SkinCeuticals blemish-targeted serum formulated to address adult acne while improving visible signs of aging. This oil-free, exfoliating serum combines LHA (lipo-hydroxy acid), salicylic acid, glycolic acid and dioic acid to help unclog pores, reduce excess sebum production and promote cellular turnover. The formula helps clear and prevent comedones, reduce the appearance of post-acne blemishes and improve skin texture, fine lines and uneven tone. Intended as a targeted treatment, apply to cleansed, dry skin according to product directions and avoid the immediate eye area. Because it contains multiple chemical exfoliants, concurrent use with other strong exfoliating products or prescription retinoids should be done cautiously and under professional guidance. Sun protection is recommended during use due to increased photosensitivity. Suitable primarily for oily, acne-prone and combination skin types concerned with both active breakouts and early signs of aging; those with very sensitive, compromised or heavily irritated skin should consult a dermatologist before use. Reduces blemishes and breakouts, unclogs pores and improves visible signs of aging. 2% dioic acid + 1.5% salicylic acid help reduce excess sebum and unclog pores to fight blemishes. Formulated for oily and combination, acne-prone adult skin to reduce blemishes and decongest pores. Lightweight, fast-absorbing, oil-free serum with a smooth, non-greasy mattifying finish. Dermatologist-tested, non-comedogenic formula targets breakouts while improving signs of aging. important information This product is for external use only
