Avoid combining it with vitamin C, as this may cause irritation. Although not photosensitizing, retinol has an exfoliating action on the skin, making it more sensitive to the sun.
The right reflex? Apply your retinol-based skin care product in the evening, and don't forget your sun protection during the day, summer or winter. Our recommendation: use SPF-containing products from the CELLULAR'SUN and UNI'PERFECT collections. It's essential for beautiful, healthy skin.
