Vitamin C For Skin: Why It’s Your Daily Essential

Vitamin C For Skin: Why It’s Your Daily Essential

Vitamin C has been key ingredient in skincare for several years now and for good reason. This potent antioxidant protects against environmental damage, strengthens, firms, and brightens the skin. If you’re not already sold on why you need vitamin C in your skincare ritual, let our guide to all things vitamin C for skin help you find the perfect C-packed product for your complexion. 

What is Vitamin C?

Vitamin C is an antioxidant that stimulates collagen production, while simultaneously working as an anti-inflammatory to speed up wound healing. But before you start adding in more citrus to your diet, know that topical application is much preferred to ingestion. When applied topically everyday, you can expect to see results in as little as 8 weeks. That’s not to say you should go out and rub a lemon or orange on your skin, it’s actually an unstable ingredient for skincare so needs to be packaged into the right formulation to reap all the benefits. 

We focus on three derivatives of vitamin C, each providing a different piece of the vitamin C puzzle:

L-Ascorbic Acid

What is l-ascorbic acid? The most common form of vitamin C, l-ascorbic acid helps destroy reactive oxidizing agents and other free radicals which can lead to skin damage. Because of this ability, it provides important protection against damage induced by UV radiation. Vitamin C also improves skin elasticity, decreases wrinkles by stimulating collagen synthesis, reduces erythema, promotes wound healing, and treats unwanted pigmentation. Find this wonder ingredient in C-Shield Anti-Pollution Drops, Daily Power C+, Hydra-Bright AHA Hydrator, and Solar Shade SPF 50.


One of the most effective derivatives available. Several clinical studies show its unsurpassed effectiveness at smoothing, brightening, and protecting the skin. More specifically, Et-VC™ increases skin’s suppleness, reduces pores, and hyperpigmentation and offers protection from photoaging after UVB exposure. Find it in C-Shield Anti-Pollution Drops, Daily Power C+, and Hydra-Bright AHA Hydrator.

Ascorbyl Glucoside

A stable derivative that is converted into l-ascorbic acid by natural enzymes in the skin. Provides the benefits of l-ascorbic acid: brightening, firming and antioxidant repair, without oxidation issues. Find it in C-Shield Anti-Pollution Drops and Daily Power C+.

Why Do I Need Vitamin C For Skin?

We can’t prevent our skin from aging, but we can protect it from environmental damage that accelerates signs of aging. Free radical damage from the sun, pollution, and blue light can contribute to fine lines, wrinkles, dark spots, and a weakening of our moisture barrier. 

The biggest benefit of using vitamin C is protection against these free radicals. Free radicals are unstable molecules that “steal” electrons from the nearby atoms in healthy cells, setting off a cycle of free radical creation, which ultimately results in the destruction of healthy cells and tissue. Free radicals are thought to cause a number of skin conditions related to aging, including skin darkening, inflammation, and the breakdown of collagen and elastin—elements that make the skin plump and youthful. Years of exposure to free radicals causes our skin to show signs of aging.

How Do I Choose a Vitamin C Serum?

In order for vitamin C to be effectively absorbed into the skin, it's important that the pH balance is between 2.0 – 3.8. Next, look at the formula and packaging. You’ll notice that vitamin C serums are often in darker bottles or amber glass. This is because it slows the rate of oxidation and preserves efficacy. For our C-Shield Anti-Pollution Drops and Daily Power C+ serums, our unique trio of vitamin C prevents oxidation, regardless of packaging. 

Finally, look at your skin type. Both of our antioxidant serum formulas contain the effective trio but each contains its own unique added benefits. The biggest difference is whether you’re looking to prevent aging or repair signs of aging.

The ultimate skin-protecting power couple, step forward skin-shielders vitamin C and SPF.
