Retinol is one of the best-known skin care ingredients on the market. Retinol has many potential skin care benefits, derived from vitamin A and is primarily used to treat mature-looking skin concerns as well as acne. Retinol does not remove dead cells as many other products do. Instead, small molecules that make retinol go deep beneath the outer layer skin. It helps neutralize free radicals which helps boost the production of elastin and collagen that can reduce the appearance of fine lines, wrinkles and enlarged pores. Also retinol treats sun spots and other signs of sun damage, uneven skin texture, melasma and other types of hyperpigmentation. People who use retinols may experience the following side effects dry and irritated skin, redness, itching, peeling skin. It’s better to consult your doctor before using a retinol product. Retinol is found in the form of tablets, capsules, cream, serum, injections. Also they should take into consideration that sun exposure could put you at risk for some of the same exact effects you’re using retinol for, such as age spots and wrinkles. To reduce such risks, wear a mineral-based sunscreen (an SPF of 15) whenever you plan to spend long periods outside. Avoid sun exposure while using retinols to avoid its side effects. It’s recommended for pregnant to avoid using retinol.
