This VitaminC serum contains hyalyronic acid, retinol and collagen. Retinol is great for crow's feet, wrinkles and even acne!!! I have acne issues. My doctor prescribes me face cream with retinol. Collagen helps your skin look younger !! Hyalyronic acid is great for wrinkles too .
I haven't been able to use this long enough to give a great review. I don't have complaints. There's no red spots or any pain
