Whether it is laser or photon, its mechanism of action is to beat some "pigments" in the skin with light, such as making melanin and red hemoglobin; Or take water as the target to remove epidermis and improve wrinkles and acne. No matter what the target is, the light will provide energy to the target after entering the skin. Using this heat energy, we can "burn" melanin, hemoglobin, epidermis, etc., which is necessary for treatment. However, this kind of heat will also stimulate the inside of the skin to a certain extent, and then cause skin inflammation.
