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...

We always talk a lot about the value of clinical tests in skincare and how helpful they can be in making a purchasing decision. Needless to say, we're doing celebratory dances over here because we finally completed our first clinical, designed with all the bells & whistles that we wanted. After 12 weeks of testing our Double Play Retinol Eye & Face Treatment, we’re excited to finally share the results. This has truly evolved into one of our more elaborate projects that took 2+ years to formul...

Reference Every year, as things start to heat up, our thoughts turn once again to sunscreen. What SPF do I need? Mineral or chemical? Is this going to make me stickier than an ice cream on a hot day? How much should I use? (Hey Tiktok, it’s more than 2 fingers’ worth.) To add to the noise, sunscreen often gets caught in the cros...

*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...

Welcome to the Chemist Confessions Blog! We started this blog back in 2018, what was supposed to be our final hurrah to the industry. (Little did we know…) The blog was started with the hope that we could share our insider knowledge of skincare formulation, helping consumers find better products. As skincare users ourselves, we found the skincare world was overwhelmingly saturated and confusing to navigate. Additionally, everyone has their personal skin quirks that don’t fall within the dry/o...

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...

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...
