Derived from Vitamin A, retinol is a powerful ingredient that has been used in the treatment of acne and aging. A form of retinoid, retinol is one of the most powerful over-the-counter products you can get, making it accessible for any skin concern that would benefit from its effect on the skin. Rather than simply exfoliating the surface of the skin, retinol penetrates the outer layer, increasing elastin and collagen in the middle layer.
Since milia is formed by dead skin that is trapped underneath the surface of the skin, a retinol will help penetrate the top layer, exfoliating away the bumps and giving smoother skin. Retinols increase the cell turnover of your skin, preventing any excess shed skin from staying trapped. When it comes to powerful exfoliation, the concentration of your retinol is essential to achieving the best results.
The Sunday Riley A+ High-Dose Retinol Serum has a 6.5% solution of retinoid, staving off congested skin. An extremely potent concentration of retinol, it’s balanced by soothing honey and cactus extract.
