How It Works: For treatment of facial hair growth in women, doctors sometimes prescribe a cream called eflornithine. The cream is applied 2-3 times a day, until the hair softens and becomes lighter — similar to the pigment-free vellus hair. Some have reported skin irritation and acne as side effects. Talk to your dermatologist if you would like to use prescription treatments removal of hair.
Some doctors prescribe antiandrogen medications for reducing the appearance of undesired hair. Androgen hormones have been proven to be responsible for hair growth in unwanted area. These medications block the production of androgen, and so can reduce hair growth. Doctors often prescribe oral contraceptives together with these medications in order to enhance their effect, avoid pregnancy (since antiandrogens can be harmful to a developing fetus) and to help make the menstrual cycle more regular in girls who need it.
How Long It Lasts: If treatment is continued, it can permanently remove hair and prevent further growth.
