Thanks for the query. Skin tone is something which one inherits, but skin care is a daily ritual. A good skin care regimen comprises 4 steps - cleansing, toning, moisturizing and sunblock. Based on your skin type, a dermatologist will recommend you appropriate products. There is no magical therapy for dark complexion. However, depending on the presenting complaint, you may benefit with therapies with chemical peels or lasers. No wonder medications will help. The market is full of fake brands and waiting for customers like you. Apply your knowledge and reasoning and decide.
