Used in skincare formulations for its role in supporting the skin barrier function. It helps maintain moisture retention and improves skin resilience, particularly in dry or sensitive skin. Often found in moisturizers, serums, and repair creams targeting compromised skin barriers. Also studied for its involvement in ceramide synthesis, contributing to the structural integrity of the stratum corneum. Shows potential in anti-aging products due to its ability to reinforce skin’s natural protective layer and reduce transepidermal water loss.
