Vitamin C has an excellent safety profile. Most people can use topical vi-ta-min C for an extended period of time without experiencing any adverse reactions.

A 2017 đánh giá of research notes that vitamin C may cause minor skin irritation in concentrations above 20%. Because of this, its concentration often ranges between 10% và 20% in skin care products.

Vitamin C is also safe lớn use with other skin care actives, including alpha hydroxy acids, retinols, & SPF.

2. It’s hydrating

According lớn a 2017 research review, most healthy skin and organs contain high concentrations of vitamin C, suggesting that vitamin C accumulates in the body toàn thân from circulation.

Review authors noted that topical vi-ta-min C penetrates the skin best in the khung of ascorbic acid.

Magnesium ascorbyl phosphate, another vi-ta-min C derivative used in skin care, has been shown lớn have a hydrating effect on the skin, according to lớn a 2022 review. It decreases transepidermal water loss (TEWL), allowing your skin khổng lồ retain moisture better.

According lớn a 2019 study, an antipollution, antioxidant serum containing Deschampsia antarctica extract, ferulic acid, and vitamin C reduced TEWL by 19 percent, improving the skin barrier function.

Vitamin C can help fade pigmentation (more on this below!) & smooth the skin’s surface to reduce dullness. This gives skin a youthful glow.

A 2017 reviews notes that vitamin C use has been shown to impede melanin production. Melanin is the pigment responsible for skin color.

The anti-inflammatory properties of vitamin C can also help reduce redness, which in turn can create a more even complexion.

The combined reduction of dark spots, redness, & irritation makes for a clear, smooth skin tone.

5. It helps fade hyperpigmentation

Since it impedes melanin production, vi-ta-min C can actually fade hyperpigmentation.

Hyperpigmentation — including sunspots, age spots, & melasma — occurs when melanin is overproduced in certain areas of the skin. It can also happen in areas where acne has healed.

Vitamin C inhibits melanin synthesis by downregulating the activity of an enzyme known as tyrosinase. It’s widely used in dermatology for reducing pigmentation of hyperpigmented spots on the skin.

It’s also been used to treat gingival melanin hyperpigmentation (gum hyperpigmentation), though studies are limited.

Dealing with acne? In addition to lớn vitamin C serums, there are other options for treating hyperpigmentation acne.

6. It reduces the appearance of under-eye circles

Vitamin C serums can help smooth out fine lines by plumping và hydrating the under-eye area.

Although vi-ta-min C is more effective at reducing overall redness, some people say it can help alleviate discoloration associated with under-eye circles.

According lớn a small 2019 study on three treatments for dark circles, vi-ta-min C mesotherapy resulted in a significant improvement in the pigmentation of under-eye circles. However, some participants also reported a burning feeling.

Some other ways to lớn help get rid of under-eye bags include using a cold compress & adding retinol to lớn your skin care routine.

The skin under your eyes is thin & sensitive, so it’s best lớn stick khổng lồ products specifically designed for the under-eye area.

7. It promotes collagen production

Collagen is a naturally occurring protein that depletes over time. Lower levels of collagen can lead to fine lines và wrinkles.

Vitamin C is well known for boosting collagen production through the process of collagen synthesis. In fact, collagen synthesis can’t happen without vitamin C.

This is because vi-ta-min C is the essential cofactor for the two enzymes required for collagen synthesis:

prolyl hydroxylase, which stabilizes the collagen moleculelysyl hydroxylase, which provides structural strength

You can also boost collagen production through your diet.

8. It may help prevent skin sagging

Collagen production is tied to lớn skin elasticity & firmness. When your collagen levels begin lớn drop, your skin may also begin to lớn sag.

Applying a vitamin C serum may boost collagen production, resulting in an overall tightening effect, reports a 2017 review. This is true for sagging due to lớn natural aging, oxidative căng thẳng damage, or extreme weight loss.

This means it can help reduce the appearance of sagging skin, making your skin look firmer and more toned.

9. It protects against sun damage

Excessive exposure khổng lồ oxidant căng thẳng via pollutants or ultraviolet (UV) irradiation is associated with depleted vitamin C levels in the skin.

Vitamin C levels are also lower in more mature or photodamaged skin, though researchers are unsure whether this is a cause or effect.

Sun damage is caused by molecules called không tính phí radicals. These are atoms with a missing electron. Không tính phí radicals search for other atoms from which they can “steal” an electron — & this can lead khổng lồ significant damage to lớn the skin.

Vitamin C is rich in antioxidants. Antioxidants protect healthy skin cells by “giving” these không tính phí radicals an electron, rendering them harmless.

10. It may help soothe sunburns

In addition to lớn minimizing redness, vi-ta-min C accelerates cell turnover, according to a 2017 review. This replaces the damaged cells with healthy new ones.

Topical application of vitamin C, in combination with vitamin E và other compounds, has also been shown khổng lồ reduce injury due to UV irradiation (aka sunburn), notes the above 2017 review. This combination also decreases the inflammation induced by excessive UV exposure.

It’s important to chú ý that researchers found that vi-ta-min C alone is only minimally effective at reducing sunburn on its own.

11. It generally helps boost wound healing

Given its effects on sunburn, it should be no surprise that topical vi-ta-min C application can tốc độ up overall wound healing. Healthy wound healing reduces your risk of inflammation, infection, & scarring.

In fact, having a deficiency in this key vi-ta-min can make wounds take longer to heal.

A 2017 đánh giá found that taking vitamin C supplements had a positive effect on skin healing & growth by boosting antioxidant levels in the toàn thân and the skin.

This is partly because wound healing is associated with collagen formation, & vitamin C boosts collagen production.
