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...
