What Does Collagen Do for the Skin?

By SkinCabin

Collagen is the most abundant protein found in our body. It makes up about 75% of our skin. Collagen is present in the extracellular matrix (in-between and around cells).

Collagen is the glue that holds our cells together. It keeps our skin firm. It gives our skin its strength. If the amount of collagen reduces, cells will collapse as collagen is the glue that holds them together.

A single molecule of collagen consists of 3 chains of amino acids. Each chain has approximately 1000 amino acids. These three chains intertwine together to form a single molecule of collagen. Amino acids are the building blocks of collagen.

2 to 3 amino acids together are called a peptide. Hence you can say, an amino acid chain is made up of many peptides. Many peptides (many amino acids) come together to form a molecule of collagen. Peptides are the building blocks of collagen.

With age, the amount of collagen in our body reduces. After the age of 20, the amount of collagen reduces by 1% each year. Reduction in collagen leads to sagging skin, fine lines and wrinkles. Apart from age, another important factor responsible for the reduction/damage of collagen is the UV rays. To prevent the damage to collagen from UV rays, sunscreen wear is a must.
