Peptides are very small pieces of proteins consisting of various numbers of amino acids



Peptides, also known as polypeptides, are short chains of amino acids that are the building blocks of proteins. Peptides in cosmetics have been found to help improve skin structure, function, and appearance.


Studies show that peptides can act as messengers in the skin, signaling cells to perform various functions, such as producing collagen, elastin, and hyaluronic acid. These are essential components for maintaining skin firmness, elasticity, and hydration. A 2019 review shows peptides can also modulate inflammation, wound healing, and pigmentation.


Peptides have anti-aging effects on the skin, as they can reduce the appearance of fine lines, wrinkles, and sagging. They can also help repair and protect the skin from environmental damage and oxidative stress.


Peptides are classified into different types based on their structure and function. Some of the most common types of peptides used in skin care products are signal peptides, carrier peptides, enzyme inhibitor peptides, and neurotransmitter inhibitor peptides.


Peptides are synthetic or natural molecules easily incorporated into various skincare products. They are generally well-tolerated and safe ingredients that suit most skin types and can be combined with other skincare ingredients. They are potent and effective ingredients that can target multiple skin concerns and improve your skin’s overall health and appearance.
