Peptide Facial Treatment

LAST UPDATED: JAN 17, 2023 / By Nura / IngredientsLibrary

Every day there is a new skincare product that claims to improve your skin. Peptides, also known as polypeptides, are normally found in the skin, but they are also present in many skin care products for an excellent purpose.

Peptides are a string of amino acids that are held together by bonds of nitrogen and carbon, which in turn form the specific proteins needed by the skin. Because collagen is composed of three polypeptide chains, introducing peptides may boost your skin’s production of collagen. Increased collagen can lead to firmer and younger-looking skin.

Your body produces collagen on its own. However, collagen synthesis declines with aging, causing the skin to form lines and wrinkles. This lead to dull complexion.

What Are Peptides?

Peptides are amino acid-based protein fragments. Because those amino acids may do various things, when they are joined together, they generate diverse peptides that serve different purpose. What makes Peptide different compared to Protein is, Peptide consist of 2 to 50 amino acids, and Proteins are made up of 50 or more amino acids. Peptides are present naturally in the skin along with many foods and are referred to as “building blocks” because they work together to accomplish specific activities for the skin.

Consider peptides to be a little pile of bricks that form large and complex Proteins molecules in your skin that execute specific tasks depending on how they are configured. They can become an antibiotic to deprive bacteria that can cause illness to us. Peptide can penetrate the skin’s protective barriers and this made it a good ingredient for skincare products.

Different Types of Peptides for Skin

In skincare product, various peptides perform different function in treating the skin. Here we list down some peptide guidance, for your reference when buying peptide facial skincare products.

Matrixyl 3000

Composed of 2 different types of peptides (matrikines palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7). It has aging intervention properties that can be use to treat fine lines and wrinkles. Consistent usage for two months can help reduce deep wrinkles and improve skin tone.

Signal Peptides

Signaling peptides function by delivering signal cascades to fibroblast cells, to boost collagen production. When you apply this peptide topically on the skin, your skin will sense the peptide as a collagen breakdown product. This will trick the skin to produce more collagen since collagen is a protein, and peptide is one building block for protein structure. This boosting collagen production then can help reduce wrinkles and fine lines and giving youthful appearance to the skin.

Copper Peptides

Copper peptides is a form of carrier Peptides are known to serve as antioxidants, protecting the skin from inflammation. Copper peptides also can stimulate collagen and elastin production giving skin the youthful looks. Since copper have anti-inflammatory properties, it can help in treating pigmentation, redness and scarring, and also good for acne-prone skin user.

Benefits Of Peptides  

+ Improves Skin Barrier Function

Certain peptide such as Adhesion Peptide can enhance keratinocyte function. This led to improve skin barrier function since keratinocytes is the main building block for skin barrier.

+ Increases Elasticity

Peptides can help the skin to “bounce back” by increasing collagen stimulation. Better skin barrier will provide good “thickness” to the skin hence improving its elasticity, restoring its youth aspect.

+ Peptides for Acne

Some peptides [CEN1HC-Br]  have antimicrobial and anti-inflammatory properties, and they can deprive P. acnes bacteria that cause acne. 


Peptides are incredibly mutable due to its nature that comprise of up to 50 amino acids. When you add or replace one of those amino acids, you will get a new peptide that may have different function, and that includes firming, anti-inflammatory properties and soothes the skin.
