Two suggestions for you: 1. No overeating: Eating too much will damage the spleen and stomach and lead to insufficient qi and blood biochemistry; eating too little will lead to malnutrition and insufficient qi and blood. This leads to deficiency of righteous energy and overflow of evil energy.

2. Do not eat randomly: If the birthmark is accompanied by itching, pain, stiffness, redness, hyperplasia or contracture and deformation, you should be particularly careful about your diet. All fried and moxibustion products, fatty, sweet and greasy foods, and spicy and dry foods should be avoided. Because these foods can stagnate the spleen and stomach and cause dysfunction of health and function. It also increases blood flow, which creates conditions for the deterioration of birthmarks.
