Pharmaceris Acipeel Depigmenting Serum is a specialized night treatment formulated to address skin hyperpigmentation and uneven tone. The serum uses a unique complex of three acids and vitamin C to regulate melanogenesis and reduce existing dark spots while preventing new ones from forming. The serum contains mandelic acid that inhibits tyrosinase and reduces melanin synthesis, salicylic acid that exfoliates dead skin cells, and citric acid that has a depigmenting effect. It's suitable for treating various types of hyperpigmentation including freckles, age spots, post-acne marks, and melasma. The formula is well-tolerated even by sensitive skin. For best results, apply nightly to cleansed skin on affected areas, avoiding the eye and mouth area. Temporary skin redness may occur as a natural reaction. The product should be used as part of a complete skincare routine including appropriate sun protection during the day.
