Topical vitamin A-based medications called retinoids—essentially the most widely used and best-studied antiaging compounds—can reduce tremendous lines and wrinkles. Tretinoin, under the brand name Retin-A, was the primary retinoid. It was used as an pimples treatment within the Nineteen Seventies, but researchers later discovered that it also fades patches of actinic keratosis, evens out skin tone, and hastens skin cell turnover. does.
Retinoids reduce tremendous lines and wrinkles by increasing collagen production. They also stimulate the production of recent blood vessels within the skin, which improves skin tone. Additional advantages include fading of age spots and softening of rough skin patches.

Because retinoids could cause skin dryness and irritation, doctors often recommend using them only every other day after which regularly work as much as using them at night. Wear sunscreen throughout the day because retinoids increase the skin's sensitivity to sunlight. These medications should be used consistently to take care of their advantages.
Tretinoin (Retin-A, generic), tazarotene (Avage, Tazorac), and adapalene (Differin) are prescription retinoids. Adapalene can be available over-the-counter (in a 0.1% formulation vs. a 0.3% prescription version). Other retinoids are undergoing clinical trials.
In addition, there are several over-the-counter products available that contain retinoids, resembling retinol. Because they should not as strong (and thus less irritating), they should not as effective at reducing wrinkles as tretinoin; But they do improve the looks of photo-aging skin. Tretinoin could be used with alpha hydroxy acids (AHAs) for extra skin-smoothing effects.
