is vitamin c good for rosacea
Vitamin C, in the form of L-ascorbic acid, has anti-inflammatory effects that act specifically on the blood vessels which can reduce redness and irritation of the skin. Vitamin C can also control the release of histamine, a chemical that dilates the blood vessels during an allergic reaction. Because it can reduce redness and prevent excess blood flow to the skin, vitamin C may be beneficial in controlling the swelling and redness associated with rosacea.
