Abreva is a cold sore treatment that contains 10% docosanol. It works to immediately soothe the discomfort and irritation of a cold sore. Then, it goes deep in the skin to actually change the structure of the cell membranes that surround healthy skin cells. Abreva turns them into barriers against the cold sore virus, making it harder for the virus to spread.
For best results, use ABREVA® the moment you feel a cold sore coming on. Learn what triggers your cold sore and how to recognize the signs of a tingle, redness, bump or itch so you can start to heal it as soon as you feel it.
Apply five times a day until healed for up to 10 days. Apply with a Q-tip or with fingers, but do wash hands before and after applying the cream. Use an ample amount to completely cover the sore and the area around the sore for best results. Per package directions, rub in gently, but completely. ABREVA® dries clear once rubbed in.
