Thanks for posting question on HCM,
You are suffering from hpertrichosis of face / hirsutism
there are three ways to deal it.
1. Waxing or plucking
2. Taking anti Androgenic medicines for longer time like spironolactone
3. IPL. Or LASER
Since your skin is getting reaction with plucking you may try other remedies and consult any skin specialist near .
For your pigmentation apply advantan cream bid for 1 week only
Hope this will alleviate your anxiety
