Why are peptides important?

Hint:Peptides are naturally occurring substances in the skin which are also included into some skin care products to improve the skin and take care of the same.
They are the amino acids that make up certain proteins which are needed by the skin on high requirements.

Complete step-by-step answer:Let us know more about the peptides;
Peptides-
More commonly known as poly-peptides are the smallest versions of proteins found mostly on the skin. The cosmetic products contain different types of peptides which make up the collagen needed by skin.
The collagen which is made up of three peptides linked together is the main ingredient for anti-aging, anti-inflammatory and muscle building properties which lead to firm and young-looking skin.
Thus, peptides are important for betterment of skin; many dermatologists also suggest to eat peptide rich foods and also externally, peptide rich products to be used.

Note:Do note that skin can look wrinkled and less even due to the decrease in the collagen produced by the skin after a certain age limit.
Also, do not get confused proteins and peptides; both are made up of amino acids. The peptides contain the fewer amino acids unlike proteins but both peptides and proteins are present in the natural foods.
