Peptides in Skincare – Everything You Ever Wanted to Ask


Peptides are a hot topic when it comes to skincare. This is because peptides have many potential skin benefits. In this article, we discuss what peptides are, what peptides are put in skincare products, and the potential benefits of peptides like copper peptides and ipamorelin for the skin. We will also explore how peptide skin products are used and whether or not they actually work!

What are peptides?

Not to get all scientific on you, but peptides, like melanotan 2 and oxytocin, are chains of amino acids. These amino acids are the building blocks of proteins, which are essential for every single cell in our bodies. Peptides can be found naturally in our bodies and even occur naturally in some foods. For example, peptides are found in soybeans and milk products.

In fact, everything from our muscles to our skin is made up of peptides. Peptides play a major role in our body’s processes, from cell signaling to tissue repair. Peptides are also involved in producing collagen, a key protein for youthful, healthy skin.

Peptides in skincare

Regarding skincare, peptides are often touted as being anti-aging or skin-rebuilding ingredients. This is because peptides can stimulate collagen production, essential for keeping skin looking young and plump. Peptides can also help repair damaged skin cells, but we’ll get into the potential benefits later.

Many different peptides are used in skincare products, but here are some peptides believed to have skin benefits:

  • Palmitoyl tetrapeptide-seven: is known for its anti-inflammatory and skin-healing properties.
  • Matrixyl 3000: a peptide blend that has been shown to stimulate collagen production.
  • Acetyl hexapeptide-eight: Like Botox, this peptide can help relax wrinkles and fine lines.
  • Ipamorelin: a peptide that can help improve skin tone and elasticity.
  • ll 37 peptide: a peptide that can help reduce inflammation and improve skin healing.
  • Acetyl hexapeptide-eight: This peptide can help relax wrinkles and fine lines.
  • Palmitoyl oligopeptide: This peptide can help stimulate collagen production and improve skin elasticity.
  • Copper peptides: Copper peptides can help repair damaged skin cells and promote collagen production.

Ipamorelin and 11-37 peptide

While not technically peptides, these peptide-like compounds are often used in skincare products. Ipamorelin is a peptide that helps stimulate growth hormone production. Growth hormone is involved in cell regeneration and repair, so ipamorelin is said to have the potential for anti-aging.

On the other hand, 11-37 peptide is another peptide-like compound that is said to help with wound healing. 11-37 peptide is often used in products for people with scars or other skin damage.

Unfortunately, more study is needed to see if these peptide-like compounds have statistically significant benefits for the skin. This basically means we’re not scientifically sure if these peptides work yet!

What are the benefits of peptides for the skin?

Now that we know what peptides are and where they come from, let’s discuss their potential and reported benefits. Peptides can have a variety of potential benefits when applied to the skin, including:

They stimulate collagen production.

Let’s start with the most well-known peptide benefit: stimulating collagen production. Collagen is a protein that gives our skin its structure and elasticity. It’s produced naturally in our bodies, but production slows down as we age due to factors like sun damage and pollution.

This is where peptides come in! Peptides like matrixyl 3000 and copper peptides help stimulate collagen production, resulting in firmer, smoother skin. They do this by signaling to our cells that they need to produce more collagen.

They help repair damaged skin cells.

Damaged skin cells are caused by sun damage, pollution, and inflammation. Peptides like 11-37 can help repair these damaged cells by reducing inflammation and promoting a major cause of wrinkles and fine lines.

Of course, peptides can’t completely undo the damage already done. But they can help improve the appearance of skin by repairing some of the damage.

They help improve skin tone and elasticity.

Part of peptides’ collagen-stimulating properties includes improving skin tone and elasticity. This is because peptides help our skin cells produce more collagen and

They help reduce wrinkles and fine lines.

Some peptides can also help reduce the appearance of wrinkles and fine lines by relaxing the muscles under the skin. Much like how Botox works, peptides like acetyl hexapeptide-eight help relax the muscles that cause wrinkles.

They help with wound healing.

Did you know that peptides can also help with wound healing? This is particularly true of peptides like 11-37, which help reduce inflammation and promote skin healing. However, topical peptides should not be used on open wounds, and studies on 11-37 peptides are still ongoing.

What are the side effects or risks of peptides?

As with any ingredient, peptides can also come with risks and side effects. Let’s go in-depth into some of the potential risks and side effects of peptides:

They can cause skin irritation.

The most common side effect of peptides is skin irritation. This is because peptides are signals that tell our skin cells to do something, and sometimes those peptides can overstimulate the skin cells.

This can result in redness, itchiness, and even breakouts. If you have sensitive skin, it’s best to avoid or patch test peptides before using them on your face.

They can cause inflammation.

While some peptides help reduce inflammation, peptides can also cause inflammation in some people. This is particularly true of peptides like 11-37, which help with wound healing. If you know you have sensitive skin, avoiding peptides known to cause inflammation is best.

They can interfere with other skin treatments.

If you’re using or considering other skin treatments like retinoids or acids. The peptides might interfere with the other treatment, or the other treatment might interfere with the peptides. Speak to a dermatologist before using peptides.

They can cause sun sensitivity.

The sun is the enemy of peptides! Depending on the peptide, it can make your skin more sensitive to the sun. This is why it’s important always to wear sunscreen when using peptides, even if you don’t normally need it.

Do peptides actually work?

The question on everyone’s mind: do peptides actually work? The answer is a resounding maybe. Peptides are a relatively new ingredient, and there’s still a lot of research to be done.

However, peptides like matrixyl 3000 and copper peptides have been shown to stimulate collagen production, resulting in firmer, smoother skin. The research done on these peptides is more extensive, which is why they’re more commonly used in peptide products.

When it comes to the effectivity of these peptides when applied topically, that’s still up for debate. The peptides in these products might not be able to penetrate the skin deeply enough to have an effect.

The formulation of the product is also important. If the peptides are in a base that doesn’t allow them to penetrate the skin, they won’t do anything and will merely sit on the skin’s surface.

Final Thoughts

All in all, peptides are a promising ingredient, but more research needs to be done to determine their efficacy. If you’re interested in trying peptides, we recommend researching peptides, peptide products, the formulation and base of the product before purchasing. And as always, patch test before using any new product on your face!
