The most suitable food: tomatoes, oranges and kiwis rich in vitamin C, animal liver, egg yolk and milk rich in vitamin A, and skin, pig's trotters, beef tendon and cartilage rich in collagen.

Reason: After cosmetic surgery, in order to prevent local skin color from deepening and promote wound healing, we can supplement some nutrients that can promote wound healing and whiten skin, such as vitamin C, vitamin A and collagen. Wound healing needs enough collagen, and the formation of collagen fibers needs the help of vitamin C and vitamin A. At the same time, vitamin C can reduce the formation of melanin, and vitamin A can whiten the skin by inhibiting the activity of tyrosinase.
