Hello, Dark spots or dark patches on the skin are commonly due to exposure in the sun. It can be hyper-pigmentation due to hormonal issue, liver issues, different levels of melanin in the skin, genetic factors, etc. Dark spots or dark patches are harmless conditions but at times they can be cancerous, get clinically examined by a dermatologist. Get skin biopsy and tests done to rule out cancer. Hormone replacement therapy and liver tonics are effective. Take liver tonic (Liv 52) and food good for liver, berries, grapes, sugarcane juice, cruciferous veggies, nuts, fatty fish, etc. Avoid addictions if any, stay away from fried, spicy food. Take adequate sleep. Stay well hydrated. Side effects of certain medications cause skin darkening, be careful what medicines your take. Topically you can apply bleaching creams that lighten the skin like creams that contain retinoids alpha hydroxy acid, glycolic acid, deoxyarbutin, and kojic acid. Always wear sunscreens with SPF when outdoors. You can apply Betnovate C ointment at bed time, never apply it when you are outdoors. Do not apply ointment Betnovate C for more than a week (6-7 days) for it is a steroid. You can apply natural face packs that contains turmeric, milk & lemon juice. Apply it twice daily. You can consult your dermatologist for chemical peels, laser treatment, microdermabrasion, etc. They are effective. Take care. Hope I have answered your question.
