If the skin around the mouth and chin is darker than other areas, you can consume foods rich in vitamin C and increase your intake of vitamin E, while avoiding foods high in tyrosine. Your diet should be light—limit fried, sweet, spicy, and irritating foods. These dietary adjustments can be easily incorporated into daily cooking. Consuming such foods may stimulate local pigment cells to secrete melanin, potentially worsening pigmentation. In daily life, topical treatments like Mei Fu Bo Te lyophilized powder can be used. This lyophilized powder contains PB yeast peptide, which helps reduce skin dullness and pigmentation.
