How does it work?
Retinol is a form of retinoids, that is made from vitamin A. Unlike every other anti-aging and acne [1] product that kills aging cells, retinol works by going beneath the epidermis [2] (outer layer of skin) to the inner layer of the skin (dermis) and acting there.
They go deep into the skin and neutralize free radicals and increase the surface skin cell turnover, making new cells grow underneath. They impede the degrading of collagen [3] and thicken the deeper layer of the skin.
Retinol is also used to treat several serious acne and other scarring conditions. It is used to keep pores unclogged by creating comedolytic agents to help impede the production of comedones or blemishes. In some cases, the dermatologist may recommend an antibiotic with retinol treatment. You should know that it can take over six weeks before improvements start to show.
Retinol is also commonly used to keep the skin adequately hydrated. Weak exfoliating effects help to kill dead skin cells that may lead to dryness. People with oily skins can use retinol because it helps to control the production of sebum [4] in pores.
Retinol is the most common type of retinoids and it is weaker than most retinoids. Retinols are usually added to over-the-counter drugs.
When using retinol, you should exfoliate, clean, and tone your face. Then use a small, pea-sized amount of retinol to dry skin. You should avoid applying retinol to the eyes and mouth. You can use a brightening product, followed by serums or night creams.
Retinols can be very drying, so it is important to use them with an effective moisturizer, so the kin can remain hydrated.
