The beauty industry is buzzing with “super ingredients” that claim to do wonders for your skin, like peptides. Peptides have been cited as one of the critical breakthroughs in skin care.
Why all this fuss? Is it really worth your attention, or is it just another beauty fad? After you finish reading this article, you will understand why the beauty industry is obsessed with peptides. Let’s start.
What are peptides?
Peptides are chains of amino acids and the building blocks of proteins in your body. When amino acids combine into different formations, they create different peptides. And when peptides are formed in a certain way, they create specific proteins.
Proteins are the most basic building blocks of your skin, organs and tissues. And collagen is one of the most important proteins in your body. About 75%-80% of your skin is made up of the collagen protein.
That is why when your collagen production is optimal, your skin looks beautiful. And this is where peptides can help you boost your collagen production. Let’s take a closer look at this.
What do they do and what are the benefits of peptides for your facial skin?
1. Peptides reduce skin aging
2. Peptides Help Reduce Erythema
Erythema or redness of the skin can occur due to various causes, including infection, inflammation, or increased blood flow in your superficial capillaries. A six-month study on 20 subjects showed that both carnosine (a dipeptide molecule) and N-acetylcarnosine (bound to the dipeptide carnosine) can help reduce erythema when applied to the skin. The researchers also found that these two peptides have antioxidant properties.
3. Improve skin firmness and elasticity
In 2 separate studies, the peptide was found to improve skin firmness and firmness and reduce skin sagging.
4. Peptides are anti-inflammatory
According to a study, palmitoyl tetrapeptide-7 has an anti-inflammatory effect on your skin. It suggests that this peptide reduces IL-6 secretion, thus reducing inflammation after UVB exposure. The blend of Palmitoyl Tetrapeptide-7 and Palmitoyl Oligopeptide also improves the structure of the extracellular matrix (the network of extracellular macromolecules including glycoproteins, enzymes and collagen that supports cells).

There are about a hundred peptides. However, only a few are used for skin care.
The best peptides for facial skin
Everyday peptides are mainly classified as:
1. Carrier Peptides
These are Myocept X-50, copper peptides, etc.
Carrier aid peptides love to bring manganese and copper to your skin. These trace elements help and boost collagen development, improve your skin firmness, and help heal it. Copper peptides are commonly used in skincare creams.
2. Neurotransmitter Inhibitor Peptides
These are XEP-30, Palmitoyl Tripeptide-38, Palmitoyl tetrapeptide-28 Argireline, Syn-Ake, etc.
Neurotransmitter inhibitor peptides inhibit muscle contraction, giving your skin a Botox-like effect. If your muscles do not contract, there is no possibility for wrinkles to form. However, this peptide only works on wrinkles formed by expression lines and not the ones caused by pollution, sun exposure, and other factors.
3. Enzyme Inhibitor Peptides
These are Trilagen, Trifluoroacetyl tripeptide-2, silk fibroin peptides, soy peptides, etc.
These peptides inhibit all of the enzymes that break down collagen in your skin. Thus, your skin ages slowly. Most of these peptides generally inhibit the function of matrix metalloproteinases or MMPs. This is a group of enzymes that break down collagen when it develops rapidly.
4. Signal peptides
These are Palmitoyl oligopeptide-7, copper peptides, Palmitoyl pentapeptide-4, Matrixyl-3000, etc.
These peptides usually send signals to the skin to boost the production of elastin, collagen, and any other protein that might keep the skin fresh and young.
Now the question is, how do you get these peptides? Here is a list of foods you can include in your diet to increase peptides in your system.
Natural sources of peptides in products
Milk is one of the most common sources of food peptides. Bioactive peptides found in milk were the first food peptides to be widely studied. Milk is rich in whey protein and casein. After digestion, both of these components can be processed into a range of peptides with antimicrobial and therapeutic properties.. Just be careful, as consuming dairy can cause inflammation. Choose as many organic and herbaceous varieties as possible.
These are rich sources of food peptides. Peptides IRW and IQW have anti-inflammatory properties and also contain antioxidants.
Soy and many other beans contain peptides that have been linked to numerous health benefits. The study states that soy peptides have antioxidant and anti-fatigue properties. He also claims that soy peptide can increase type I collagen in your body..
4. Fish and meat
Fish, especially marine fish, is a rich source of essential peptides and proteins. Peptides in fish may prevent skin photoaging. Fish bones and skin are especially rich in collagen. Marine collagen is mainly used in skin care products and is a very effective free radical scavenger.
Even meats such as pork, beef and chicken are a rich source of bioactive peptides.
Nutrition is a key factor in getting healthy and glowing skin. Oral intake of peptides through food and supplements improves collagen synthesis and skin hydration levels, and restores your skin’s natural barrier.
