The Benefits of Antioxidants: A Must-Have in Your Skincare Routine

The Benefits of Antioxidants: A Must-Have in Your Skincare Routine

Whether you’re a skincare minimalist or an enthusiast with a 12-step night skincare routine (no judgment here!), you’ve likely found a place for a face serum with vitamin C on your skincare shelf. What you may not know is that vitamin C belongs to a powerful group of skincare ingredients known as antioxidants. If your goal is youthful-looking skin (and really, whose isn’t?), you’ll want to read on to learn all about the benefits of antioxidants in skincare. Spoiler: Glowy skin is definitely on the list!

What are Antioxidants and What do They do for Skin?

Antioxidants are naturally occurring substances that act as a shield against free radicals—unstable atoms that cause damage to cells. Free radical damage is triggered by sources of internal and external stressors (think: UV exposure, lack of sleep, pollution, and poor nutrition just to name a few). Without the help of antioxidants, free radical damage can lead to common skin concerns such as lack of firmness, fine lines and wrinkles, uneven skin texture and skin discoloration.

As we age, the levels of antioxidants our skin naturally produces slowly depletes. However, with the power of topical antioxidants, we can hack this process by protecting the skin. Enter: antioxidants in skincare. “Topical products containing antioxidants have been shown to be effective in replenishing these antioxidants and protecting the skin against the damaging effects of free radicals produced by normal cellular metabolism or UV damage,”1 according to a study published in the Journal of The American Academy of Dermatology.

Common antioxidants in skincare include vitamin C, vitamin E, ferulic acid, retinol, niacinamide and resveratrol. By introducing skincare with antioxidants into your lineup, you’re already on your way to better-looking skin by curbing the effects of sun damage—one of the leading causes of premature skin aging.

Why Antioxidants Belong in Your Night Skincare Routine

Ever wondered why there’s such a major focus on night skincare routines, especially for aging skin? There’s compelling science to back up this skincare norm. Human skin cell regeneration has been shown to be 30 times higher at night than in the day. With this rise in skin cell turnover and DNA repair, the skin also experiences the highest levels of moisture loss and increased permeability.1 Using antioxidants in your skincare at this crucial point of elevated skin absorption can compensate for the changes your skin experiences overnight. Also, with increased skin absorption at night, it’s more likely that your products will actually be absorbed into skin (where they can work their magic!).

Thinking of what skincare products to use tonight? Keep in mind that the best night serums and moisturizers seal in the hydration lost during sleep and contain active ingredients—like antioxidants. Add an antioxidant serum to your night routine and see changes to dull skin, uneven skin tone, hyperpigmentation, fine lines, wrinkles and more.

Meet IT’s Best Antioxidant Serum with Triple the Goodness

For the ultimate antioxidant boost (which will translate to glowy skin), use a face serum with vitamin C plus powerful supporting antioxidants, like Confidence in Your Beauty Sleep Triple Antioxidant Brightening Serum, which combines vitamin C, ferulic acid and polydatin.

Clinical studies have shown that combining topical vitamin C with other ingredients, like ferulic acid, can help repair the effects of sun damage3. Within our formula, ferulic acid acts as a stabilizer that boosts the efficacy of vitamin C. It’s also coupled with polydatin, a resveratrol derivative and natural antioxidant, for a serum with even more skin tone-evening properties.

Dr. Julia Tzu, dermatologist and IT Cosmetics Advisory Board Member, explains how it works: “One way to improve the look of visible signs of skin aging is by helping the skin combat damaging free radicals from environmental stressors. Infused with antioxidants, Confidence in Your Beauty Sleep Serum boosts your skin’s antioxidant protection while reducing the look of fine lines and wrinkles after just 4 weeks.”
