Every ingredient used in cosmetic formulation is added for a specific purpose. There are many different types of cosmetic ingredients, such as emollients, humectants, emulsifiers, preservatives, fragrances, etc. Active ingredients covers a large range of ingredients with specific characteristics and benefits for skin. Peptides belong to this category alongside vitamins, hydroxy acids, antioxidants and extracts.
What are Peptides? Peptides are the middle child in a family of amino acids and proteins. They are molecules smaller than protein and larger than amino acids. They contain something between 2 to 50 amino acids. Proteins are amino acid chains longer than 50, making them more complex and too large to penetrate the skin. That is when peptides come into picture. Peptides are an excellent addition to skincare products. Because of their smaller structure they are easier to penetrate the skin making them essential in many biological processes in the cells in our skin.
Peptides can signal your cells to increase the production of skin structural proteins such as collagen and elastin. They can also play a role in brightening skin’s complexion. They can also attach to other bioactives used in the skincare product and act as a delivery system, making sure they reach the correct target in skin.
If you want to nourish your skin with the magical benefits of peptides look into Elevate, firming facial cream. It contains Hexapeptide I. This peptide is developed from Saccharomyces Cerevisiae (a primitive single celled organism) cultured in an amino acid rich environment. It is then gone through fermentation and Hexapeptide is isolated using various filtration techniques. Hexapeptide I benefits can be summarized as improving skin tone and elasticity and hydration. It also can increase ATP (energy currency of the cell) synthesis which may help with overall cellular efficiency.
