I bought Anbesol Maximum Strength Cold Sore Treatment for a recent cold sore I had. To say the very least I was not very impressed. The only benefit that this treatment had was that it temporarily numbed my lip. It left a white, chalky film on my lip that drew even more attention to my cold sore than need be. Also, my healing time was not reduced whatsoever. When I spend money on a product, I expect that it will work. I only tried the Anbesol Maximun Strength Cold Sore Treatment because the cost was significantly lower than other, more popular name brands. I really pretty quickly that there was a reason for the cheaper price. The quality was terrible! In the future I will definitely spend the extra money and buy the vitimin Lisine, which tends to do much better than this product did. I was very dissapointed, as Anbesol is known to make great oral care products. Oh well, lesson learned!
