Hope you are doing great.
PCOS is one of the most common conditions which affects females of child bearing age group. It leads to a hormonal
imbalance whereby the effect of male hormones becomes greater leading to oily skin, pimples on face, neck, back and shoulders, facial hair, hair loss, etc.
You must consult a dermatologist
to cure you. You may email/contact me to help you. Your condition is completely curable with oral contraceptive pills
and anti-androgen medicines. For your facial hair, you can go for laser
hair reduction. But first meet the doctor and take proper medicines. Metformin
won't help you.
Bye and take care.
