Roast duck is a high-fat and high-calorie food. If you really want to eat roast duck, I suggest you choose a greasy, low-salt and low-calorie menu and eat it in moderation. It can also be matched with some foods rich in vitamins C and E, such as lemon, raspberry and almond, which helps to promote skin healing.
If your skin condition is serious, please consult a professional doctor or beautician in time. They can give more professional and scientific dietary advice according to their personal situation to help you recover your skin health faster.
