Safety Ingredients

A fruit enzyme that helps exfoliate and soften skin

A fruit enzyme, such as bromelain from pineapple or papain from papaya, helps exfoliate and soften skin by breaking down and dissolving dead skin cells. This gentle exfoliation process reveals a smoother, brighter complexion and promotes cell turnover. Suitable for all skin types, it offers a natural and less abrasive alternative to traditional chemical exfoliants.
