Instead of getting bogged down by marketing fluff, we dive deep into the real metrics of sunscreen performance: initial application speed, the science behind "watery breaks," and how a product's long-term finish affects different skin types. Listeners will walk away knowing exactly how to spot uneven film formation, navigate the nuances of water and friction resistance, and decode why certain formulas cause eye irritation or pilling so they can find their perfect, reliable daily match. #skincarescience #skincare #skincareroutine #sunscreen

We are deep in sunscreen season, but unfortunately, it is also fear-mongering season. In this episode, we take a scientific look at prominent clean beauty advocacy voices like EWG and the Yuka app to untangle the science from the marketing fluff. We pull back the curtain on how these platforms analyze formulations, revealing why their extreme stances and rigid rating systems often lead to massive inconsistencies, misguided consumer fear, and ultimately, unsafe choices for your skin. By walking you through real-world formulation realities—from the stabilization challenges of zinc oxide to the actual toxicological safety profiles of chemical filters like octocrylene and vital preservatives like phenoxyethanol—we give you the context needed to tune out the noise. Tune in to ground yourself in cosmetic chemistry, find peace of mind, and gain the confidence to choose formulas that actually protect your skin daily without the unnecessary anxiety.

We are starting of this series with tinted sunscreens. Navigating this category can feel like an existential crisis because these formulas are highly dependent on specific skin types and coverage needs. In this episode, we categorize this year's contenders by pigment level—ranging from completely sheer fluids to high-coverage, foundation-like hybrids, while analyzing the formulation realities behind heavy textures, solvent loads, and the myth of the "universal tint".

#177) We must talk about IRON OXIDES! May 28, 2026

We are officially diving into the sunscreen segment to break down a burning, highly technical question for anyone tackling stubborn dark spots: is iron oxide a non-negotiable must-have for your hyperpigmentation routine?

You will learn how these products perform on different skin types—from "sticky and drying" textures to clinical-grade results—so you can decide which formulas are worth your routine and which are just "science-flavored" fillers.

#173) How About Exosomes in Skincare Now? (A 2026 Update) Apr 16, 2026

Exosome is that $500 buzzword that's not going anywhere anytime soon. The claims have only gotten broader from healing, skin regeneration, eczema, anti-aging, to even alopecia. In this episode, we provide an update on any new data since our last deep dive last year. We discuss how these tiny lipid nanovesicles—ranging from 30 to 200 nanometers—function as "biological mail" that triggers collagen synthesis and other regenerative pathways. But do the theories really convert to proven topical benefits? We also tackle one of the most important things you should know about exosomes - sourcing. Does it matter if your exosomes come from humans, plants, or bacteria? And what sort of skin benefits could exosomes provide...if any.

In this episode, we are diving deep into the retinal (retinaldehyde) landscape to see how current market offerings stack up. Following our technical breakdown of retinol versus retinal, we shift our focus to real-world testing of popular formulations from Krave Beauty, Prequel, Celimax, and Medik8. We examine the scientific validity of concentration ranges—from the entry-level 0.05% to the more intense 0.24%—and discuss how different textures and price points impact the user experience for various skin types. Whether you are a retinoid rookie or a seasoned pro, we provide the detailed assessment on the data to find the right one for your particular skinario.

#153) The Science Behind Sulfur for Acne & Skincare Oct 01, 2025

We take a deep dive into the science behind Sulfur, a very old and historically prevalent ingredient for acne. We discuss its nonmetal clay origins and characteristic scent, often described as rotten eggs , or like "if a clay farted". The episode covers its classification as an OTC acne ingredient , its proposed catalytic and oil-absorbing mechanisms , and the challenges in its topical formulation, such as particle size. We also look at old-school research, including a study on 10% Sulfur + 4% Niacinamide drying lotion , and offer realistic expectations: Sulfur is best used as a spot treatment for quick fixes, not for long-term overall breakout reduction

This is a wild category of products. Unlike the CE Ferulic dupes, the range is far and wide in between! From texture critiques (why so sticky, Elf?) to actives breakdown, we decode the labels and share which formulas we’d choose — and which ones barely count as a vitamin C serum at all.

#139) Which Vitamin C (Ascorbic Acid) Serum is Better? Water or Anhydrous? May 13, 2025

Vitamin C, ascorbic acid, is famously known as the only rigorously tested antioxidant for age prevention. Yet this active is also notoriously known for its quirky characteristics in the classic CE Ferulic serum format. This unstable hot dog water has often generated concerns for using it long term. In this episode, the chemists discuss ascorbic acid’s stability and compare vitamin C in water-based formulas vs. anhydrous formulas to see if there’s a better format for this finicky active.

