L-serine skin care has been produced since the 1980s, when cosmetic chemists started to understand the importance of serine to the skin. Derived from natural silk proteins, serine produces an important role in the body by helping to form the phospholipids (a major component of the cell membrane) that make up each cell. It also aids in DNA production, fat and fatty acid metabolism, muscle formation, and the maintenance of a healthy immune system (Wikipedia)
Serine in Skin Care and Other Beauty Products
Serine is used in the cosmetic and personal care industry as a skin conditioning agent, anti-static agent, and hair conditioning agent because of its ability to replenish cysteine levels in the hair to keep it strong and smooth. Serine and other amino acids are generally thought to be beneficial to the skin because of their ability to aid in collagen production, boost skin’s elasticity, and replenish moisture (Truth in Aging).
Serine is Broken Down by the Skin in Times of Infection and Stress
Just like collagen is often broken down by enzymes called matrix metalloproteinases under conditions of stress, serine is often broken down by serine proteases under stress as well. When the cells of the body are infected, they tend to respond to stress by releasing enzymes that breakdown serine, called serine proteases (Microbiology Society).
Since serine one of the building blocks of collagen, it is important to keep serine intact.
Serine is an important part of collagen and in maintaining healthy tissues and a healthy body. It’s important to use serine skin care!
