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 Products Discussed this 2025 Podcast Season *a small portion of your purchase through these links goes to feeding a chemist. https://shopmy.us/collections/1280514 Recommended 30 for 30 Sunscreens 2025 *a small portion of your purchase through these links goes to feeding a chemist. https://shopmy.us/collections/1766357 Product Shoutout: Blank Slate Gentle Gel Cleanser https://chemistconfessions.com/products/blank-slate-cleanser Enrichment Content: Sunscreen Layering Guide https://www.youtube.com/watch?v=IQ0Dlb0WXvc Do We Absorb Sunscreen Filters into Our Bloodstreams? https://chemistconfessions.com/blogs/controversy-corner-do-we-absorb-sunscreen-filters-into-our-bloodstreams Follow us: IG: / chemist.confessions INTERWEB: https://chemistconfessions.com/ TIKTOK: https://www.tiktok.com/@chemistconfes...

Victoria recently decided to commit to 100 days of double cleansing on her oily, acne-prone skin. In those 100 days, she tests 10 cleansing oils and 10 gel cleansers. They discuss their likes, dislikes, and surprise discoveries amongst these formulas. Ultimately, the chemists’ goal in this experiment is to answer the question, “Should you be double cleansing every day?” Additionally, they hope that in this experiment they can help pinpoint what traits to look for in a good oil cleanser and gel cleanser.

This is a wild category of products. Unlike the CE Ferulic dupes, the range is far and wide in between!

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.  Products Discussed this 2025 Podcast Season *a small portion of your purchase through these links goes to feeding a chemist. https://shopmy.us/collections/1280514 Product Shoutout: Aquafix Hydrating Water Gel https://chemistconfessions.com/products/aquafix-hydrating-water-gel Enrichment Content: Podcast Ep - Which Vitamin C Derivative is Better? https://www.youtube.com/watch?v=b96PX4L6hsQ&t=82s Results of our CE Ferulic Dupe Test - Pt. 1 https://chemistconfessions.com/blogs/5-skinceuticals-vitamin-c-dupes-put-to-the-test Follow us: IG: https://www.instagram.com/chemist.confessions/ INTERWEB: https://chemistconfessions.com/ TIKTOK: https://www.tiktok.com/@chemistconfessions?lang=en Skincare questions for the podcast?

It’s finally getting warmer and this means that we’ve already started testing our 2025 #30for30SunscreenChallenge tests! So this feels like a great time to do a special sunscreen news roundup episode. In this episode, we discuss why you can’t buy Asian sunscreen formulas as easily anymore, what tariffs might mean for the sunscreen landscape, and interesting studies on sunscreen application. Oh! And in case you’re curious, we also cover all the factors the UV index considers to help you make an informed decision on your sun protection of the day.

In 2025, the chemists want to tackle both the science and practical application of skincare. Following our cleanser science episode, we tested 5 of the topselling Kbeauty cleansing oils so you don’t have to, which include: Skin1004, Beauty of Joseon, Anua, Ma:Nyo, and Haru Haru. We discuss our thoughts on the texture and use experience from both the oily skin and dry skin perspective. 

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.
