Mechanism of Action
As an essential amino acid, Threonine serves as a vital building block for structural proteins such as collagen and elastin, which are indispensable for maintaining skin firmness, elasticity, and overall architectural integrity. It plays a crucial role in fortifying the skin's natural barrier, thereby enhancing its capacity for optimal moisture retention and mitigating transepidermal water loss. Threonine also actively supports the regeneration and renewal of skin cells, aiding in the formation of new, healthy tissue and accelerating the natural wound healing process. Furthermore, it can establish a protective film on the skin's surface and exhibits antioxidant capabilities, safeguarding skin cells from oxidative stress induced by free radicals.
