ISDIN CEUTICS RENEW GLICOISDIN 25 Intense Gel is a professional-strength exfoliating treatment formulated with 25% glycolic acid to accelerate skin renewal and improve texture. This 50g gel penetrates deeply to dissolve dead skin cells, revealing smoother, brighter skin beneath. Ideal for those seeking visible results in reducing fine lines, uneven tone, and surface imperfections, this intense formula works to enhance skin radiance and promote a more refined complexion. The concentrated glycolic acid concentration makes it suitable for experienced users of chemical exfoliants. Apply as directed to clean, dry skin. Due to its potency, start with minimal frequency and gradually increase usage as skin builds tolerance. Always follow with sunscreen during daytime use, as exfoliated skin requires enhanced UV protection. Perfect for a targeted weekly treatment or as part of a professional skincare regimen designed to restore youthful luminosity and smoothness.
