Zyderma HS – Gentle Foaming Cleanser (Refillable) 5 FL OZ / 150ml

This delicate and well-balanced formula with its rich long-lasting foam provides a gentle and effective cleansing for a variety of skin types, while respecting the barrier function of the epidermis. The formula is a synergistic combination of delicate surfactants derived from oat (Avena Sativa) lipoamino acids designed to selectively cleanse impurities from the skin without stripping the lipid barrier. This sebo-normalizing activity helps reduce the appearance of irritation associated with traditional cleansers while leaving the skin’s protective barrier intact.
