"i started in february.... in march my face was horrible ... i literally began panicking around april l, some huuuge bumps came up.... i went and did alot of research and they said that was normal and its refered to as the &quot;purge&quot; phase. i download led the epiduo app to keep track of my face (it helps) i didnt see improvements till around june.... and its gradually gettin better... i use it every other nite.... and i spot treat after with a beta hydroxy formula. i would recommend u try it if u have bad acne and in need of smooth clear skin. i tried everything before... so much money and products wasted. pricey but worth it."
