A topical vitamin C antioxidant is an important daytime serum for protection against environmental free radicals. We offer several antioxidant day serum formulations for different skin types and concerns. For optimal day serum benefits, it’s important to select the products that address your primary skin concerns—whether fine lines and wrinkles, dryness, skin discoloration, blemishes, sensitive skin, or rough surface texture.

No. It’s important to apply your morning serum and give it a chance to be absorbed so the ingredients can provide your skin with their particular benefits. A daytime serum works to improve your skin throughout the day.

All SkinCeuticals day serum formulations can be used both in the morning and at night. (The only exception is our vitamin C antioxidant serums, which are only recommended for use as a daytime serum to protect the skin from environmental free radicals.)

Daytime serums should be applied after cleansing and toning. If using an antioxidant vitamin C day serum, this should be used before other morning serum formulations and paired with a broad-spectrum sunscreen. When applying multiple day serum products after your topical antioxidant, use thinner, more fluid formulas before moving on to thicker serums.
