When thinking about anti-aging skin, many people immediately think of skin care products containing collagen. But in fact, many effective anti-aging products also contain peptides. So what are peptides and what are the effects of peptides on the skin?
1. What are peptides?
Peptide is essentially a long chain of amino acids produced by the body with the effect of biosynthesis of proteins. Therefore, for the skin, proteins are the basic building blocks of collagen and structure of the skin. Peptides are formed through 2 ways: produced by the body itself or supplemented from the outside through different products and foods. The use of Peptides is to strengthen the skin's protection from the sun, prevent skin aging, reduce dark pigmentation and heal damage on the skin.
There are now many types of Peptides, each playing a different role in the beauty industry. For the skin, protein is an extremely important component and one of the most important proteins is collagen. About 75-80% of the skin on the human body is made up of collagen. In addition, collagen also works to maintain youth and youthfulness for the skin. Meanwhile, peptides are an important component to make collagen.
2. Peptide classification
Peptides consist of 2 or more amino acids, linked together by “peptide bonds”. The type of bond that forms when a carboxyl group of one amino acid binds to the amino group of an adjacent amino acid molecule, the reaction releasing a molecule of water. Each Peptide will consist of 10 to 30 amino acids. Then, one or more peptides will bind to biosynthesize a protein.
Currently, Peptides have 4 different forms and the effect of peptides on the skin in each type is also different.
Inhibitor peptide (Neurotransmitter Inhibitor Peptide): This type of peptide is found in injectable products like Botox and topicals. The use of this Peptide is to reduce muscle contractions, help skin stretch and hydrate, and reduce wrinkles by up to 30%. Usually, inhibitor peptides are usually extracted as Argireline (acetyl hexapeptide-8 or acetyl hexapeptide-3, Lipotec); Signal Peptide (Signal Receiver Peptide): This peptide is commonly found in skin care products and has a stimulating or inhibitory effect on cell activity. The use of this peptide is to stimulate the production of collagen, elastin and other proteins to slow down the aging process of the skin. Normally, signal peptides usually have the form Palmitoyl tripeptide-5, palmitoyl pentapeptide-4, Sederma; Peptide Carrier (Carrier Peptide): This peptide plays an important role in providing trace elements such as magnesium, copper to the skin. Thereby improving collagen production, increasing skin elasticity and firmness. In addition, the use of this peptide has been shown to reduce signs of aging, destroy age spots on the skin; Enzyme Inhibitor Peptide: Derived from protein in rice, soy, has the effect of inhibiting hyperpigmentation, retaining more collagen to help whiten and youthful skin.

3. The effect of peptides on the skin
3.1. Anti-aging, smooth wrinkles
The most important effect of peptides on the skin is to increase collagen production, which helps to prevent aging, effectively smooth wrinkles. However, with age, the production of peptides weakens and collagen synthesis slows down. This makes the skin no longer shiny and smooth as before.
Therefore, there are now a lot of anti-aging skin care products with peptides as the main ingredient, helping us to add peptides to the skin from the outside.
3.2. Provides copper element for skin
The trace element copper has been shown to be effective in healing skin lesions. Some peptides have copper molecules in their structure, which act on tissues to increase wound healing. Copper-added peptides are found in many natural skin care products.
3.3. Reduce skin redness
Carnosine and N-acetylcarnosine peptides both have the ability to help reduce skin redness or rashes. Besides, they also have extremely good antioxidant properties, which help inhibit the inflammatory process on the skin.
3.4. Increase elasticity
When the skin possesses more peptides, the production of collagen increases and helps the skin become more firm. In particular, the most important peptide is trifluoroacetyl-tripeptide-2, which has the ability to help reduce sagging and increase skin elasticity.

3.5. Features like Botox
Uses of Peptides will include the ability to block the transmission of signals from nerves to facial muscles. In particular, Neuro Peptide or Argireline are two types that have been shown to have the ability to block conduction on nerves. As a result, it prevents muscle contraction, making the skin smooth similar to Botox.
4. Notes when using Peptide
Because Peptide is a structural protein component, it becomes an important ingredient in anti-aging and skin care products. Different peptides will have different methods of combining in the same product, helping to thoroughly overcome skin aging problems;
The effect of Peptides on the skin is higher if they are preserved in the right way. Due to the nature of amino acids, light and air are factors that are easy to degrade peptides. Therefore, the best condition is to store the Peptide in an airtight container, in a cool place away from direct sunlight;
Peptides when added externally can cause irritation to a certain extent during use. Therefore, users need to learn carefully, before deciding to use any skin care products containing Peptide. If irritation occurs, you should stop using the product immediately.
