In the advertisement of skin care products, there are always various "catchwords" or ingredients. Like the first Dabao SOD honey, SOD is an antioxidant (superoxide dismutase, also known as liver protein, Ogulin, or sod for short). These "catchwords" or ingredients will show powerful functions that can't be ignored in advertisements, many of which are called "miracles". For example, lamer, who recently provoked lawsuits, advertised their products "to let the founders suffering from facial burns reply to the past (lamer advertising words)". However, with the gradual understanding of science and technology, product technology and ingredients in skin care products, we gradually realize that it is the most important to understand our own skin information and find the right ingredients for ourselves. Despite the fact, we always have countless impulses to use some products that seem to be "miracles".

But in fact, not all advertisements are fallacies. In fact, many effects are verified by professionals in actual experiments. For example, the recently hot skin care ingredient "polypeptide", which leads to the topic of today's discussion: polypeptide in skin care products! Polypeptide is widely believed to help prevent the loss of collagen and promote its formation (can help reduce the appearance of wrinkles and fine lines). This hot skin care ingredient has been introduced into stores by cleansing, essence, facial cream or facial mask. But what does polypeptide actually do? Or is it just for the purpose of combining with the recently popular "collagen" for publicity? We analyzed the literature of three industry-leading dermatologists in Beverly Hills, and we have to say that the function of polypeptide is really amazing!

1. What is polypeptide?

Polypeptides are simply: small compounds composed of short chain amino acids, which are the basic components of proteins. Compounds composed of 20-50 peptides become polypeptides.

What is the reason why peptides are widely used in cream and cream?

Peptides are basically fragments of proteins. Therefore, when they are used in skin care products, the purpose is to let those collagen fragments stimulate the growth of collagen. Intact, non fragmented proteins, such as collagen, cannot be absorbed directly through the epidermis of the skin, so these smaller fragments can penetrate into the cells.

2. How do peptides work?

When used in skin care products, peptides can be divided into three categories: signal peptide, carrier peptide and inhibitory neural signal peptide.

By acting as a messenger, signal peptide can trigger the synthesis of collagen, thus increasing skin firmness. It's easy to understand that when collagen breaks down, polypeptides act as an alarm system, informing our bodies to make more collagen to help replace what we naturally lose as we grow older. Therefore, the direct use of polypeptide containing products on our skin can play a role of pretending to alarm, inducing our skin to think that it has lost collagen and needs to produce more.

Carrier peptides help to stably transport trace elements (such as copper and manganese) into the enzymatic reaction, which plays an important role in promoting the synthesis of collagen and elastin, the growth of new blood vessels and wound healing. Inhibition of neural signaling peptide can soften fine lines caused by muscle movement, just like local Botox. To sum up, using peptides for your skin is a way to let your skin know that it has depleted collagen and to produce and store more collagen.

3. Peptides need the benefits of advertising

Although other skin care hero ingredients, such as retinol (which helps keep the skin active and young), can cause skin redness, peeling or irritation. But in the use of polypeptides, there are only benefits, no side effects.

Peptides can stimulate collagen production in the dermis, making the skin healthier, smoother, less wrinkled and more delicate.

The loss of collagen, like the collapse of the scaffold inside the skin, will cause skin sagging and aging. For inhibitory neuropeptides, they break the communication between nerve and muscle, so if these muscles do not contract, they will reduce wear and make wrinkles slower, such as crow's feet and forehead.

4. Polypeptides really have no disadvantages?

First, using peptides is a long-lasting battle. It can be seen from the way they operate that polypeptides will not be as effective as acids and alcohols. It will take at least a few weeks or even longer to see the effect. Secondly, the natural defense mechanism of skin is to exclude bacteria and other toxic molecules. So can polypeptides be absorbed by touching the skin? The answer is: it's not easy. However, in order to solve these problems, scientists have been using various technologies, such as modifying peptides with palmitoyl and fatty acids, which can effectively enhance skin absorption, about 5-10 times as much as the original. Generally, the peptides that have been very effective will become particularly effective in skin care after modification.

5. How to choose the right product?

In order to make the polypeptides of skin care products truly play the claimed magical effect, skin care products should have the following characteristics:

• Peptides must be present in stable skincare products, so they will not continue to be broken down.

• Peptides should be present in formulas that allow them to easily penetrate the skin barrier.

• The amount of polypeptide contained in the product is enough to produce a reasonable clinical effect.
