Thanks for your question. From your question, I'm assuming you mean the excess hair growth that is seen in PCOS and the IPL hair removal procedure. Any other IPL procedure would work in patients with PCOS without any difficulty. In regards to the excess hair growth and the IPL procedure, you should have no problem with using the IPL, and in fact, it is an excellent treatment for the excess hair growth that most people get on the chin, cheeks, jawline, and neck areas. The excess hair growth seen in PCOS is due to the production of excess androgens (male hormones) that then leads to excess growth in male-dependent hair growth areas (e.g. - the beard area). IPL hair removal is used to target the melanin in the hair and the hair bulb, thereby destroying the hair follicle. It doesn't matter what the cause of the hair growth is, where it is, or how much you have. If you have a hair that is dark, IPL will work on it. Hope this helps!
