Prescription-strength retinol products may cause more side effects than the over-the-counter strength.
Retinol is proven to improve mottled pigmentation, fine lines and wrinkles, skin texture, skin tone and color, and your skin's hydration levels. This is the only form of vitamin C that you should look for in your skin care products. There are many skin care products on the market today that boast vitamin C derivatives as an ingredient (magnesium ascorbyl phosphate or ascorbyl palmitate, for example), but L-ascorbic acid is the only useful form of vitamin C in skin care products. With age and sun exposure, collagen synthesis in the skin decreases, leading to wrinkles.
