What Does Vitamin C Do For Your Skin

What exactly does vitamin C do for your skin? Well, it has the potential to help with a lot of issues, especially when applied topically in serum form. Vitamin C has a wide range of protective and anti-aging effects for the skin, Annie Chiu, MD, a board-certified cosmetic and general dermatologist on faculty at Cedars-Sinai Medical Center, tells SELF. Serums typically offer the highest concentrations of active vitamin C and tend to have better skin penetration compared to other vitamin C products, like creams and cleansers. Here are a few of the biggies when it comes to benefits:

Thats because the antioxidant can help your skin produce collagena protein that gives your complexion a firmer, bouncier feel, which in turn helps to improve the look of fine lines and wrinkles, Dr. Chiu explains.

With consistent use, your skin can become more even in toneand downright glowy! because vitamin C inhibits the over-production of melanin, the substance in your body that produces pigmentation in your hair, eyes, and skin.

Vitamin C Serum Boosts Collagen

When people first hear about vitamin Cs uses, theyre often skeptical. It seems like such a simple solution to so many skin problems. But it really does work, and part of its secret lies in its effects on collagen production.

Vitamin C is a key ingredient in the production of collagen. If you arent familiar, collagen is the most common protein in the body. Its found all over, in bones, muscle, skin, and tendons.

In a sense, collagen holds your body together. This is especially true for the skin, where a lack of collagen can lead to sagging and unhealthy skin.

As we age, we produce less collagen. Production can also be affected by smoking or exposure to UV light. And unfortunately, collagen molecules are too big to be absorbed directly into the skin.

But as we mentioned, vitamin C is a key ingredient in collagen, and more vitamin C boosts collagen production. Vitamin C can be used on sensitive areas of your skin that need a boost in collagen.

So what does that actually do for your skin?

Should You Keep Using Vitamin C If It Changes Colors

In topical skin-care products, vitamin C is sensitive to light and air. When exposed to these factors, it becomes oxidized to dehydroascorbic acid, which is less stable and less efficacious, Dr. Hogan explains. Your vitamin C serum should be colorless or a light straw color if it oxidizes, it becomes yellow or brown and is likely going to be less effective. You can still use it if you want, but it probably wont do as much for your skin and, very rarely, oxidized vitamin C products can even cause slight yellow discoloration of the skin, particularly if you have fair skin, Dr. Hogan adds. So consider getting rid of any vitamin C products that have dramatically changed in color or smell since you bought them. Especially if it is brown, I would say to toss it, Dr. Lamb says.

If you cant find an expiration date and youre unsure of how long its been in the back of your cabinet, its probably best to get rid of it. Dr. Lamb says you shouldnt use active ingredients a year after they have been opened because theyre just no longer effective at that point. Will it harm your skin to use it? Probably not. But you may notice that a trusty vitamin C serum can be pricey, so taking care of your bottle will also help take care of your wallet.

Uv Radiation And Photoaging

Skin and The Effects of Vitamin C: Dr. Belo Shares Its Benefits

There is mounting evidence to suggest that the most significant environmental challenge to the skin is chronic exposure to ultraviolet radiation from the sun or from tanning beds . UV radiation damages skin through the production of reactive oxygen species, which can damage the extracellular matrix components and affect both the structure and function of cells. While the skin contains endogenous antioxidant defences, vitamins E and C and antioxidant enzymes to quench these oxidants and repair the resultant damage, these antioxidants will be consumed by repeated exposure and the skins defences can thereby be overwhelmed .

Acute exposure of skin to UV radiation can cause sunburn, resulting in a large inflammatory response causing characteristic redness, swelling and heat. In addition, altered pigmentation, immune suppression and damage to the dermal extracellular matrix can occur . By comparison, chronic long-term exposure to UV radiation causes premature aging of the skin, with dramatic and significant disruption to skin structure, and leads to the development of skin cancer . Termed photoaging, the most obvious features are wrinkles, hyperpigmentation and marked changes in skin elasticity that cause skin sagging, with the skin also becoming sallow and rougher with age . Photoaged skin is most likely to be found on the face, chest and upper surface of the arms.
