After many years of research, peptides scientists finally gave green light to add peptides in skin care products. Some peptides are naturally produced into the human body, others may come from external sources.
They have a variety of functions. When it come to skin care the research already identified and determined what you need to make it firmer and more radiant. Here you can learn exactly what peptides are to assure you make the right choice.
The basics about peptides
Peptides are molecules formed as a chain of amino acids that are bound together to form cells of the body, proteins, antibodies, hormones, enzymes, or nerves. Pretty easy! But if you have not checked your knowledge in chemistry lately, you might get a little lost among chemical terms. So let's take a look at some terms to make sure you fully understand it.
- Molecule: a group of atoms that create a chemical compound that is able to produce a chemical reaction.
- Amino acids: compounds considered as building blocks of proteins. It is possible to find up to 20 of them in the human body.
- Protein: proteins are organic compounds made of large molecules containing chains of amino acids and peptides.
As you can notice, peptides are an essential component of substances produced into the human body. So, simply put, peptides are the very basic compound of them and their smallest molecules. When they organize several amino acids as a chain, they can create a protein.
Where can you find peptides?
You can find peptides in all living organisms, animals, plants and humans, that also have molecules of proteins. In the human body, they are mostly distributed among body tissues such as skin, muscles, hair, nails, etc. Nowadays, it is also possible to find synthetic peptides. Although they have some particular features, they may also provide many of the benefits of real ones.
Types of peptides for skin and how they work
In general, peptides have the ability to penetrate faster, deeper and more easily human cells. That is due to their smaller size when compared to protein and other molecules. They have several classifications. The most outstanding for the skin are related to the number of amino acids and those related to their functions, as follows:
Peptides by number of amino acids
- Oligopeptides: peptides with chains of twenty amino acids or less.
- Polypeptides: peptides with chains of amino acids between twenty and fifty.
Peptides by function
- Carrier/transporter peptides: they transport minerals that are too heavy, slow or difficult to deliver to specific parts of the body.
- Signaling peptides: these peptides send signals to stimulate a biological response to create more substances by the human body. For instance, to produce more collagen to make the skin firmer. Also, hyaluronic acid that increases hydration or elastin to improve flexibility.
- Neurotransmitter peptides: these inhibit brain neurotransmitters in order to cause a natural “Botox” effect. As a result, the skin looks wrinkle-free.
- Antimicrobial peptides: they kill damaging bacteria and result very useful to treat acne and heal wounds.
What do peptides in skincare do?
Nowadays, you can find many skincare products promoting peptides as part of their formulas. But what exactly are they and how do they work when added to skincare products? That is the answer you will find here.
Understanding peptides
Peptides are the smallest molecules of substances and cells you can find into the human body. Such substances include proteins, antibodies, hormones, enzymes, or nerves distributed all around the body. They are formed as chains of amino acids that are bound together to form cells. They are the very basic compound and due to their tiny size, they can penetrate the deepest layers of the skin and cells.
Are there special peptides for skincare?
There are several types of peptides. When we talk about them for skincare we refer to those that are used in skincare products and what their functions are. Overall, peptides work to stimulate the production or transportation of substances through tissues and cells of the body.
Due to their small size, they have the ability to penetrate deeper and faster than other components. For instance, that is what they do with collagen when this substance reduces its production.
Depending on the peptide and the message it has, collagen can increase its production or can be transported to certain areas. In this sense, these are the peptides that mix with skincare products and offer you great benefits.
- Carrier/transporter peptides: they can transport substances that are too heavy, slow or difficult to deliver to specific parts of the body.
- Signaling peptides: these peptides send signals to stimulate a biological response to create more substances by the human body. For instance, to produce more collagen to make the skin firmer. Also, hyaluronic acid that increases hydration or elastin to improve flexibility.
- Neurotransmitter peptides: these inhibit brain neurotransmitters in order to cause a natural “Botox” effect. As a result, the skin looks wrinkle-free.
- Antimicrobial peptides: they help to kill damaging bacteria which results very useful to treat acne and heal wounds.
Benefits of adding peptides to skincare products
- You can see faster results to improve specific concerns of your skin
- Can Increase the production of collagen and hyaluronic acid
- Your skin can become firmer and toned
- It reduces the visibility of wrinkles and the formation of new fine lines
- It mixes well with many other skincare ingredients
- It is safe to use even in sensitive skins and rarely have secondary effects
Can everybody include peptides in their skincare routine?
Including peptides in skincare products work to improve the impact of other ingredients such as collagen. In this sense, if you want to use peptides, you must pay attention to the ingredients included in the formula.
That is because it is what you will get. On the other hand, peptides are pretty safe to use and rarely cause allergies or any other reaction. However, it is always recommended to consult with a doctor if you use peptide for the first time.
To sum up, peptides are the solution to speed up the results of your skincare routine in a safe way. Most importantly, they help to deliver real effects to make your skin more toned, firmer, and fresher.
Final words
Now that you already know the basics about peptides, it might be time to fin the best option for your skin. They are safer and more effective than many other ingredients in the cosmetic industry. The key is to find the type of peptide that matches your skin´s needs.
