What is Retinol?
Also known as: Retinol, A vitamini, Retinoid
Short answer
Retinol is a vitamin A derivative (retinoid) anti-aging active; it is one of the best-proven ingredients for wrinkles, acne and dark spots. It is effective but can irritate and should not be used in pregnancy. The EU limited retinol to 0.3% in face products.
What is Retinol and what does it do?
Retinol is a vitamin A derivative that converts to retinoic acid in the skin. Because it speeds cell turnover, it has been used for decades for wrinkles, fine lines, acne and dark spots, and is one of the best scientifically proven actives.
Benefits
By supporting collagen it reduces fine lines, smooths skin texture, improves pores and acne, and lightens spots and uneven tone. It is one of the few actives that makes a visible difference with regular use.
What to watch for
At first it can cause redness, dryness, flaking and stinging (the retinization period). It makes skin more sun-sensitive, so it is used at night and daytime sun protection is essential. It is advised not to use it in pregnancy or breastfeeding. The EU Cosmetics Regulation limits retinol to 0.3% in face products and 0.05% on the body.
How to use it
Start low and 2-3 nights a week, increasing frequency as skin adjusts (the 'go slow' rule). Use a pea-sized amount on dry skin; a moisturizer on top reduces irritation. Always use sunscreen during the day. Do not use if pregnant.
