I suggest seeing an expert for an evaluation you likely need a combination of peels, skin care and lasers. Best, Dr. Emer.
Hyperpigmentation is common with acne. Bleaching creams can be very helpful in treating hyperpigmentation if used correctly. It will take months to resolve. Strict sun precautions and sun avoidance is required. Evaluation by a qualified professional is necessary in order to determine what the appropriate treatment is for you. Good Luck!
I treat a lot of patients with dark skin and hyperpigmentation. I find that the best combination to treat your condition are chemical peels combined with hydroquinones to treat this discoloration. Please consult an expert. Strict sun avoidance is necessary for the best success. Best, Dr. Green
In my opinion, it's totally normal for you to have pigmentation after inflammation of the skin. Depending upon your skin color, the pigmentation can be mild or very dark. Treatment for this condition is readily available. Go to a doctor and get a bleaching cream. It will usually take a few months, but it should lighten the spots. Should that not be fast enough or complete enough, chemical peeling is helpful. With your tendency, sunscreen should be used on any areas of inflammation. Hope this helps. Good luck.
