A topical vitamin C antioxidant is an important daytime serum for daily use as it provides protection against environmental free radicals and pollution. 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 to the face 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 serum should be applied after cleansing and toning. If using an antioxidant vitamin C day serum, this should be used before other morning serum formulations. When applying multiple day serum products after your topical antioxidant, use thinner, more fluid formulas before moving on to thicker serums.

Morning serums should focus on protection and prevention. Antioxidant serums containing ingredients such as vitamin C and ferulic acid, like SkinCeuticals CE Ferulic®, help defend against free radicals from environmental aggressors like UV rays and pollution. Hydrating serums with hyaluronic acid, such as Hyaluronic Acid Intensifier Multi-Glycan, can help maintain moisture throughout the day.

Day serums for mature skin should target environmental protection, hydration, and visible signs of aging. Antioxidant serums with vitamin C and ferulic acid, such as CE Ferulic® or Phloretin CF, can help defend against daily oxidative stress, while firming or peptide-based serums like P-TIOX can help improve the appearance of elasticity and wrinkles. Adding a hydrating serum with hyaluronic acid, such as Hyaluronic Acid Intensifier Multi-Glycan or Hydrating B5 Gel, can help support smoother, plumper-looking skin throughout the day.
