Dr. Hanif warmly Welcomes you! Thanks for consulting at my virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns.   It is not so much due to genetics. It is rather a normal phenomenon and there is no way to make this color white. It is due to hormones. One thing which you may do is don t use razers, creams or chemicals to shave these areas. Rather waxing it is a preferred method to remove hair. It will lead to fair skin with passage of time. If you are overweight, the skin color around neck, armpit, between legs become dark and thick. Try to maintain a healthy weight and it will lead to fairer skin. You may take Perfectil Capsules for skin hair and nails. It will make shiny glowing skin. Hope I answered all of your health concerns . If you have further questions in future, feel free to contact me anytime. In the start of your question write my name, and I will get back to you in no time. If satisfied, please click you found it helpful. Have a wonderful time ahead.   Best Regards! DR. MUHAMMAD M.
