Retinol is one of the best-known skin care ingredients on the market. An over-the-counter (OTC) version of retinoids, retinol is derived (made from) vitamin A and is primarily used to treat mature-looking skin concerns as well as acne.

That said, retinols are not the same products as prescription retinoids, which are more powerful. However, retinol is still the strongest OTC version available, compared with OTC retinoids such as retinaldehyde and retinyl palmate.

Retinol has many potential skin care benefits, but there are side effects to consider, too.

Curious about whether retinol could be a beneficial addition to your skin care routine? Learn more about this key ingredient below.

etinol is a type of retinoid, which is made from vitamin A. It does not remove dead skin cells, as many other products for mature skin do. Instead, the small molecules that make up retinol go deep beneath the epidermis (outer layer of skin) to your dermis.

Once in this middle layer of skin, retinol helps neutralize free radicals. This helps boost the production of elastin and collagen, which creates a “plumping” effect that can reduce the appearance of:

fine lines
wrinkles
enlarged pores
