Hi.....Post acne pigmentation is very common. Use sunscreens regularly.This ll help in avoiding further pigmentation. Chemical peeling helps in clearing the exciting pigmentation. Other treatment options include lasers, mesotherapies ect.Dark patches at the edges of lips is due to nutritional deficiencies.Take good balanced diet rich in antioxidants like fresh fruit, vegetables, green leafy vegetables, boiled egg ect.consult a dermatologist for appropriate treatment. Hope this ll help you. Have a good day. Regards Dr.Rajitha; HEALING HANDS CLINIC
