It reduces redness and even out the skin tone
Vitamin C acts as an anti-inflammatory agent through its antioxidant capacity, as the results of a 2015 review are showing. This basically means that its action soothes the skin and reduces puffiness. The inflammatory action of this vitamin is good for:
- neutralizing free radicals that might cause oxidative damage
- optimizes the immune system, discouraging any given inflammatory immune response
The anti-inflammatory properties of this vitamin are also efficient when it comes to fighting redness, which can result in a more even complexion. The combined reduction of dark spots, redness and even irritation are the elements that make a clear and smooth skin tone.
It fades hyperpigmentation
Vitamin C impedes melanin production, so it can really fade the process of hyperpigmentation. Hyperpigmentation, such as sunspots, age spots, and melasma, happens when there’s an overproduction of melanin in some areas of your skin.
It might also happen in areas where acne has completely healed. Vitamin C is a great melanin synthesis inhibitor because it downregulates the activity of an enzyme which is known as tyrosinase.
It is widely used by dermatologists because it reduces the pigmentation of hyperpigmented spots on the skin. Even if the studies are currently limited, it has also been used to treat gingival melanin hyperpigmentation.
