Retinol is a superior anti-aging ingredient with decades of history. This vitamin A derivative helps, for example, in the treatment of wrinkles, hyperpigmentation, and excessive sebum production. There are many forms of retinoids, but what they all have in common is activating collagen production, brightening, and firming the skin.
Start using retinol gradually with a milder concentration, and remember to use sunscreen during the day, as retinol makes the skin more sensitive to sunlight. A more natural alternative to retinol is bakuchiol, which has similar effects to retinol. If your skin is sensitive, bakuchiol may be a better choice than true retinol.
