I have black spots appearing on my face and neck area with increasing frequency , these are not small ones, they are quite noticeable. I had oily skin when i was teenager and suffered from acne which completely stopped once I became 18 years old. I never used to wear sunscreen until I became 25 years old even though we ere staying in desert area. My mother also had these all over her face which she got removed through laser . Is there a home remedy way other than laser?
