The INKEY List Advanced 0.2% Retinal Serum is a high-strength anti-aging facial treatment designed to visibly reduce deeper wrinkles, improve uneven skin texture and support firmer, smoother-looking skin. Formulated with 0.2% Retinal, a potent Vitamin A derivative, it targets advanced signs of aging, including established fine lines, wrinkles and loss of skin firmness. Retinal converts to its active form more directly than standard retinol, making it an option for experienced retinoid users looking to progress their routine. Clinically tested to deliver visible improvements in as little as one week, this targeted nighttime serum helps improve the appearance of skin smoothness, texture and overall signs of aging. Best suited to customers already familiar with retinol or retinoid skincare rather than complete beginners. Introduce gradually according to skin tolerance and avoid combining with other strong exfoliating actives in the same routine. Use at night after cleansing and before moisturizer. Apply broad-spectrum SPF during the day. Do not use during pregnancy or breastfeeding.
