Home Beauty Ever wonder why surfer girls have such clear skin? It is because of the all the salt in the sea! A salt mask is one of the easiest homemade pimple-zapping masks that you can make. To make it you need sea salt or cooking salt and some water. You put the salt in the water for 20 minutes then apply the mask to acne spots and leave it on for 10-30 minutes. Salt cleans the skin and dries the pimples out. If you live near the sea, then just go for a swim.
