Pros And Cons Of Peptides For Skin Care

Hydration for skinAlong with antioxidants, peptides are ingredients that are being discussed most in terms of their anti-aging skin care benefits.

Peptides are effective components that are able to boost collagen and offer many other benefits for the skin. But does peptides’ use for skin care have only advantages or disadvantages as well?

In this article, we will find answers in different questions about peptides including what they are, how they work, whether they are effective as well as peptides´ pros and cons for the skin. Are peptides overrated when they are called miracle anti-aging ingredients and do they really work? Let´s find out!

Peptides in a few words

Peptides are amino acid chains. Amino acids are the structural components of proteins and their role is to transfer nutrients to adjacent cells. Amino acids form short or long type chains that are called peptides.




When peptides form longer amino acid chains, they create proteins, the ¨material¨ by which internal organs, tissues and of course the skin is created.

Collagen is a protein as well and it is actually the most important factor for a youthful, toned, smooth and vibrant complexion. Imagine that 75% of the skin is made of collagen.

Why Are Peptides Important In Skin Care?

The peptides that are contained mainly in anti-aging skin care products reinforce the natural proteins, which already exist in the skin but their production reduces over the years, so that the skin stays healthy and youthful for a longer time.

A lot of times, peptide creams or peptide serums that are available in the market contain a combination of peptides because different types of peptides are best for different functions. For example, there are peptides that smoothen the wrinkles, some that repair the protective barrier of the skin while others increase skin firmness and its levels of hydration.

How Do Peptides Work In The Skin?

As we have already mentioned, peptides are the ones that send signals to the cells asking for the repair mechanisms to be activated. Let’s take, for example, collagen, a protein made from long chain amino acids.

Collagen is continuously attacked by both external and internal deteriorating factors which lead to its breaking into amino acid fractions. These pieces are actually peptides that have a specific role, to alert fibroblasts in order to quickly synthesize new collagen and repair the damage it has been inflicted.

In young skin, the signals that the peptides send to the cells almost always reach the recipient, and the regeneration process takes place normally. However, as we age, the communication between the peptides and the cells starts deteriorating and the signals that the peptides send either fail to reach their destination or are not sent at all.

That is how the collagen’s support wears down without new collagen being created and so gradually wrinkles and signs of skin sagging start appearing.

The synthetic peptides that are contained in the skin care products we buy are there to sort out this problem of the difficulty in communication between the peptides that exist naturally in the skin and the cells.

Without necessarily penetrating the deeper layers of the epidermis, those synthetic peptides manage to send repair signals to the cells.

Due to their biomimetic action (they imitate the function of natural peptides,) they essentially trick the cells into ordering the fibroblasts to synthesize more new collagen fibers to make up for what it has been worn out.

Other Pros of Peptides for Skin

Peptides do not only boost collagen but based on the number of amino acids they contain and their molecular weight, they are distinguished in oligopeptides such as dipeptides, tripeptides, pentapeptides, hexapeptides, e.t.c) and polypeptides.

For example, some peptides are very effective moisture-binding agents while others block the messages sent by the neurotransmitters to the facial muscles, thus preventing recurring contractions from forming into wrinkles of expression.




In general, the role of most peptides is to facilitate the cell communication and through the signals that they send to help the skin function better.

Cons of Peptides

As active ingredients in cosmetic compositions, peptides are considered to be safe as they rarely cause irritation even on sensitive skins. They are, however, sensitive themselves as ingredients and may degrade if they are not protected from the light and air. That is why, peptides are often contained in pump bottles and not jars.

Also, the benefits they provide to the skin may not become immediately visible, but in some cases even a month is needed for you to enjoy more visible results.

The cost of those products is another con with some of them being quite expensive, but you can surely find good quality peptide serums and creams that are effective and customer friendly when it comes to their cost.

Do Peptides Work In Skin Care?

Peptides on their own cannot do miracles when it comes to completely getting rid of wrinkles and skin sagging but when they get combined with other active ingredients, they are very effective fighting various signs of skin aging.

Their benefits for the skin are surely recognized by cosmetic research with new types of peptides or peptide combinations being discovered every day, so in the future we may be able to enjoy even more advanced and effective peptide formulas.

In conclusion, peptides are here to stay as effective anti-aging ingredients, and in this article we have seen various aspects of their function, pros and cons as well as how they work to provide our skin with plenty of different benefits.
