Though on the product boxing it is recommended to be used daily and a couple of applications per day, however, I do not recommend that. As Vitamin A and Salicylic Acid may be a bit too damaging for the skin to apply too often. Also, you may get the skin too adapted to it that it may cause further problems in the future. This is a great treatment for acne problem skin. Do keep in mind that this shouldn't be applied to sensitive skin, or areas with thin skin; such as the area around the nose. I do not like the fact that the product causes the drying of the skin, however, that is one of the thing that tags along when you use products with Vitamin A and/or Salicyclic Acid, so that shouldn't be too much of a concern. This is "the" thing that I would always carry in my bag, whenever I feel a pimple coming, I rub it on, and it would disappear in no time.
