Beyond incorporating vitamin-rich foods to your diet, you can boost your levels of Vitamins A, C, D, or E through supplements. Beta-carotene supplements are available without a prescription, but are typically used to treat skin conditions.  Work beta-carotene-rich foods into your diet before turning to supplements.

You may be prescribed a 10 mg (0.00035 oz) melanin tablet to take orally. This is followed by a photochemotherapy treatment involving exposure to UV light. Alternatively, the tablet can be dissolved in a bath and taken topically. The synthetic peptide hormone Melanotan II will speed up the body’s production of melanin. This results in a darker skin tone without any UV exposure. In consultation with your doctor, acquire the product legally with a prescription. You can use a sterile 27 gauge 1 mL (0.034  fl oz) needle to inject a dose (0.025 mg (8.8×10−7 oz) of the hormone per 1 kg (2.2 lb) of body weight) into your abdominal folds. Repeat this process on a weekly basis until you reach your desired skin tone.  Note that Melanotan-II is not FDA approved. It is typically sold online. However, sale and consumption are banned in the U.S., Europe, and Australia.  Dermatologists warn against taking these injections due to the unknown long-term effects.  Melanotan II was designed as an erectile dysfunction treatment. Be aware of the hormone’s ED-related effects.
