What Are Peptides?

Peptides are chemical compounds that contain amino acids; they're also referred to as polypeptides. Amino acids are the building blocks of proteins that the human body requires for optimal functionality.

Due to their ability to provide numerous improvements to the skin, peptides are often used in many facial serums.

What is Peptide Serum?

A serum is a mixture of various ingredients that is often intended to improve the appearance of the skin. Serums are typically used on the face.

Serums typically contain ingredients that penetrate deeply into the skin in order to reverse common skin problems. Peptide serum is a specialized mixture of peptides and other ingredients that work synergistically to improve your skin.

Many skincare products contain peptides as one of the primary active ingredients.

Types of Peptides

There is more than one type of peptide that is used in skincare serums, including:

  • Copper peptides: This is one of the most popular peptides used in beauty products for skin and hair. Copper peptides increase blood flow to the hair and skin, which stimulates the flow of oxygen, therefore improving the overall health of skin and hair. Copper is also responsible for the maintenance of hair color and, in some cases, it can prevent hair from turning gray.
  • Signal peptides: This is another popular peptide used in beauty products due to its ability to send signals to the cells in various parts of the body in order to accelerate the production of collagen, making the skin look more youthful in the process. You will find this type of enzyme in many facial serums.
  • Enzyme inhibitor peptides: These peptides can smooth the muscles in the face and neck areas, helping to reduce the appearance of lines and wrinkles. This is accomplished due to the enzyme inhibitor peptide's ability to suppress the production of a certain protein that leads to wrinkles and lines.


When choosing a peptide serum, you may want to review the ingredients to see which type of peptide is used.

What Does Peptide Serum Do?

The most notable thing about peptide serums is that they can help your skin look younger. Peptide serums help to make the skin more supple and smooth, as it minimizes the appearance of fine lines and wrinkles.

Peptide serums address aging, discoloration, and hydration concerns

Peptide serum also does the following:

  • Provides a barrier of protection: The natural barrier of the skin protects it from the dangers of UV rays, bacteria, toxins, and more. However, this barrier can be compromised by exfoliating too frequently or too harshly, exposure to toxins, cigarette smoke, or even inadequate sleep. Peptide serum helps to fortify this barrier, therefore, protecting your skin from the many dangers that exist in the environment.
  • Collagen production: Peptide serum encourages the skin to promote the production of collagen, which is a protein that the body naturally produces. However, as a person ages, collagen production becomes diminished, which is why the skin begins to sag and lines and wrinkles become more prominent. However, with the help of a peptide serum, those wrinkles and lines are filled in, making a person appear more youthful.
  • Increased skin elasticity: Not only does peptide serum promote the production of collagen, but it also promotes the production of elastin fiber, another protein that is essential for the skin. With the increased production of elastin, the skin appears tighter and firmer.
  • Reduction of inflammation: Peptide serum also soothes inflamed skin, evens out your skin tone, and repairs damaged skin. So if you're dealing with hyperpigmentation, peptide serum can be instrumental in evening out your skin tone.
  • Treats acne: Those with acne-prone skin may find peptide serum especially beneficial, because some peptide serums contain anti-microbial properties, which can rid the skin of any acne-causing bacteria.

Does Peptide Serum Work?

Extensive research has been conducted on serums with peptides and its ability to effectively help with multiple skin concerns, and it has been shown that peptide serum can help address wrinkles and other signs of aging.

Unlike some other components in facial rejuvenation products, peptide serum does not simply sit on the outer layer of the skin. Peptide serum thoroughly penetrates into the deepest portions of the skin, which is where it has been proven to go to work on improving facial imperfections in a multitude of ways.

What to Look for in a Peptide Serum

With all the choices available for peptide serums, it can be overwhelming when searching for a peptide serum for your face that can help with your skin concerns. So, how do you choose?

First and foremost, you should check that some type of peptide is listed on the primary, active ingredient list. If "peptides'' isn't one of the key ingredients in the product, then you may want to look into other options.
Some other important qualities to look for in your peptide serum include:

  • Hydrating qualities
  • Lightweight formula
  • Clinically-proven ingredients

You also want to ensure that you choose a serum that isn’t likely to cause negative reactions. For those with highly sensitive skin, some peptide serums can lead to breakouts and rashes—like most other types of skin care treatments. You can find peptide serums that are gentle on sensitive skin, like Colorescience products.

How to Use a Peptide Serum

Even if you've never used a facial cream before, it's not difficult to use peptide serum. You can simply add it to your regular facial regimen fairly easily. You’ll simply need to pump it out of the bottle and gently apply it to your face

The key to using peptide serum is to make sure you apply it to freshly washed skin. So, after you’ve used your cleanser. After you've washed and exfoliated your face and neck area, apply your toner, then the peptide serum according to the instructions on the label. Next, you should apply a moisturizer.

When to use peptide serums

If you're typically sensitive to skin care products, you might want to perform a patch test before applying the serum to your face and neck area. To do this, apply a small amount to your inner wrist and wait 24 hours. If you haven't experienced a reaction, then you should be able to safely use it on your face.

When to Apply Peptide Serum

It's safe to use your peptide serum twice a day, if you desire, but once a day can suffice. However, how often you use it depends on the skin conditions you’re trying to address, your skin care regimen, and how quickly you want to see results. Often, more frequent use can help you see results faster. Generally, people notice results with consistent use of peptide serum in about 1-3 months.
