Dermalogica Precleanse is a lightweight cleansing oil designed to dissolve impurities from the skin. Its unique formula effectively removes sunscreen, excess sebum, and traces of makeup, preparing the skin for a deeper, more effective cleanse post-application. This oil-based preparation ensures that residue and buildup are gently yet thoroughly lifted from the skin surface, revealing a clearer complexion. It is an essential first step in any comprehensive skincare routine, especially beneficial for those who wear heavy makeup or live in urban environments with significant pollution exposure.
