Peptides / Peptides

In recent years, peptides have become a true revolution in anti-aging cosmetic products. They have excellent anti-wrinkle properties, strengthen the barrierof the skin and contribute to its more youthful appearance. Like other active substances peptides are natural part of the human body and have various beneficial for skinour functions.

Withalso like proteins, these molecules is oformst at the linking of different amino acids. The use of to them in cosmetics have endless benefits. They bind dermata and the epidermis and enhance the regeneration process of the tissues. This makes them one of the favorite ingredients for natural reduction of signs of aging, among many other applications. Do you want to discover all the advantages of this very trendy ingredient? In what way can contribute to perfect skin and hair? Continue reading the following lines and you will find the answers to these questions!

What are peptides?

Molecules with regenerative properties that arise from the combination of different amino acids are called peptides. Simply put, these are protein fragments that fight aging. These molecules naturally occur in our body and have antibiotic and hormonal functions. Additionally, they act as neurotransmitters and alert the body that it needs to produce certain healing substances when there are wounds. They also minimize skin lesions caused by sunlight and act as antioxidants.

Advantages and benefits for the skin

Peptides play a very important role in our body and are part of the proper functioning of metabolism. However, as we age, our body loses this regenerative capacity and mimic lines appear on the skin. After the age of 20, on average 1% less collagen peptides are generated each year, and by around 40 years old their production almost completely stops. Peptides are the logical solution for skin rejuvenation. The main advantage of these molecules is that they are extremely effective even at low doses. As a natural component of the body they act directly on the skin in a natural way.

The higher the collagen production, the younger the skin looks. The role of peptides is precisely to stimulate collagen generation. Here are the other benefits they bring:

• Since they are neurotransmitter inhibitors, they cause the muscles to relax. In this way visibly reduce wrinkles and expression lines, caused by the continuous movement of the face;
• They correct signs of photoaging and soothe inflammatory processes in the skin caused by the sun;
• They stimulate fibroblasts, which increases collagen production by about 80%. They raise levels of elastin fibers, keratin, fibronectin, and hyaluronic acid, which improves hydration;
• They increase skin elasticity;
• They soften the complexion;
• Their antioxidant power neutralizes damage caused by free radicals.

Which types of peptides are used in cosmetics?

Peptides arise from the union of two or more amino acids. When more than 50 amino acids are grouped, we speak of proteins. The number of amino acids linked by peptide bonds determines the types of peptides. In this sense, we find oligopeptides (fewer than 10 amino acids) and polypeptides (between 10 and 50 amino acids). The oligopeptide group includes dipeptides, tripeptides, tetrapeptides, pentapeptides, hexapeptides, and octapeptides. Depending on the type of peptide used, different benefits for the skin can be extracted.

• Peptides in which only two amino acids are linked are called dipeptides. They are responsible for stimulating laminin and collagen types IV, VII, XVII.
• Tripeptides arise from the union of three amino acids. They can also be identified as “restorative” or copper peptides (GHK-Cu), as they bind to copper ions. When they penetrate into dermata, they enhance collagen production and improve cellular processes. They have antioxidant action and accelerate the wound healing process.
• Tetrapeptides consist of four peptides and have the property of improving skin elasticity. In addition they inhibit collagen loss and stimulate its production.
• The binding of five amino acids in pentapeptidespromote the reduction of wrinkles, especially in the eye area. This chain of amino acids participates in the formation of collagen and elastin in the skin.
• Hexapeptides are among the most important in the world of cosmetics because the union of six amino acids turns them into inhibitors of neurotransmitters. This helps stop expression lines. These molecules relax muscles and prevent movement, which leads to skin tightening and a significant reduction in wrinkles. The most common hexapeptides are argireline or argirelox.
• Octapeptides perform the same functions as other oligopeptides by acting directly on neurotransmitters. They arise from the union of eight different amino acids.

How exactly do peptides work against wrinkles?

Among the peptides listed above, there are those that reduce expression wrinkles in the same way that botulinum toxin (known as Botox) works.

Neurotransmitters are substances (molecules) that allow information to "travel" between different neurons, both in muscles and glands. They act on the synaptic connections of neurons. When the synapse is between the neuron and the muscle, this neurotransmitter is called acetylcholine.

The complex of argireline or argirelox(hexapeptides) e responseen for the "capture" of acetylcholine. In this way, the neuron-muscle information is interfered with and does not allow the muscle to move, and the wrinkle disappears. The muscles relax and thus the skin becomes smoother, as with the injection of botox.

How do biomimetic peptides work?

They are called so because their structure resembles the peptides naturally found in the body. They act directly on the skin tissue. This type of peptides protects cellular DNA from aging and supports cell recovery. They have antioxidant action and stimulate the production of collagen fibers.

Used correctly, peptides can be powerful weapons in the fight against aging. They stimulate cell renewal and regeneration and are suitable for all skin types. Make room for products containing this beneficial ingredient, in your daily skin care and take advantage of advantages her.
