Name for the entire vitamin A molecule. Retinol is a powerhouse ingredient that has value for skin on several fronts: It’s a skin-restoring, wrinkle-smoothing, firming ingredient and an antioxidant, allowing it to improve a variety of skin concerns, most related to visible signs of aging.
Packaging is a key issue, so any container that lets in air (like jar packaging) or sunlight (clear containers) just won’t cut it. Lots of retinol products come in unacceptable packaging; these should be avoided because the retinol will most likely be (or quickly become) ineffective. Look for opaque, airless, or air-restrictive packaging.
Many consumers are concerned about the percentage of retinol in anti-aging products such as serums or moisturizers. Although the percentage can make a difference (especially if it’s too low), it’s not helpful in understanding how a retinol product will benefit your skin. Far more important is the delivery system, packaging, and the other ingredients present with the retinol.
Using a product with a range of anti-aging ingredients plus retinol is far more valuable for skin than using a product with only a supposedly high percentage of retinol. Skin needs far more than any one ingredient can provide, however great that one ingredient may be. See our article on this topic for detailed information.
There are several myths about using retinol with other anti-aging ingredients or products, such as those with vitamin C or exfoliants like glycolic acid. See our article on this topic to learn what the research has shown to be true.
