A topical vitamin C antioxidant face serum is an important daytime facial serum for 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. Incorporating hyaluronic acid serum into your day serum can significantly enhance skin hydration and elasticity, offering a plump, youthful appearance.

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 as part of your skincare routine.

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, enriched with fruit oil and wood oil, 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, ensuring the xanthan gum in the formulation enhances the texture and consistency for smooth application.
