Currently, there is no medical method that can safely and effectively change skin color permanently. Skin color is mainly determined by genetic factors, and melanin produced by pigment cells (melanocytes) in the skin is the main factor affecting skin color. Although there are some ways to temporarily change skin color, such as whitening skin care products, laser treatments, and chemical peels, these methods can only temporarily affect skin color to a certain extent, and usually require repeated treatments to maintain the effect. It should be noted that many methods of changing skin color may have side effects, including skin allergies, irritation, uneven pigmentation, and long-term use may cause more serious health problems. Therefore, before trying any treatment, it is recommended to consult a professional dermatologist to understand the possible risks and effects. At the same time, accepting and cherishing natural skin color and promoting social recognition of diversity and inclusion is also an important social issue.
