There are other methods you can use to reduce body hairs like the conventional shaving, waxing, plucking, and electrolysis. Since you are so keen on medicine, there are medicines that slow the production of androgen which is the hormone responsible for excess hair.
Birth control pills can reduce androgen production. There are also anti-androgen medication like Aldactone, Proscar that block the production of androgen but may take months to work and have side effects like birth defects. So it is best to stay away if you are planning to have a child .
Vaniqa(eflornithine) also slows hair growth but it doesn't get rid of existing hair. I hope this helps you.
