Many adults have discovered that topical retinoid creams improve skin appearance by boosting collagen production and speeding all turnovers, which minimises lines and superficial wrinkles and produces smoother looking skin.
Prescription strength retinoids, which include tretinoin (Avita, retin-A, Tazorac)’ and adapalene (Differin), are also used to treat acne. All good, until you try to compound the benefit by another powerful anti-aging ingredient; glycolic acid.
Clycolic acid is an alpha-hydroxy acid (AHA) that speeds up skin renewal. It is found in many over-the-counter products. Unfortunately, they cancel each other out. One ingredient makes the other inactive.
BETTER WAY: Space out the use of retinoid and products with glycolic acid. Use them on alternating days. e.g some dermatologists recommend using a retinoid only at night (the recommended time since retinoid are sun-sensitive) and a glycolic acid only in the morning. Ends
