Medik8 Crystal Retinal 20 Serum 30 ml is an advanced anti-aging treatment formulated with a high concentration of retinaldehyde — a next-generation Vitamin A derivative recognized for delivering visible improvement in texture, tone, and aging signs. At a 0.20% strength, this serum is one of the most powerful in the Crystal Retinal range, intended for experienced retinal users seeking significant results.
Retinaldehyde works by accelerating cellular turnover and converting efficiently to retinoic acid upon application, helping to promote smoother skin, reduce the appearance of fine lines, and enhance overall radiance. The Crystal Retinal delivery system is uniquely designed to maximize effectiveness while helping balance tolerability compared with traditional retinoids.
Crystal Retinal 20 is ideal for those who have already built tolerance to lower retinal strengths and are ready to advance to more targeted anti-aging results.
