Retinol
What it does
Retinol is a derivative of vitamin A and one of the most researched ingredients for the visible signs of aging — fine lines, rough texture, and uneven tone. It works by encouraging skin cell turnover and supporting collagen over time, so results build gradually with consistent use.
What to know
Retinol can cause dryness, flaking, or irritation when you first start, so it is best introduced slowly — a couple of nights a week, buffered with moisturizer, building up as skin adjusts. Use it at night, and always pair it with daily sunscreen, since it can make skin more sensitive to the sun. Important: retinoids are generally advised against in pregnancy and breastfeeding — check with your doctor first.
Commonly found in
Night serums, treatment creams, and targeted anti-aging products.
