Your reference to PFB makes me think your hair problem is mainly on your face. Your only real option here is electrolysis. It seems daunting for those on a budget, but there’s nothing else to be done. The initial clearance may seem like a lot of money, but subsequent clearances will cost much less, and keep you pretty much hair free in between, without any awkward shedding period. It will also not damage your skin when performed correctly.
A lot of people here pick just one facial area (cheeks, or chin, or upper lip or eyebrows) and focus on that one area that bothers them the most. This will give you results you are happy with, without breaking the bank. Though I’ve noticed those people end up doing it all eventually anyway (they get addicted, hehe).
