ZO Skin Health Retinol Skin Brightener is a powerful treatment designed to brighten the skin and improve its texture. Available in three strengths (0.25%, 0.5%, and 1%), this retinol-based formula helps reduce the appearance of fine lines, wrinkles, and discoloration while promoting skin cell turnover for a smoother, more even complexion. The gentle 0.25% formula is ideal for sensitive skin or first-time retinol users, while the 0.5% and 1% formulas provide more intensive results for more resilient skin. Regular use reveals a brighter, more radiant complexion with improved skin tone and texture.
