What are Peptides & Their Types

Overview of peptides : The building units of protein in your body are called peptides. Peptides are chains that are created when amino acids combine. After being created, these peptides come together to form proteins. Your body may assemble peptides to create a variety of proteins that it utilises to create bone, cartilage, muscles, skin, hair, and other tissues. [1]


Types of Peptides

When discussing peptides in skin care, there are many types. All are unique in their efficacy and function. Therefore, treating peptides as monoliths is misleading to consumers. To understand the nuances of peptide research, you need to get technical. Here are some common types of peptides[2]:


It was the first peptide to show skin-enhancing benefits when applied topically. Matrixyl, or palmitoyl pentapeptide-3, is a pentapeptide that has been shown to stimulate collagen production.


If you’re in tune with beauty news, you may have heard that peptide creams are the new Botox. Hexapeptides can produce a mild, Botox-like effect, inhibiting the release of neurotransmitters that keep facial muscles from forming wrinkles.

Palmitoyl Oligopeptide :

For those seeking barrier support, this peptide might be of interest. It not only promotes the production of collagen and hyaluronic acid in the skin but also helps protect the skin from the damaging effects of UV rays.

Palmitoyl Tetrapeptide-7 :

Skin inflammation can cause premature aging and damage the skin. Inflammation and skin regeneration may be stimulated by this peptide.

Copper peptides :

These naturally occurring tripeptides are actually found in plasma. Supposedly, these increase skin elasticity and firmness while enhancing skin regeneration.

The Benefits of Peptides for Skin

With age, the collagen production declines. As a result, your skin sags and loses its elasticity, and you get wrinkles. Incorporating peptides into your skin care routine can help to a great extent. Here are some key benefits of using peptides for skin[3]:

Supporting collagen production:

Collagen is a protein that gives the skin its firmness and elasticity. Peptides stimulate collagen production, which helps to reduce the appearance of fine lines and wrinkles and improves the overall texture of the skin.

Improving skin texture:

They have been demonstrated to significantly improve the texture of the skin by enhancing the proteins in your skin, particularly assisting in the reduction of fine lines and wrinkles. Also, as it produces neurotransmitters that relax facial muscles, argireline may lessen the appearance of wrinkles.

Strengthening the skin barrier:

Peptides can support your skin’s proteins. The creation of hyaluronic acid, which protects the skin’s moisture barrier and helps the skin cope with environmental stressors like UV rays, can also be stimulated by some kinds (oligopeptide).

Reduces Inflammation:

Peptides have anti-inflammatory properties that help to soothe and calm irritated or inflamed skin. This can be particularly beneficial for those with sensitive or acne-prone skin.

Increases Hydration:

Peptides help to improve skin hydration by attracting and retaining moisture in the skin. This helps to keep the skin looking plump, healthy, and hydrated.Peptides have so many essential functions that can greatly benefit anyone’s skincare routine. No matter what your goal is, there is a peptide that can help[4].

How Peptides Help to Fight Acne-Prone Skin?

How peptides can reduce inflammation and bacteria that cause acne
Peptides have been shown to have anti-inflammatory and antibacterial properties that can be beneficial for reducing inflammation and bacteria that cause acne[5]. Here’s how peptides work to reduce inflammation and bacteria:

  • Anti-Inflammatory Properties: Peptides reduce inflammation by blocking the activity of enzymes, which produce inflammatory mediators. Blocking their activity calms irritated skin.
  • Antibacterial Properties: Peptides have antibacterial properties that may help reduce acne-causing bacteria. Studies have found some peptides to have a direct antimicrobial effect on bacteria, potentially reducing bacteria on the skin and preventing new acne lesions[6].
  • Promote Wound Healing: Peptides can also help to promote wound healing by stimulating cell growth and tissue repair. This can be beneficial for healing acne lesions and reducing the risk of scarring.

Peptides for Fine Lines and Wrinkles

How peptides can stimulate collagen production and reduce the appearance of fine lines and wrinkles
Peptides can boost the production of collagen and lessen the visibility of fine lines and wrinkles by signaling to skin cells to produce more collagen. Collagen is a protein that provides structure and elasticity to the skin. As we age, our skin’s ability to produce collagen decreases, which can lead to the formation of fine lines and wrinkles[7].

In a double-blind clinical study, 20 women aged 40 to 62 were studied. They were given a formula containing 3% collagen-like peptides and 1% booster molecules. The gel was applied to their eye area for four weeks. The results showed a significant reduction in the surface as well as the depth of wrinkles[8].Specific peptides that are effective for aging skin.

Peptides for Hyperpigmentation and Dark Spots

How peptides can inhibit melanin production and reduce the appearance of hyperpigmentation and dark spots
Peptides can inhibit melanin production and reduce the appearance of hyperpigmentation and dark spots by interrupting the activity of tyrosinase, an enzyme that is essential for melanin synthesis. Melanin is the pigment responsible for giving our skin its color, but when it’s overproduced in certain areas, it can lead to hyperpigmentation and dark spots.

One way that peptides can inhibit melanin production is by regulating the activity of certain enzymes in the skin that contribute to melanin synthesis. Another way that peptides can work to reduce hyperpigmentation is by stimulating cell turnover in the skin. When old skin cells accumulate on the surface of the skin, they can contribute to the appearance of dark spots and uneven skin tone.

Peptides can also help to reduce inflammation, which can be a contributing factor to hyperpigmentation. By reducing inflammation, peptides can prevent the overproduction of melanin that can occur as a result of skin damage or irritation.

