Hello and welcome to HCM,
I read you query and understood your concern.
Its very unlikely that surfaz would have caused the
excessive hair growth on your face.
If the hair growth is sudden you should get a condition called
hirsutism ruled out. Get a hormonal work up dont for
polycystic ovarian disease since it is most common cause of hirsutism.
If you have other associated symptoms like acne, weight gain,
irregular menstruation, it all points towards PCOD, and if not the chances are low and it could be without any underlying cause.
The only permanent method to get rid of facial hair is lasers, and electrolysis, done by a
dermatologist. I'd recommend you to go for lasers as it is safer and lesser painful.
You can also talk to your dermatologist about vaniqa cream a chemical method to aloe hair growth but it is only effective until it is being used.
For immediate measure, you can bleach the hair to reduce the appearance.
Hope I helped
