MT-II is essentially a polypeptide that mimics natural melanocyte-stimulating hormone (MSH). However, its modified form more effectively activates melanocytes in the skin, promoting the production and distribution of melanin granules, thereby deepening skin tone and forming a natural "sunscreen layer." This mechanism differs from traditional topical sunscreens; it fundamentally enhances the skin's own defense system, allowing skin beautification and care to occur simultaneously.
