We'd rather tell you this now than have you find out after you've bought it. IPL works by targeting pigment, which means it's built for darker, suitable hair on a range of skin tones — not every hair-and-skin combination will respond the same way, and very light, gray, or red hair generally won't respond well to IPL at all, on any device.
It's also not a treatment for PCOS itself, and it won't stop the hormonal signal that produces new hair. What it can do is give you a private, repeatable way to manage the hair that signal produces, so maintenance becomes a small, occasional task instead of a daily one. If that's a fit for your hair and skin, this next part is for you.
