It's like a facial. All the impurities have to come out first till it's cleaned out (the impurities being the pimples). Then great skin. Also skin can get irritated by what is being used on it and needs to get use to the medication.Why does acne medicine break you out worse when you first start it?
I heard that they speed up the life of the pimples so they die quicker. I was always told that treatment will always make acne worse and then it gets better
might be your body's reaction to a foreign substance initially
Because i think they are clearing ur pores so....they bring the dirt to the surface? I am not sure why...i really like Clean and Clear persa gel the best...thats my favorite
because it has chemicals that usually burn and shock the skin, then eventually overtime weaken the skin so that you break out all the time
