There are several causes for hyperpigmentation. If you refer to hyper pigmented acne pimples you need to start with the control of your active acne. Use your MDacne app to assess your skin and to get a suggested personal skin care routine. People who have a tendency to hyperpigmentation MUST use in the morning an oil-free sunscreen and avoid sun exposure. Once, active acne is controlled, the overnight anti-acne cream can be replaced with a whitening cream to fade the brown spots. Check the TIPS section of your personal routine for specific product suggestions.
