So You Want to Restore Your Skin Barrier?
Restoring your “skin barrier” seems like a pretty hot skincare buzzword right now – and it’s actually for good reason! As much as we love our high-efficacy actives like glycolic acid and retinol, our core skincare philosophy is to always first have your skin barrier care down pat before diving into the other more glamorous skin concerns. But what even is skin barrier function and how do you take care of it? The good news is, you’re probably already doing a lot of things that are good for your...
Read moreDo Eye Creams Actually Work on Dark Circles, Puffiness, or Eye Bags?
We’ve been dragging our feet on this topic for a while! The main reason we have been avoiding the big eye cream question for so long is simply because the data here is depressingly sparse. The few studies that exist in the eye cream category can lack logic or have lackluster results. All in all, not the most scintillating or uplifting of skin concerns for us to talk about. However, we can’t ignore the fact that eye area concerns are a big topic. Plus it happens to be a personal concern of our...
Read moreA Chemists' Guide to Navigating "Retinol Alternative" Skincare
Retinol’s popularity has only continued to grow in the past few years with no signs of slowing down. And for good reason! Of the actives out there, it comes with quite a resume of data behind it for reducing wrinkles, hyperpigmentation, and even a little acne assistance. However, with that popularity comes a lot of confusion. Choosing the right retinol product can already be complicated, but on top of that, there’s a whole slew of “retinol alternatives” available on the market. In fact, if yo...
Read moreEverything you need to know about silymarin in skincare
There’s an ingredient that's probbbaaabbbly not quite on your skincare radar yet - but we think it’s worth considering. The ingredient is called Silymarin (sih-lee-mae-rin), and comes from the extract of milk thistle. You'll find it on the ingredient list as "Silybum Marianum Fruit Extract", usually in a handful of clinical brands such as Skinceuticals, PCA Skin, and Dr. Dennis Gross…. And most recently our very own Mr. Reliable 2.0! Silymarin is a potent antioxidant with anti-inflammatory pr...
Read moreActives Pairings With Clinical Testing Behind Them
*Updated as of 5/17/2022 When you start dabbling in actives, you’ll easily fall into the rabbit hole of what you can and can’t layer. One of the complicated aspects of trying to figure out actives layering and why brands may not even be able to give clear answers is simply the fact it hasn’t gone through enough testing to truly know. Not to mention, the formulas these actives sit in can add another layer of complexity. The good thing is there are some active combinations that have been looked...
Read moreAHAs, BHAs...PHAs?! What's a PHA & How to Use
In our final podcast episode of 2021, we dedicated the meat of the episode on a chemical exfoliants update. That’s the alphabet clan of PHAs, AHAs, and BHA, and it resulted in a lot of curiosity about PHAs. Though PHA research is still relatively new and not as well-studied as classic glycolic acid, there’s still some really exciting data that validates it’s use as an exfoliator. In fact, we like gluconolactone so much we use 30% of it in our Baby Steps exfoliating treatment! So let’s do a de...
Read moreThe Chemists Guide to Fighting Wrinkles! PT. 1
So you're ready to tackle some pesky wrinkles eh? Don't worry, the chemists gotchu! The good news is that the skin concern of wrinkles is probably one of the more well-studied aspects in skincare science (even down to the physics and modeling of wrinkle formation!). As a result, more ingredients have been tested in this category than many other areas of skin concern, which is both good and bad. There are a lot of ingredients options to try, but it still requires some sifting through the foo-f...

Read moreThe Chemists' Comprehensive Guide to Cleansers PT. 1
Confession time! We’ve been sitting on this cleanser blog post for probably close to a year. Cleansing is such an important topic -- in fact, we think of it as perhaps the most underrated one of the skincare fundamental trio - cleanse, moisturize, and sun protection. Yet, cleansing is highly personal and very dependent on skin type. So we turned to our Instagram community for inspiration and polled everyone’s top cleansing questions. There are some amazing questions, and it really helped us p...
Read moreThe Non-Vitamin C Antioxidants
The summer season is prime time to experiment with the category of antioxidants. All that extra sun means all that potential for photodamage. But all we’ve been talking about here have been very heavily Vitamin C focused, so what about all the other guys you hear about? The Chemist Have to Do Their Annual Rant But wait! What’s this? Another moment for the chemists to moan about the antioxidant category? The definition of antioxidant has truly been dragged through the mud because everything fr...

Looking for a review on sunscreens?! Well look no further! Summer is just around the corner and the skincare market is already starting to rollout with new sunscreen launches.
