L-Alanyl-L-Tyrosine is a dipeptide composed of alanine and L-tyrosine, and it has the following main mechanisms of action in skin care products:
·Promoting skin metabolism: L-Alanyl-L-Tyrosine can participate in the metabolic process of skin cells. It can provide nutrients for skin cells, promoting cell renewal and repair. For example, it can accelerate the exfoliation of keratinocytes, making the skin smoother and more delicate. At the same time, it stimulates the generation of new cells, enhancing the vitality and elasticity of the skin.
·Strengthening the skin barrier function: L-Alanyl-L-Tyrosine helps maintain the integrity of the skin barrier. It can promote the synthesis of collagen and elastic fibers in the skin. These proteins are important components of the skin structure, which can make the skin firmer and more elastic, reduce water loss, and resist the invasion of harmful substances from the outside. Thus, it enhances the skin barrier function and improves the skin's tolerance.
·Antioxidant effect: L-Alanyl-L-Tyrosine has a certain antioxidant capacity. It can scavenge free radicals in the skin, reducing the damage of free radicals to skin cells and preventing skin problems such as aging and dullness caused by oxidative stress reactions. For instance, it can inhibit lipid peroxidation, protect the stability of the skin cell membrane, and keep the skin in a healthy state.
·Whitening and freckle-removing: L-tyrosine is a precursor substance for melanin synthesis, and l-alanyl-l-tyrosine may regulate the activity of tyrosinase in the skin. An appropriate addition can competitively inhibit the binding of tyrosinase to tyrosine, reducing the synthesis of melanin. Therefore, it can achieve the effect of whitening and freckle-removing, making the skin brighter and more even.
