Antioxidants protect the skin and other cells by fighting free radicals. These unstable atoms can break down cells and are linked with a number of illnesses, as well as signs of aging.

Antioxidant serums are skin care products. They frequently contain any of the following antioxidants:

The best antioxidant serums may help prevent and repair skin damage caused by an excess of free radicals.

More specific possible benefits include:

  • protecting the skin from damage due to UVA and UVB radiation
  • preventing redness
  • helping the skin repair itself
  • brightening the skin tone
  • calming irritation
  • minimizing irritation from acne
  • supporting the protective effects of sunscreen

A 2017 study notes that anyone using topical antioxidants still needs to obtain antioxidants from fruits and vegetables in the diet.

Antioxidant serums can carry risks. For example, they may interact with other medicated products or irritate sensitive skin. The American Academy of Dermatology Association recommends trying a little bit of antioxidant serum on the wrist first.

If no irritation develops after applying the serum to the wrist twice a day for 4–5 days, a person can lightly apply the serum to the face and use more product as needed, gradually.

How to use them

Manufacturers typically recommend applying a serum after cleansing the face and before moisturizing it. To reduce associated risks, read the manufacturer’s directions before trying any product.

Anyone shopping for an antioxidant serum might look for a product with the following characteristics:

  • well-researched ingredients, such as vitamin E
  • a variety of antioxidants
  • secure packaging to keep out UV light and air
  • little or no alcohol, which can dry out the skin
  • a reasonable price, as a high price does not necessarily translate into high quality
