Topical palmitoyl pentapeptide provides improvement in photoaged human facial skin
Serine is a non-essential amino acid that our bodies can produce on their own. It is involved in various biological processes and is essential for overall health, including skin health. Serine plays a crucial role in maintaining the skin’s moisture balance. It is a component of natural moisturizing factors (NMFs), such as pyrrolidone carboxylic acid and urea. These NMFs help to attract and retain water in the skin, promoting hydration and a healthy complexion. Serine is involved in the synthesis of ceramides, which are essential components of the skin’s barrier function. Ceramides help to maintain the integrity of the skin barrier, preventing moisture loss and protecting against environmental stressors. By supporting the skin’s natural defense mechanisms, serine contributes to healthy and resilient skin. Serine is also involved in the process of wound healing. [17]
