Those who have such doubts are mostly worried that eating soy sauce after mole spotting will cause pigmentation and scarring, but although soy sauce is dark in color, it usually has no effect on skin pigmentation and scar formation because the pigment in soy sauce can be metabolized by the body and will not reach the skin. Generally, if pigmentation and pigmentation appear after laser mole spotting, it is not caused by eating soy sauce, but may be due to not paying attention to sun protection after mole spotting or being a spot-prone body with deeper skin pigmentation. In addition, if no attention is paid to skin care after laser mole spotting and local inflammation occurs, or if the patient is a keloid, a scar may be left behind. In addition, if you choose an informal medical institution with unprofessional operation and improper control of laser energy level, scarring may also occur. It is recommended that after laser mole surgery, patients should pay attention to sun protection, minimize outdoor activities, and use sunscreen, umbrellas, hats, masks, etc. for protection. At the same time, you need to avoid spicy and allergic foods, as well as tobacco and alcohol to avoid infection.
