what does retinol serum do

Retinol serum is a skincare product that contains a form of vitamin A called retinol. Retinol increases skin cell production, unclogs pores, exfoliates the skin, and increases collagen production, which can reduce the appearance of fine lines and wrinkles, giving the skin a fresher, plump appearance. Retinol also helps neutralize free radicals in the middle layer of the skin, which can help reduce the appearance of wrinkles and enlarged pores. Retinol is primarily used to treat fine lines, wrinkles, sun spots, uneven skin texture, melasma, and other types of hyperpigmentation. It is also used to treat acne and related scarring. Retinol products are available over-the-counter, and stronger concentrations of retinoids are available by prescription. It is best to start using retinol slowly and gradually increase usage to avoid skin irritation.
