The 9 Best Antioxidant Serums That Actually Work

Ashley Batz / Bustle

If cleansers and moisturizers are the bread and butter of the skincare world, the best antioxidant serums are like gourmet cheese and meats that pull the entire sandwich together. Questionable metaphors aside, antioxidants truly are the stars in your skincare regimen: they have the power to protect your skin from the harmful effects of pollution by neutralizing the free radicals in pollution that can cause skin damage. And, of course, serums with sunscreen shield your skin from the dangers of UVA and UVB rays, which can cause skin cancer, as well as hyperpigmentation and fine lines.

Antioxidant serums have concentrated active ingredients and are best to use in the morning, after your cleanser and toner and before moisturizer and sunscreen. Some even deliver a layer of protection that shields against infrared radiation, which penetrates even deeper than UV rays. To put it bluntly: the combination of a powerful antioxidant plus an additional sunscreen on top equals sun protection the likes of which you've probably never known.

The best antioxidant serums also contain hydrating ingredients like hyaluronic acid, algae, and vitamins, while others help protect your skin from premature aging with stellar ingredients like CoQ10 and Alpha Lipoic Acid. There's, no doubt, an antioxidant serum out there that's perfect for your skin type and skin concern — and these nine are more than just hype.
