The vast majority of collagen is discovered and produced within the dermis (the pores and skin’s second layer). Right here, fibroblasts synthesize strands of collagen which appear like lengthy braids or ropes. In line with SELF: “Particular person amino acids hyperlink as much as type lengthy chains, which bundle collectively to type thicker strands. These strands then twist and coil round one another to type triple helices. Lastly, these helices join finish to finish and stack on high of one another to type clusters referred to as fibrils.” These fibrils type a collagen community that offers the pores and skin its underlying construction and help.

3 Kinds of Collagen

There are 28 sorts of collagen discovered within the physique, however Kind I, II and III are probably the most plentiful. These three varieties represent as much as 90 % of the physique’s complete collagen provide. Right here’s a breakdown of how they differ:

Collagen Kind I

Kind I is the commonest kind of collagen and gives structural help for our bones, organs and connective tissues (together with the pores and skin). It’s extremely elastic and might stretch significantly with out breaking. In actual fact, an MIT study discovered that Kind I collagen fibrils are 5 to 10 instances stronger than metal.

It might take as much as six months for collagen to get synthesized in our physique. As we grow old, corticosteroids are inclined to halt the manufacturing of recent collagen and speed up the breakdown of recent collagen.” Publicity to environmental stressors accelerates this course of even additional. Unhealthy way of life habits (like smoking and high sugar intake) in addition to stress, air pollution and blue gentle UV rays trigger free radical injury that hastens collagen depletion. By the point we hit our twenties, we lose roughly one % of collagen yearly.

By making use of peptides by way of skincare merchandise, we will really trick the pores and skin into making extra of this important protein. 


Retinol is one other topical ingredient that stimulates collagen synthesis within the pores and skin. In line with SHAPE, “Each retinoic acid and retinol ‘activate’ genes and cells concerned in collagen manufacturing. Additionally they assist arrange new and present collagen.” 

Vitamin C

Antioxidants like Vitamin C pull double obligation and stimulate collagen manufacturing in addition to defend it from depleting sooner or later.
