“I” is a peptide, which was initially used in the medical field. One day soon after seeing the biological activity of “I”, the skin care industry also began to attack our family.
From the acetyl hexapeptide-8 added to LA MER eye cream and Estee Lauder Sculpture Essence, to the favorite blue copper peptide essence, and the main oligopeptide-1 of HFP oligopeptide stock solution, our family can be regarded as a winner. What does this professional and advanced term represent? Today, I will introduce our peptide family to you in a simple and simple way.
Speaking from the peptide family
Amino acids are the basic elements that make up “I”. If you compare amino acids to bricks, then “I” is the room, and protein is the building.
Our family is very large. According to the number of amino acids, it is divided into dipeptides (contains two amino acids), tripeptides (contains three amino acids), tetrapeptides (contains four amino acids), etc. Family members with less than 10 amino acids are relatively stable Plane structure.
A substance composed of more than 50 amino acids does not belong to our family members. It is a protein called a “building”. For example, EGF contains 53 amino acids. The protein has a large molecular weight and is a less stable three-dimensional structure, so it is mostly stored as a freeze-dried powder; and it is more difficult to be absorbed under normal skin barrier conditions, and the effect of breaking the skin will be better.
In order for the “I” to function better, the R&D engineer must first find a way to let the “I” pass through the cuticle of the stratum corneum and reach the deep layers of the skin.
What should I do if I am “intercepted”? Find a “friend” who is stronger than you and drag you. Palmitoyl and acetyl, which often appear with members of our family, play this role. Or wrap “us” with lipid components. With the help of these “friends”, the penetration rate of “us” can be increased by 100 times or more.
Of course, each family member has a unique composition structure, and different composition structures determine the different “personality” of “we”.
An analysis of the “personality” of family members
Botulinum toxin components represented by acetyl hexapeptide-8
I believe everyone is familiar with Botox. It seems to have the magic of fast wrinkle removal. The only drawback is that it is very strict in dosage control. The mechanism of action of botulinum toxins represented by acetyl hexapeptide-8 in our family is similar to that of botulinum toxin, so they are called smear botulinum.
For example, after receiving external stimuli, the nerves and muscles will “dry” together. But sooner or later, you have to pay it back when you come out. If you get too dry, you will easily get wrinkles. Acetyl hexapeptide-8 can block the nerves to give orders to the muscles, so that the muscles can restore the usual calm, and wrinkles are not so easy to form. Estee Lauder’s Sculpturing Essence, Petrov Anti-Wrinkle Firming Eye Cream, Filorga Renewing Time Eye Cream, etc. have all added this type of ingredient.
Whitening ingredients represented by nonapeptide
The “nine brothers” of our family-nine peptides are generally claimed to have whitening effects. The most frequently used one is nonapeptide-1.
After being irradiated with ultraviolet rays, a chemical reaction occurs in the skin to produce melanin. Nonapeptide-1 acts on the source of melanin production, and competitively inhibits the binding of α-MSH to the melanin corticosteroid receptor-1 (MC1-R) on the melanin cells, blocking the signal pathway of melanin synthesis, thereby reducing melanin production . This ingredient is added to the La Praire Caviar Essence Pure Series.
Regenerating and repairing ingredients represented by palmitoyl pentapeptide
Palmitoyl pentapeptide is a fragment of collagen that constitutes the most abundant protein in the skin. It is called “microcollagen”, which can effectively stimulate or induce collagen production and inhibit collagen degradation. Palmitoyl pentapeptide-4 is the classic skin care ingredient of P&G Olay.
Anti-inflammatory and repairing ingredients represented by palmitoyl tetrapeptide
The skin protects the human body from external damage and irritation. Once it receives external stimuli, the immune system activates signals to release inflammatory factors, which in turn causes a series of itching, sensitivity, redness and swelling. 80% of skin problems are related to inflammation. Palmitoyl tetrapeptide is known as the “youth hormone peptide”, which can inhibit the release of inflammatory factors and reduce the damage of inflammation to the skin.
Breaking through the boundaries of traditional skin care, “I” hopes to lead our family to start a new revolution in the field of beauty and skin care.
