. We decided that it was time to show face but both of us are too camera shy so we had to grab a drink first 5. Our grumpy 'horny layer' 6. That time we spent an hour foraging in the neighborhood to make a banner image for our website Phew! What a year. Thank you all for being amazing. What was your favorite Chemist Confessions post of the year? Happy New Year!!

Research on the correlation between milk consumption and acne has largely been controversial. Some studies find an effect and others find none.⁣⁣⁣ ⁣⁣⁣ A meta-analysis is a way for researchers to pool the results from multiple studies. This combining increases statistical power. Higher statistical power reduces the chances of a Type II error, which is concluding there is no effect - when in fact there is one.⁣⁣⁣ ⁣⁣⁣ Human studies looking at the effect of diet are often not experimental. Data is usually collected by a retrospective survey, where people are asked how often and how much they've consumed over the past year, decade, etc.⁣⁣⁣ ⁣⁣⁣ A group of researchers led by R. Dai at Ningbo University performed a meta-analysis of studies looking at milk consumption and acne. They looked at variables including; frequency of consumption, type of milk (full fat, low fat, and skim), geographical location, and severity of acne. The studies were also examined for bias.⁣⁣⁣ ⁣⁣⁣ Of a total 212 studies found, 13 met the criteria for inclusion.⁣⁣⁣ ⁣⁣⁣ Using data from these 13 studies, the researchers estimated that there was about a 1.16 odds ratio (95% CI 1.10-1.24) for someone who consumed milk to have moderate-to-severe acne compared to someone who didn't.⁣ ⁣ That means if you were to randomly select one person each from groups of milk drinkers and non-milk drinkers, you're about 16% more likely to encounter someone with moderate-to-severe acne in the milk drinking group.⁣⁣⁣ ⁣⁣ If you found 10 people with moderate-to-severe acne in a group of 100 non-milk drinkers, you might expect to find 11 or 12 people with moderate-to-severe acne in a group of 100 milk drinkers.⁣⁣ ⁣⁣⁣ Looking into the data further, the researchers found the association was strongest with European and North American milk drinkers, moderate-to-severe acne, and skim-milk had a stronger influence than low-fat and full-fat milk. They also found no association between milk drinking and mild acne or subjects in Asia, Africa, and South America.⁣⁣⁣ ⁣⁣⁣ The researchers point out that more research needs to be done in Asia, Africa, and South America.⁣⁣⁣ ⁣⁣⁣ DOI: 10.1111/jdv.15204

I saw this myth twice today. I couldn't even begin to work out how to formulate a pithy "truth" to this, so I ended up writing a full blog post! There's some bits which are sorta kinda right, but it's mostly just very wrong. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ Thinnest to thickest is a good general rule of thumb, but this isn't why. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ Swipe for a quick graphical refutation, check out the link in my bio & stories for a longer deconstruction ⠀⠀⠀⠀⠀⠀⠀⠀⠀ #skincaremyth #skincarescience #molecularsize #chemistry #beautyscience #beautymyth #skincareroutine #skincarelayering #skincaredaily #instaskincare #instabeauty #beautyroutine #skincareaddiction #skincareaddict

‍♀️"Micellar" is a marketing term to call this category of cleansers. There are generally two types of micellar waters: diluted-surfactant/solvent water and bi-phase makeup removers. If you have the bi-phase micellar waters, it'll come with a silicone/oil solvent phase to help with the heavy duty long wear makeup. So do treat it just like a regular makeup remover and use a second wash. We're going to leave these out of our study since it's not very interesting as they should all do very well in makeup removability. Instead, we're focusing on the second type, the diluted surfactant/solvent water type. This category doesn't necessarily mean hoaky, it's just that the cleansing power is going to be pretty product dependant and will come down to figuring out just how "diluted" these really are. What it also means is that the formula will be pretty gosh darn gentle and the cotton pad definitely aids in swiping it clean. Also, fun fact, another testament to micellar being a marketing category are all the other "micellar" products. Spotted are these micellar cleansers, no cotton pad required. Ok let's be real, these are just gel cleansers with a familiar ingredient: coco betaine. *Edit- forgot to include IL. If you want to see it, check out our story. In terms of testing conditions we're planning to use the same makeup adversaries. We'll control the amount that goes on the cotton pad and get-a-swiping. Probably limit to three swipes...? if it doesn't prove very successful we'll run it again with the soak and sit method. Time to put makeup on Zain again! ps. to add to the pronounciation debate, we pronounce it "miss-suh-lur" @sjk90109 #themicellarname #micellaniousfacts #cottonpadwork #micellartypes