#137: 5 KBeauty Cleansing Oils H2H Apr 29, 2025

We discuss our thoughts on the texture and use experience from both the oily skin and dry skin perspective.

#136: Can You Just Use Water to Cleanse Your Face? Apr 28, 2025

On the topic of cleansers, a lot of the questions the chemists get are about the cleansing routine. One of the common questions is, “Can you just use water to cleanser your face?” The great thing is, this scenario has actually been tested (which is very rare). The chemists discuss the findings and what things to consider if you happen to be using just water to rinse your face. An unusual deep dive, but hopefully interesting and satisfying for those who’ve ever wondered.

#135: 4 Affordable Drugstore Moisturizers H2H Apr 15, 2025

We discuss our thoughts on the texture and use experience from both the oily skin and dry skin perspective.

#132: Should you use ectoin in your routine? Mar 26, 2025

Many of you asked about ectoin so the chemists went down the research rabbit hole. Ectoin is a new kid on the block with some surprising data in the skin barrier and hydration realm. The chemists talk about what it is, what it does for skin, and whether or not it’s better than niacinamide.

#131: 5 K-Beauty Toner Pads H2H Mar 18, 2025

We discuss our thoughts on the texture and use experience from both the oily skin and dry skin perspective.

#130: Can You Shrink Pores with Skincare? Mar 11, 2025

When strategizing how to tackle pores, the science is about as random as the skincare landscape. The chemists tackle the biology, the ingredients, and the skincare to try to make sense of what steps can actually make a meaningful difference to help reduce pore size. Can “glass”, “egg”, poreless skin actually achievable?

#123: Estriol & Estradiol Skincare - Do They Work? Dec 17, 2024

As a follow-up on last week’s episode on skincare for certain age groups, this week, let’s dive into estrogen-based skincare, in particular creams with estradiol or estriol. This prescription skincare realm aimed to treat peri and post-menopausal skin issues like irritation, redness, and dryness. So! Do they work? Are there other benefits beyond skin barrier care?

#122: Skincare Tips by Age Group: Teens, 20s, 30s, 40s, and 50+ Dec 12, 2024

#119: Which SPF Lip Balm is Best? Nov 04, 2024

After a nice break from sunscreens, we had some time to dabble in lip SPF products. It turns out our lip skin actually has a lot less natural protection from both sun and dryness than the rest of our body. Thus, it only makes sense that having a good lip SPF (or two) is important to have handy. We tried 12 lip SPFS of various types and various price points and share all of our findings! The taste of some of these left quite a lasting impression.

#118: Are Peptides in Skincare Worth It? Oct 29, 2024

Today we’re going to attempt to tackle the vast landscape of peptides! It’s a big topic but sadly without a lot of clarity. So let’s nerd out with us on just what peptides are, how they work on skin, what skin concerns they’re good for, and decode a few top peptide products.

#117: Hydroquinone and Some Comparison Actives Oct 22, 2024

After listening to this podcast long enough, you’ll probably get a sense that good testing data is sparse so we inevitably have to work with what we have! With the recent US ban of OTC hydroquinone products, it's worth noting that a notable few actives have done testing in direct comparison to hydroquinone. Though more testing is always needed, direct comparison studies are considered rare and top-tier in our books. In this episode, let’s review why hydroquinone is so prolific and discuss actives that have actually been tested in direct comparison to hydroquinone.

#116: Is Arbutin A Good Hydroquinone Alternative? Oct 14, 2024

This is a bit overdue! Arbutin is a hyperpigmentation active with a reputation as a hydroquinone alternative. So today we’re tackling all the major questions around arbutin: Does it convert to hydroquinone on skin? Is it even a good hyperpigmentation active?

#114: What's the Deal With Exosomes in Skincare? Sep 24, 2024

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.

#113: Do Acne Patches Work? Sep 16, 2024

We're wrapping up our acne series with a deep dive on acne patches. These face stickers often get tied to some pretty enticing claims like absorbing excess sebum and rapidly healing pimples. We discuss the science behind these mystical patches, what they actually do to acne lesions, and what are their real benefits. Finally, we end on our experiences trying 5 different acne patches on the market. Enjoy!

#112: Does Any of the Plant Stuff Work for Acne? Sep 09, 2024

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?

#111: How Much Benzoyl Peroxide Should You Actually Be Using? Aug 26, 2024

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.

#110: Is salicylic acid a MUST in your acne routine? Aug 19, 2024

Salicylic acid is probably the most common active ingredient you’ll run into when putting together your acne routine. But is it actually a must have? What kind of acne can it actually treat? In this episode, we dive into a few key clinical studies that look at just what 2% salicylic acid really bring to your routine.

#109: Are Collagen Supplements a Scam? Aug 12, 2024

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.

