Dermatologist Note
Formulated at pH 5.0 — close to the skin's natural slightly acidic pH (4.5–5.5). Most cleansers are alkaline (pH 7–10) which disrupts the acid mantle and the skin microbiome. A pH-balanced cleanser helps preserve these natural defence mechanisms, particularly important before applying pH-sensitive actives like AHAs and BHAs.
Based on published clinical literature and dermatological research.
