How does papain exfoliate skin and why is it in the formula?

Papain is a proteolytic enzyme naturally occurring in papaya fruit that breaks down the keratin proteins in dead, hardened skin cells, effectively digesting surface buildup without any mechanical scrubbing action required. This makes it a particularly valuable ingredient for people who want effective exfoliation without the risk of micro-tears or irritation that can come from aggressive physical scrubs. In the Light Skin Peel, papain works alongside salicylic acid to provide both enzymatic and chemical exfoliation in one formula, addressing different aspects of cellular buildup at the same time. Papain also has natural anti-inflammatory properties, which helps keep the exfoliation experience calm and comfortable even for skin types that tend toward sensitivity or blemish-prone conditions.
