You need to treat both your pigmentation and acne
separately. I would advise you to first get rid of your active pimples
. Once the pimples have subsided, you can take treatment specially meant to reduce pigmentation over your face. For pimples, use a good anti acne face wash and consult a dermatologist
for prescribing you with anti acne medicines for oral and local use. If you have a sensitive skin, the doctor will obviously advise mild preparations so that it does not irritate and darken your skin. you can also use a good sunscreen and take oral supplements of vitamin c
to prevent further darkening of your skin. Once the acne has subsided, your doctor might advise creams meant to improve pigmention and complexion. you can also think of taking microdermabrasion
sessions or peels. The advantages of peels are that they not only tackle pigmentation issues but also helps in acne.As far as melaglow is concerned, there is nothing wrong in using it. It will not help in acne but might help in pigmentation. Take care.
