2 What Is Retinol A Serum?
Retinol A serum is a skincare product made from a form of Vitamin A called Retinol. It is one of the most researched and proven ingredients in dermatology. Retinol increases skin cell turnover, boosts Skin Health, increases collagen production, reduces pigmentation, and keeps pores clean.
Retinol A is often confused with “retinoids,” but retinol is the milder, over-the-counter version that is safe for long-term use when applied correctly.
Common strengths include 0.1%, 0.2%, 0.5%, and 1%.
Typical ingredients added to retinol serums:
Niacinamide
Ceramides
Vitamin E
Peptides
These help reduce dryness and irritation while enhancing the benefits.
