Vitamin C powder benefits for facial skin
Not all forms of vitamin C can pass through your skin. In order for your skin to use vitamin C, it needs to be in a form called ascorbic acid. However, ascorbic acid is unstable and breaks down when exposed to heat, oxygen, or light.
The ascorbic acid in powdered vitamin C is more resistant than other forms, and it's thought to retain more of its benefits than vitamin C found in serums or lotions. Some of the benefits of applying vitamin C to your face include:
Vitamin C acts as an antioxidant
Vitamin C is the most abundant antioxidant in your skin. Your skin cells store vitamin C to prevent damage from environmental factors. UV rays, pollution, and smoking can all damage your skin by creating free radicals. Free radicals are unstable molecules that pull electrons from your cells and cause damage.
Vitamin C promotes collagen production
Collagen makes up the majority of the dry weight of your skin. Your body needs vitamin C to synthesize this protein. Many of the symptoms of vitamin C deficiency (scurvy) are caused by impaired collagen synthesis.
In a 2015 study, a group of 60 healthy women applied a vitamin C-based solution to their face for 60 days. The researchers found that the vitamin C solution was highly effective at inducing collagen synthesis.
Vitamin C lightens skin
Vitamin C inhibits an enzyme called tyrosinase. Tyrosinase converts the amino acid tyrosine into melanin, the pigment that gives your skin its color.
Vitamin C replenishes vitamin E
Vitamin E is another important antioxidant that protects your skin from oxidative damage. After your skin is exposed to sunlight, levels of vitamin E decline. Research has found that vitamin C helps replenish vitamin E after sun exposure.
Vitamin C powder uses for your face
There's a limited amount of research looking at the effect of vitamin C powder on your face. However, based on research using other topical forms of vitamin C, powdered vitamin C might have the following benefits:
Vitamin C powder for treating sun damage
Applying vitamin C to your face may help reduce the appearance of dark spots caused by sun damage. Topical vitamin C inhibits the production of melanin, which is what gives skin spot their dark color.
Vitamin C powder for preventing skin sagging
Your skin naturally produces less collagen as you get older. A loss in collagen is one factor that causes your skin to sag as you age. Applying vitamin C to your face may help improve your skin's production of collagen, especially if you spend a lot of time in the sun or are low on dietary vitamin C.
Vitamin C powder for wrinkles
As you get older, your skin tends to become less elastic and thinner, which can contribute to wrinkles. Although the formation of wrinkles is largely genetically predetermined, repeated exposure to UV rays can break down collagen and elastin and prematurely age your skin. Applying vitamin C powder to your face may protect it from sun damage.
Vitamin C for wound healing
Your body requires vitamin C in all stages of wound healing. Applying vitamin C to a wound may speed up healing and reduce scarring.
Vitamin C for protecting skin from sun and pollution
Your skin is constantly exposed to damaging UV rays and pollution in the atmosphere that can cause oxidative stress. Vitamin C acts as an antioxidant to protect your skin from this stress. Applying vitamin C powder to your face may help saturate the amount of vitamin C your cells have available.
Unproven claims about powdered vitamin C for your face
Some people claim that powdered vitamin C may do the following, but these claims are based only on anecdotal evidence.
Vitamin C for under-eye circles
Some people claim that vitamin C helps them reduce under-eye circles. Vitamin C may help eye circles by stimulating collagen production.
Vitamin C for exfoliating
When you mix vitamin C powder with a moisturizer or lotion, the solution may have a gritty texture. This grit may help exfoliate your face.
How to apply vitamin C powder to your face
When applying a vitamin C powder to your face, it's important to make sure that you're using a powder meant for topical use. Applying crushed-up vitamin C meant to be eaten as a supplement likely won't be effective. Here's how you can apply powdered vitamin C to your face:
- Add a small amount of powder to the palm of your hand. The package will likely give you specific instructions on how much to use.
- Mix the vitamin C powder with a serum or lotion in the palm of your hand. Research has found that for vitamin C to be beneficial, it needs to make up at least 8 percent of the solution. A concentration higher than 20 percent may cause skin irritation.
- Apply the solution either to your entire face or as a spot treatment.
As with any skin care product, it's a good idea to test a small amount of powdered vitamin C on a small section of your skin in a less-visible spot 24 hours before applying it to your whole face. This way you can see if you're allergic to it.
Powdered vitamin C is thought to be more stable than other forms of vitamin C. You can mix it with skin serums and lotions to help improve your skin health. For the best results, you should use less than a 4-to-1 ratio of vitamin C to your lotion or serum.
