Ingredient of the Month: Retinol
Retinol is a cosmetic grade version of Vitamin A, and while most people have heard of prescription retinoids like tretinoin (Renova, Retin-A), adapalene (Differin), and tazarotene (Tazorac), what most people don’t realize is that stronger isn’t necessarily better. For nonprescription retinoids, more important than the percentage alone is the delivery system and package stability (retinol degrades heavily in the presence of oxygen and light), and the other ingredients paired with the retinol. A lower concentration in a stable and side effect-free formula will produce powerful results over time without the dryness, redness and flaking some people experience with prescription formulas.
The best way of getting all the cell renewing benefits of retinol without the prescription-level side effects is to use an over-the-counter version like Rodan + Fields® ANTI-AGE Night Renewing Serum.
