Detailed Answer:
Hello,

After going through your medical query I understand your concern and I would like to tell you that dark underarms and elbows are not serious problems. It depends on your gene, race and physical condition.

In your case, we can say you have this darkness due to hormonal imbalance caused by PCOS.

And to reverse this you need to be physically fit and healthy. Eat a proper diet, reduce carbs and sugars in your meals and exercise daily for 1 hour, this will really help you to maintain a healthy weight and balance hormones naturally.

Apart from this, you can

1. Massage with cucumber or potato
2. Apply milk thistle extract
3. Apply lemon, glycerin mixture
4. Consult a dermatologist for chemical peeling

I hope this information will guide you properly.

Regards
Dr. Bhanu Partap
