The Cosmetic Chemist's Guide to Exfoliating Black & Brown Skin

Are you exfoliating too much? For Black & Brown skin, more exfoliation doesn't mean better skin. In fact, over-exfoliation can lead to irritation, a damaged skin barrier, and post-inflammatory hyperpigmentation (PIH) that lasts far longer than the rough texture you were trying to fix. In this science-backed episode, we explain how cosmetic chemists think about exfoliation—and why the goal isn't the strongest acid, but the minimum effective dose. You'll learn: • How exfoliation actually works • AHAs vs BHAs vs PHAs • Glycolic acid, lactic acid, mandelic acid, salicylic acid and urea explained • Why darker skin needs a different exfoliation strategy • How over-exfoliation causes more hyperpigmentation • How skin pH affects exfoliation • How often you should exfoliate • Which exfoliant is best for your skin type Whether you're dealing with rough texture, clogged pores, acne, or uneven skin tone, this episode will help you exfoliate safely using evidence—not trends.
