Topical Vitamin C for Fever Blisters

Many people know that vitamin C is essential for good health and can help increase immune function, but did you know that vitamin C could also be effective in the treatment of blisters caused by Herpes simplex and Herpes zoster, also known as shingles? Oral vitamin C can help prevent outbreaks by strengthening the immune system, and it can help shorten the duration of current outbreaks.

Studies show that it is best to start oral vitamin C when patients feel an outbreak coming. Vitamin C supports wound healing by increasing the rate of collagen formation in the skin while preventing further cellular damage from oxidants. Vitamin C also helps in the formation of new capillaries that bring blood and nutrients to the newly forming tissue. Scientific literature shows a wide range of dosing for oral vitamin C. Several studies have used 500 mg two times daily for wound healing with positive results. Vitamin C is a water soluble vitamin, so high doses are safe in those with proper kidney function.

Along with oral Vitamin C, which can benefit the entire body, topical vitamin C can provide direct, concentrated therapy. Vitamin C acts topically to reduce inflammation, prevent further damage from free radicals at the wound site and increase collagen production, which is essential for proper wound healing. Vitamin C is used in many topical cosmetic and skin care products for its antioxidant properties, but a simple paste made from water and powdered vitamin C is just as effective. Research has shown that topical vitamin C can speed up wound healing and decrease the incidence of scarring.

Some research participants also claim that when they feel a cold sore starting (itching or tingling of the skin) that applying topical vitamin C can prevent the sore from appearing. A benefit of using vitamin C topically is the ability to apply large amounts directly to wound. This bypasses the stomach and any irritation that may go along with large oral doses of vitamin C.
