Overview

Medik8 Crystal Retinal 3 Serum 1oz is a gentle yet effective nighttime serum that promotes smoother, more youthful skin. This serum contains retinaldehyde, a potent form of vitamin A known for its anti-aging properties.

Key Ingredients & Benefits

The key ingredient in this serum is retinaldehyde (0.03%), a less irritating form of vitamin A that helps accelerate skin renewal. It effectively reduces signs of aging such as fine lines and uneven texture. Additionally, the serum contains hyaluronic acid, which deeply hydrates the skin, leaving it feeling plump and smooth. Vitamin E adds antioxidant protection, safeguarding the skin from environmental stressors and supporting overall skin health. This combination of ingredients provides a potent yet gentle anti-aging solution.
