"I have PCOS so I've been unfortunate enough to have the ugly facial hair situation. Mostly on my chin, and its really coarse hair. My doctor put me on Vaniqa, and I have to say, after all these years of struggling with facial hair removers, waxes, creams, this is the best by far. I've only been on it probably around 2-3 weeks and I saw an immediate difference. Even without using a facial hair remover, its cleared up my skin, the hair doesn't come back as quickly and its really made a huge difference. Granted it is expensive. Hope this helps!"
