What is it?
Serine is a non-essential amino acid that is a fundamental building block of proteins. It possesses a hydroxyl group in its side chain, making it a polar molecule that is highly reactive and versatile. In skincare, serine is recognized for its role as a natural moisturizing factor, which maintains the skin's hydration and overall vibrance.
Where does it come from?
Serine is naturally synthesized in the human body from other amino acids such as glycine and threonine. It is also found in various dietary sources, including soy products, eggs, meat, fish, and dairy. In skincare products, serine is derived through fermentation processes involving bacterium or extracted from protein hydrolysates.
