Are Peptides Anti Aging? 5 Scientific Benefits

Peptides can sound like an intimidating thing. Perhaps to some, they seem like something that only doctors can comprehend or something that only scientists can put to good use. But in reality, peptides are accessible to anyone who what's to push their skin care routine to the next level.

Peptides are quite simply: amino acids that make up certain proteins needed by the skin. Peptides can be found all around us, and in us. In the human body, peptides are found in every cell and tissue and perform a wide range of essential functions. So this is something our body is familiar with and knows what to do with.

But as we age, our bodies slow down with certain processes, and adding peptides can help send messages to our skin that it's time to pick up the pace on making collagen and the repairing process.

While we know that some ingredients cannot penetrate the barrier of the skin, peptides can and in doing so, can make amazing things happen once they're absorbed. They're small and easily absorbed, and you'll find out, very beneficial in solving a variety of skin care issues and offering a list of important protections.

And what happens when peptides do penetrate the skin? They act as messengers for the other cells — they send signals telling the cells to produce collagen and elastin.

5 Peptide Anti Aging Benefits

Peptides topical benefits are mainly anti-aging. If you’re looking for a skin care products that promote firm, smooth skin, then try out peptides in your skin care routine. Here are some of the many benefits of peptides.

  1. Increase collagen synthesis

This is a big one because there’s a lot of hype surrounding collagen and whether or not skin care can successfully promote collagen production. While it’s still unclear whether skin care can help skin create more collagen, peptides have been proven to stimulate and renew collagen as well as decrease collagen breakdown.

  1. Smooth wrinkles

A little goes a long way with peptides in terms of smoothing out fine lines and wrinkles. With just 3% of peptides in a topical formula, research participants experienced highly significant antiwrinkle effects. Because they have properties similar to collagen and they occur naturally in the skin, peptides are able to affect the skin on a deep, intense level.

  1. Increase firmness

Firmer, more elastic skin is another anti-aging benefit of peptides. This is because peptides may a major role in the structure of skin. Without peptides, skin doesn’t remain intact, causing skin to become saggy. Topical peptides reinforce the building blocks of skin, allowing skin to keep its shape, firmness, and elasticity.

  1. Strengthen skin

Peptides aren’t alone in skin. They go hand in hand with other proteins like elastin and keratin. Over time, the amount proteins in the dermis is significantly reduced, and skin begins to decline. Peptides can strengthen the proteins and connective tissue in the dermis that allow skin recover from injury and maintain its structure, making skin stronger.

  1. Improve texture

Another benefit of peptides has emerged recently, and it's the effects on photoaging skin. When skin is chronically exposed to radiation, skin ages prematurely. This is known as photoaging, and it can cause discoloration, pigmentation, roughness, wrinkles, dryness, and more. Certain peptides can be used to improve skin texture that has specifically experienced photoaging.

What Kinds of Peptides are There?

Peptides are actually more common and readily available to us than one might think.

We know that the benefits of peptides are significant, not just externally but also internally. Peptides are very good for our health.

We can find peptides in common foods, like eggs, milk, fish, beans, lentils, oats, soy, and wheat.

Research has shown that when eating foods with peptides, or taking supplements with peptides, we can greatly improve our health. Some general health improvements would include:

  • Lower high blood pressure
  • Kill microbes
  • Reduce inflammation
  • Prevent the formation of blood clots
  • Improve immune function

There are hundreds of different peptides all with different purposes and benefits. Some products may even contain several combinations of peptides that work together.

When looking for peptides in skin care products, look for words ending in “peptide” or beginning with “palmitoyl.” You make also see prefixes like -di, -tri, -hexa, -oligo, etc. to describe how many amino acids make up the peptide. Ex: dipeptide, tripeptide, etc. Peptides may also be classified as copper peptides and neuropeptides, which describes their chemical activity.

There are various types of peptides used in skincare products, each with its own unique function. Let's take a closer look at some of the most common types:

  1. Signal peptides: These peptides act as messengers, sending signals to our skin cells to produce more collagen and elastin. By stimulating the synthesis of these proteins, signal peptides help to improve skin elasticity and firmness.

  2. Carrier peptides: Carrier peptides work by delivering trace elements and essential nutrients to the skin cells. They ensure that these vital components reach the target cells in sufficient quantities, promoting healthy skin function.

  3. Neuropeptides: Neuropeptides are involved in regulating muscle contraction, which can impact the formation of wrinkles. By inhibiting muscle contractions, neuropeptides can help to reduce the appearance of expression lines and prevent the formation of new wrinkles.

  4. Enzyme-inhibiting peptides: These peptides target specific enzymes that degrade collagen and elastin in the skin. By inhibiting the activity of these enzymes, these peptides help to preserve the structural integrity of the skin and prevent the breakdown of these vital proteins.

  5. Copper peptides: Copper peptides have been shown to stimulate collagen production and enhance wound healing. They also possess antioxidant properties, which help to protect the skin from free radicals and promote overall skin health.

Some common names of peptides in skin care include:

Palmitoyl pentapeptide (a.k.a. MatrixylTM, MatrixylTM 3000, MatrixylTM Synthe 6, etc.)
Acetyl tetrapeptide-9
Acetyl hexapeptide 3, 8, and 20 (a.k.a. Argireline)
Acetyl Octapeptide-3
Palmitoyl oligopeptide
Tripeptide 1
Tripeptide 10 Citrulline
Silk Peptides

We hope this answers your question "Are peptides anti aging?" Peptides are great for a variety of aging skin care concerns, including fine lines, wrinkles, sagging, and pigmentation, they make a great addition to anyone’s anti-aging skin care routine.
