Elelaf Education Desk

The Education Desk writes the foundational material — skin anatomy and physiology, barrier function, pH and the acid mantle, how to read an INCI list, how to think about skin type instead of guessing one. The aim is reader literacy: when someone understands TEWL or what stratum corneum actually does, they make better decisions about everything downstream. We pull from textbook physiology (Wikoff, Baumann, Bouwstra) and pair it with published clinical data, not Instagram explanations. Every foundational piece is written so it stays useful for years — and updated when the underlying science shifts (the niacinamide percentage debate, the bakuchiol RCTs, the slugging-on-active-acne discussion).
