Retinoids (such as Differin, Acretin and Retin-A) reduce fine lines and wrinkles by increasing collagen production. It also stimulates the production of new blood vessels in the skin which improves skin tone. Additional benefits include fading age spots and smoothing rough patches of skin.
It takes 3 to 6 months of regular use before improvements in wrinkles are seen - best results take 6 to 12 months.
Because retinoids can cause skin dryness and irritation, doctors often recommend using them only every other day at first and then gradually working up to every night.
Apply sunscreen during the day because retinoids increase the sensitivity of the skin to sunlight. These medications must be used consistently to maintain their benefits.
You need a prescription.