#108: The Best of 30 for 30 Sunscreen Challenge Pt. 2 Aug 05, 2024

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. In part 2, we talked about our thoughts on baby sunscreens, international sunscreens, things we’d do differently in the future, and… pangolins? Let’s wrap the sunscreen series!

#107: The Best of 30 for 30 Sunscreen Challenge Pt. 1 Jul 29, 2024

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. In part 1, we discuss what factored into our ratings and why. We then go through our “0 star” ratings and why they were so painful. 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.

#106: Should You Stop Using Glycolic Acid in the Summer? Jul 22, 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.

#105: Which Toners Should You Use? Jul 15, 2024

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!

#104: Does Tranexamic Acid Have Any Benefits for Skin? Jul 08, 2024

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.

#103: Should You Be Using the Azelaic Acid Derivative Instead? Jul 01, 2024

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!

#102: Does 10% Azelaic Acid Do Anything for Skin? Jun 17, 2024

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.

#101: Do You Need an Oil Cleanser to Remove Sunscreen? A Sunscreen Update! Jun 10, 2024

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.

#100: The 100th Celebration! Chemists' (true) Confessions Jun 03, 2024

We’ve reached the 100th Episode! This week we’re going down memory lane ranking our top 5 podcast moments and our favorite skincare science. We also decide to reveal some true chemist “confessions”. We share what popular ingredients we might not be fully on board with and even what skincare steps we forget. Time for some fun!

#99: Plant Stuff That Should Be On Your Radar May 27, 2024

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”.

#98: Does Petrolatum Clog Pores May 13, 2024

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.

#97: How Does Gluconolactone Compare to AHAs? May 06, 2024

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!

#96: What Actives Can You Layer With Vitamin C? Apr 29, 2024

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.

#95: How Good is Vitamin C For Hyperpigmentation Really? Apr 22, 2024

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!

#94: Is Resveratrol Better Than Vitamin C? Apr 15, 2024

We’ve encountered many skincare users who have discovered that the Vitamin C realm is just not their cup of tea and neither is it for their skin. Enter resveratrol! We discuss what resveratrol is, its antioxidant capabilities, and why despite the amount of data, we consider this a solid option as a non-Vitamin C antioxidant replacement. You’ve been warned, we get nerdy here, but lets go down the rabbit hole shall we?

#93: What Benefits Does Kojic Acid Have For Skin? Apr 08, 2024

There’s a lot of rice-based ingredients and rice-adjacent ingredients in skincare. They can span from functional ingredients such as waxes and thickeners to exotic actives like the very famous Pitera. Amongst all of these ingredients, there’s one isolated active compound that we believe deserves some attention and that is kojic acid. This ingredient is a byproduct of the sake fermentation process and happens to have some solid data as a hyperpigmentation-fighting active. So let’s dive in!

#92: What Does Centella Asiatica Actually Do For Skin? Apr 01, 2024

Centella Asiatica (aka cica) has continued to reign as a trendy plant-based active. For good reason! With origins as a wound healing ingredient, the research behind centella asiatica as a skincare ingredient has really grown. We go through the research update and talk about its benefits as a skin soother and possible anti-aging ingredient. Finally, we walk through how to shop for centella asiatica and ultimately how to hunt for the good stuff: madecassoside & asiaticoside.

#91: If There's Glycolic & Lactic Acid, Why Should We Use Mandelic Acid? Mar 25, 2024

In the world of AHAs, mandelic acid feels like that forgotten child. We always talk about the golden child, glycolic acid, as well as the more gentle exfoliator, lactic acid. So when would a person need mandelic acid in their life? We go through the data and discuss who it’s good for, how much you should be using, and how to shop for this unique AHA.

#90: Why is Ginseng in Skincare? Mar 18, 2024

Ginseng is definitely one of those alluring, almost magical ingredients that not only gets touted as a cure-all but almost as a skin cure-all as well. This root has been linked to a wide array of skincare benefits such as being an antioxidant, anti-inflammatory, and anti-aging. But is there any merit to these claims? We discuss the science and just how helpful ginseng can be to your skincare routine.

#89: Can You Have Too Much Niacinamide? Mar 11, 2024

Niacinamide is EVERYWHERE in the skincare world, but for good reasons. It’s a jack-of-all-trades type of molecule that has actual clinical evidence that ranges from improving skin barrier function, reducing sebum production, to brightening hyperpigmentation. But in recent years products now have way more niacinamide than ever before. So let's review some of niacinamide’s most famous clinical tests and answer the question “is there such thing as too much niacinamide?”

#88: Can Urea Replace Your AHAs? Mar 04, 2024

Urea has surprisingly been creeping up the ranks in skincare ingredient awareness.
