Firstly I would want you to understand complexion shouldn't be an issue in life to be under confident or sad. However to help you out with your complexion, you may try these
1) use a Glycolic acid
face wash twice in a day ( melawash)
2) take oral vitamin c
supplements and antioxidant supplements
3) use a sunscreen of SPF 50 esp when going out. Apply it twice in a day in between 10 am to 4 pm as sun damage and tanning
is maximum in this duration
4) use melalite forte cream in night. Do not use it for more than two months. Use it in a small amount over face and do not rub the cream too much. If redness
or any burning sensation develops discontinue its use immediately. Once desired results are achieved use a milder cream like melaglow over your face.
5) you may also use depiwhite face mask twice in a week for good results.
Hope that will help you.
