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.

1. A Stabilized Vitamin C Booster That Targets Uneven Skin Tone

Absorbic acid (Vitamin C) is a powerful antioxidant that protects skin from free radicals and helps even out skin tone that your complexion appears more radiant. The Hylamide Booster contains a patented form of solubilized active resorcinol that is meant to be applied twice daily after cleansing and before applying moisturizer. Reviewers say it makes skin glow and can even help clear up acne.

2. A 2-In-1 Oil-Free Serum With Vitamin E & SPF 50

If you're the type who loves to kill two birds with one stone, this powerful antioxidant serum with Vitamin E, Vitamin Cg, and Baicalin protects against free radicals while broad spectrum SPF 50 works to provide all of the sunscreen protection you need. The cherry on top: it's an oil-free formula that contains no parabens or fragrances and is non-comedogenic — oily, acne prone, and sensitive skin types needn't fear it will clog pores or cause irritation.

3. A Serum With Stabilized Vitamin C That Can Lighten Acne Scars & Sunspots

4. A Hydrating & Protecting Serum For Sensitive Skin

In this French pharmacy serum, vitamins C and E help fight free radicals and reverse the effects of photo-damaged skin, while hyaluronic acid plumps, hydrates, and promotes an overall more radiant complexion.

5. A Dry Skin Savior With Retinol And Antioxidants

If flaky, dry skin is the norm for you, there's a chance you live in mortal fear of retinol making contact with your sensitive skin.

Reviewers call this the "best" serum for dry skin and say it leaves your complexion looking "luminous."

6. An All-Natural, Splurge-Worthy Serum With A Cult-Following

Kypris' Natural Antioxidant Dew Facial Serum has a devoted fan base because of its all-natural, plant-based ingredients and seriously effective formula. Loaded with antioxidant-rich vitamins C, E, and ferulic acid, which help keep skin protected from environmental damage, it also contains sea algae extracts to promote softer, suppler skin. Then, temanu oil works to encourage cell turnover, which helps reduce blemish scars, while other botanicals soothe redness and hydrate. The immediate results? A dewy, healthy glow. Basically, this serum does it all.

7. This Concentrated Powder Booster Allows You To Customize Your Favorite Skin Care Products
