tetrahydromethylpyrimidine carboxylic acid (ectoine)

Ectoine is a highly hydrophilic substance with a strong ability to complex with water molecules, helping to keep the moisture of skin cells. It is internationally recognized as one of the most effective moisturizing ingredients. Ectoine can effectively block ultraviolet (UV) rays, providing good results in combating photoaging and repairing UV-induced cell damage. Additionally, ectoine can promote the synthesis of collagen and elastic fibers, thereby improving skin elasticity and firmness, and promoting skin regeneration. It also shows excellent effectiveness in soothing sensitive skin and reducing skin inflammation. Even in extreme environments with high temperatures, high salinity, and strong UV radiation, ectoine maintains good stability and bioactivity, protecting cells from damage. As a natural compound, ectoine is safe for both the environment and the human body.