Moreover, peptides can encourage skin renewal and turnover, which can aid in lightening hyperpigmentation and dark spots that have already developed. Peptides can aid in the removal of unhealthy skin cells and the development of new, healthy ones by promoting cell turnover.

How to Choose Peptide Products?

What to look for in peptide products, including specific peptides and concentrations
There are so many products on the market containing peptides that it can be hard to know where to start. Here’s how to shop for peptides,

  • Peptide Type: Look for products that contain peptides that are known to be effective for your specific skin concern. For example, if you are looking for anti-aging benefits, look for products that contain peptides such as palmitoyl pentapeptide-4 or copper peptides.
  • Concentration: The concentration of peptides in a product can vary widely, and higher concentrations are generally more effective. Look for products that contain at least 3-5% peptide concentration for maximum effectiveness.
  • Formulation: Peptides are most effective when they can penetrate the skin and reach the deeper layers where they can stimulate collagen production or inhibit melanin synthesis. Look for products that have a formulation that allows for maximum penetration, – such as serums or creams that can be absorbed easily.
  • Other Ingredients: Products such as Antioxidants, hyaluronic acid, and niacinamide, can enhance the effectiveness of the peptides and provide additional benefits for the skin.

Tips for incorporating peptide products into a skincare routine

Peptides are simple to include into any current skincare routine because of their mild hydration-boosting capabilities and versatility to be utilized day or night. According to Ghiasi, peptides can be safely used with the majority of skincare actives, including retinol and vitamin C. But, it’s important to keep in mind that particular peptide types, such as glycolic and lactic acid, have been demonstrated to irritate skin when used with AHAs.[9].

There are several various solutions on the market that contain this collagen-boosting component, from moisturizers to serums. Nevertheless, because peptides must penetrate the skin to be effective, using cleansers with peptides that are instantly rinsed off will prevent the component from performing as intended.

Although peptides can support healthy skin, both experts emphasize the value of a comprehensive daily skincare regimen that will nourish and protect your skin. This routine should include the use of sunscreen to shield skin from UV rays, ceramides to strengthen your skin barrier, and antioxidants like vitamin C to protect skin from environmental damage.

Side Effects of Peptides and Precautions for Using Them

Potential side effects of using peptide products, such as skin irritation or allergic reactions
While peptide products are generally considered safe for use, there is always a risk of potential side effects, particularly if you have sensitive skin or are allergic to any of the ingredients in the product. Here are some potential side effects of using peptide products[10]:

  • Skin irritation: There is a possibility that peptide products can irritate the skin, particularly if you have sensitive skin. There can be redness, itchiness, and dryness associated with irritation.
  • Allergic reactions: The use of peptide products may cause an allergic reaction in some people, causing symptoms such as itching, swelling, and hives.
  • Acne breakouts: A peptide product that is not formulated correctly or is too heavy can sometimes cause acne breakouts and clogged pores.
  • Discoloration:The use of peptide products in high concentrations or for extended periods of time may cause discoloration of the skin in rare cases. You should patch the product on a small area of skin before using it all over your face in order to minimize side effects.


Precautions for using peptide products

Here are some precautions to keep in mind when using peptide products:

  • Patch test: Before using a new peptide product, it is essential to patch test the product on a small area of skin first. This will help determine if you are allergic to the product or if it causes any irritation.
  • Follow instructions: Make sure you follow the manufacturer’s instructions for using the product correctly, including the frequency and amount to apply.
  • Sun protection: There is a possibility that peptide products may increase skin sensitivity to the sun. It is essential to wear broad-spectrum sunscreen even if you are indoors during the day.
  • Don’t overuse: It is possible to experience skin irritation, redness, or even breakouts if you overuse peptide products. Follow the manufacturer’s recommended usage guidelines and avoid using more than is necessary.
  • Consult a dermatologist: You should always consult a dermatologist before using any new skincare product if you have sensitive skin, a history of allergic reactions, or any other skin concerns. Getting the right products for your skin type from a dermatologist can help you avoid adverse reactions.

The Best Peptide Products To Include In Your Skincare Routine

There are many peptide products that can be safely included in a skincare routine, but it’s important to keep in mind that everyone’s skin is different, and what works for one person may not work for another. Here are some peptide products that are generally considered safe for most people:

  1. Peptide serums: Peptide serums are lightweight and easily absorbed, making them a great addition to any skincare routine. Look for serums that contain a combination of peptides and other beneficial ingredients, such as antioxidants or hyaluronic acid.
  2. Peptide creams: Peptide creams are thicker and more nourishing than serums with being more suitable for those with dry or mature skin. Look for creams that contain peptides along with other hydrating ingredients, such as shea butter or jojoba oil.
  3. Eye creams: Eye creams containing peptides can be especially effective in reducing the appearance of fine lines and wrinkles around the eyes. Look for eye creams that contain peptides specifically designed for the delicate skin around the eyes.

It’s always a good idea to patch test new products before incorporating them into your skincare routine and to consult with a dermatologist or skin care professional if you have any concerns or questions.

Key Takeaways
Peptides are amino acids that are the building blocks of certain proteins needed by the skin, like collagen and elastin. Using a serum or moisturizer that contains peptides can lead to firmer, younger-looking skin and maybe even fewer breakouts. Peptides are generally considered safe, and while they’re a promising skin care ingredient, more research is needed on their efficacy.
