Collagen is an important protein that accounts for 70% of skin structure and 25-35% of total protein in the body.

Collagen has a long fiber form, mainly distributed in the dermis layer and acts as a binder that connects the tissue cells into a complete structure, keeping the body firm and stable.

In beauty, collagen plays an important role in creating a smooth, elastic look for the skin. The collagen content in your body will gradually wear out with age and collagen production will also decrease.

When collagen is in short supply, you may experience symptoms like joint pain, stiffness in tendons or ligaments, muscle weakness, wrinkled and sagging skin.
