Brown spots in the skin are often Freckles or Sun spots. Freckles is due to increased melanin and fade or go away in the winter months. Sun spots may reduce in winter months but do not go away.
Both are a sign of sun damage and Dr Prasad would perform a full Skin survey and dermoscopy on your skin to check the nature of these pigmented areas and the discuss your treatment options with you. These include starting on ZO SKIN HEALTH regime and chemical peels and within 3-6 months these areas will be reduced.
