I realize this is necroposting but I did buy a IPL that looks almost exactly like the one in your image.
It did not help, at all.
First of all, you can't use IPL on darker skin. Also- you can not use them over tattoos. It will scar over your ink.
Those things don't apply to me but its something to know about IPL. How these work is that they target the pigment in the hair's root to "zap". However, it doesnt even do that. You also have to shave before using the IPL. Shaving made my condition worse, so I'd rather not do it. IPL doesn't even work and my hairs can still be seen even if shaved.
IPL is nothing like clinic laser you'd pay for at a salon. Different machine entirely. This thing was a total waste of money.
In an ideal world I would get electrolysis done, but I can not afford it.
I paid for salon laser and it was not helpful for lighter hairs. It only worked on darker hairs, and that became too expensive for me as well.
Anyway, IPL is a scam. Don't waste the money. Even professional lasers only work on dark hairs, so you're fucked over if you have blonde, red, or light hairs.
