We’ve put it off for long enough, today we’re jumping into the very new, very hot realm of exosomes. These vesicle structures are getting a lot of attention because they’ve been tied to: stem cells, growth factors, fibroblasts…essentially all the juicy anti-aging good stuff. In this episode, the chemists attempt to make sense of exosomes’ true purpose in skincare, share what benefits they can bring, and explain the current exosome landscape. Strap in because we get pretty nerdy here, but hopefully this episode gives you a good idea of “hot tech” and how it evolves in the skincare world.

Finally, we end on our experiences trying 5 different acne patches on the market. Enjoy!

Continuing our acne series, we’ve been able to delve into some solid actives with pretty juicy data behind it, but there are quite a few less validated ingredients that are pretty popular and worth a look. In this episode, we look at succinic acid, mugwort, witch hazel, and tea tree oil. Four popular plant-ish actives that have gained some traction as magical home remedies for acne breakouts. Let’s see if the data holds up shall we?

When it comes to fighting acne, benzoyl peroxide has been around for so long it almost seems like it’s old-fashioned. However, because of its long history, BPO has a lot of great data and of the ingredients out there we actually have a very good understanding how it works to reduce breakouts. But are we actually using the right concentration? We dive into the research and discuss what concentrations we should all be trying to target and why.

One of the more popular questions we get is about collagen supplements and whether or not it’s a scam. We’d be lying if we said we haven’t been avoiding this one, but no longer! In this episode, we go through the clinical data. We discuss why it’s so hard to shop for good collagen supplements. Finally, we list our shopping tips and things to consider if you’re thinking of adding this to your beauty routine.

After testing 30 sunscreens in 30 days, we’re finally going through our favorites! There was so much to discuss that this ended up turning into a 2 part segment.

Finally, we discuss our favorites for the mineral and tinted category! Hope you enjoy as we tell all in our journey to trialing another 30 sunscreens for 2024.

You probably hear us often championing glycolic acid as the gold standard of exfoliation and a main active to consider having in your routine. However, AHAs are known to cause photosensitivity. Does that means we shouldn’t use glycolic acid during summer months during higher chances of sun exposure? We discuss the data, what skin types should and shouldn’t use glycolic acid, and how to best use this ingredient during summer.

This week we’re taking a break from skincare ingredients, and we’re talking about products. Specifically, toners! Toners will forever be a land of mystery. This category seems to always ends up in the spotlight, there are too many to choose from, and the claims can be all over the place. We decided to break down the product landscape, discuss some of the most popular toners of 2024, and weigh in on which toners we would want to use in our routine. It’s toner time!

When tranexamic acid started gaining popularity a few years back, it felt similar to CBD. Suddenly it seemed like every brand was using it, but there didn’t seem to be a lot of data shared on its effectiveness. In this episode, the chemists share the benefits that tranexamic acid can bring to skin, go through the testing (if any), and discuss whether or not it’s a worthy addition to your skincare routine.

Because of the limitations of azelaic acid, it only makes sense that azelaic acid derviative, potassium azeloyl diglycinate is on the rise! We dive into whether or not this is a good replacement for azelaic acid, what are its actual benefits, and how to use PAD in your skincare routine!
-
The chemists don’t talk about this ingredient as much as they probably should but azelaic acid has a solid amount of data behind it…at the prescription level 15-20% concentration. Naturally, you have to wonder if the 10% azelaic acid products you can purchase as a cosmetic would actually do anything for skin? They dissect the benefits of azelaic acid, discuss the formulation challenges behind this active, and ultimately how they would use a 10% azelaic acid product in their routine.
-
The chemists are gearing up for their 30 for 30 sunscreen challenge test! So naturally this is a great time to check up on some of the latest studies on sunscreens. We cover a large survey study on people’s sunscreen application habits (spoiler alert: it’s not great), an oil based vs water based cleanser study on sunscreen removal, a new J&J SPF50 vs SPF100 study, and an update on the ongoing studies on sunscreen’s impact on coral reef.

We’re back in the realm of plant extracts in skincare! This is a realm where real clinical data is quite sparse. So even simple questions like “does this extract work?” can be difficult to answer. In this episode, we discuss 3 plant ingredients with just enough interesting testing data for us to say “this is worth trying”.
-
Journeying into the more controversial ingredients, we first have to talk about petrolatum. One common question that we haven’t answered yet is, “Will petrolatum clog my pores?” There’s a surprising amount of data to discuss on this subject and after, we share best practices on using petrolatum in your skincare routine.

Taking a break from plant stuff and antioxidants, let’s talk about the newer exfoliator on the block, gluconolactone. Uniquely, gluconolactone has been tied to many skin benefits, being called hydrating, brightening, exfoliating, to maybe even…acne fighting? Ultimately we dissect the data to discuss what exactly gluconolactone does for skin and how it compares to the classic AHAs. Tune in to learn if gluconolactone deserves a place in your routine and how to best shop for this category!

In this episode, we’re continuing our Vitamin C series and are focusing on actives layering. Most of the questions we get are on whether or not you can layer certain actives with the very fussy ascorbic acid. We first review guidelines on the concept of layering, go through any evidence on ascorbic acid layering combinations, and finally discuss which pairings you should and shouldn’t worry about.

We’ve dedicated many episodes to Vitamin C, but there’s still more to cover! Recently, there have been a lot of Vitamin C launches and they are specifically for tackling hyperpigmentation. What makes this arena slightly confusing is that many of these products use Vitamin C derivatives. But, how helpful is Vitamin C in helping to tackle this very stubborn skin concern? And which Vitamin C molecule is best? We discuss all this and more. It’s time to go down the rabbit hole again!
