Isoleucine

Isoleucine is one among the amino acids that possess a branched-chain structure and is an important element in the dietary intake for protein synthesis. It is obtained from dietary sources like almonds, cashews, and soy. Since this amino acid cannot be synthesized de novo inside the body, it needs exogenous supply and thus becomes an important compound for a good number of biological processes, from muscle repair to energy generation.
In skincare, isoleucine acts like a skin-identical ingredient, which truly means it's just like those ingredients that occur naturally within your skin. For this reason, the ingredient becomes highly beneficial and effective in terms of sustaining skin health and hydration. Isoleucine contributes to skin barrier repair by strengthening the skin's natural barrier, which is critical for maintaining good moisture levels and offering protection to the skin against environmental stressors. This ingredient possesses moisturizing properties that effectively enhance skin hydration, thereby leaving the skin feeling soft and supple.
Isopleucine is also supposed to assist collagen synthesis, hence improving skin structure and elasticity. The combination of barrier repair, hydration, and structure supportsmakes isoleucine a key ingredient in the formulation of skincare products targeted at addressing moisture levels and the overall resilience of the skin.
