Detailed explanation-1: -Collagen[1] is a group of proteins found mainly in the connective tissue of your skin. Your fibrous and supportive tissue also contains collagen protein. Almost 30% of your body protein is collagen. Elastin[2] is a protein created by fibroblasts which form a chain of elastic fibre.
Detailed explanation-2: -Collagen and Elastin Collagen is a fibrous protein that makes up one third of the protein in the human body and is found in the extracellular matrix (ECM). There are 16 different types of collagen, which all have different structures and functions, but only three of them (types I, II, and III) form regular fibers.
Detailed explanation-3: -The dermis makes up 90% of skin’s thickness. This middle layer of skin: Has collagen and elastin: Collagen is a protein that makes skin cells strong and resilient. Another protein found in the dermis, elastin, keeps skin flexible.
Detailed explanation-4: -Fibroblasts. Fibroblasts are usually the most numerous cells in both forms of connective tissue. They are responsible for the synthesis of collagen and extracellular matrix.
