I am 15-year-old suffering from dark spots on the face. They are dark brown, and my usual skin tone is golden brown. I developed acne when I first started puberty, and I picked at my face, which caused these scars. I have tried Vitamin C, and Mederma gel to lighten them, but nothing works. I want to know if there is some way to lighten them. Would Calamine lotion work perhaps anything else? How long will it take to heal completely? Am I stuck looking like this forever?
