How to Use a Vitamin C Serum

Cleanse Your Skin

Before you apply your vitamin C serum, make sure your skin is freshly cleansed and towel-dried. This breakdown of cleanser formulas will help you find a formula that best suits your skin type.

Apply the Vitamin C Serum

You can apply your vitamin C serum morning or night, according to the product’s instructions. Vitamin C is an antioxidant, which means it neutralizesfree radicals, so it can be especially beneficial to apply your serum in the morning. 

Follow With Moisturizer and/or Broad-Spectrum SPF

If you apply your vitamin C serum in the morning, be sure to follow it with both a moisturizer and a broad-spectrum sunscreen to shield your skin from the sun. If you apply it at night, skip the SPF and just apply your moisturizer.
