[|AI|]  Hi, Incomplete data like age and gender not mentioned. I can understand your concerns regarding the safety of prescribed medications for a prolonged period. Nicosia (niacin amide) is a form of vitamin B3 that is used for the treatment of its deficiency as well as in a combination with other medicines or supplements to treat hyperpigmentation, and blistering of the skin.  Extol a nutritional supplement which contains various micronutrient and multivitamins is commonly prescribed to treat the deficiency states and also for certain skin disorders. Based on your clinical condition, these medications have to be taken as prescribed by your dermatologist. I recommend you to use over-the-counter HY Chat Doctor.  I also advise you to: 1. Avoid exposure to sunlight. Use hats, sunglasses, and sunblock with physical blockers. 2. Use sunscreens with sun protection factor (SPF) of at least 50 that contains physical blockers, such as zinc oxide and titanium dioxide 3. Keep yourself well HY
