You know how important protein is for the body, but do you know how important protein is for skin? Like the rest of the body, protein is skin’s foundation—protein is made up of amino acids, which are the building blocks of skin.
But, what are peptides? When certain amino acids are combined, they form peptides. So, you can think of peptides as fragments of proteins that skin needs for its structure and integrity.
Because they keep skin firm, elastic, and intact, peptides are hyped for their ability to address the signs of aging and even revive aging skin. Overall, peptides in skin care keep skin looking young and promote anti-aging benefits.
Peptides are also often compared to collagen. When collagen breaks down naturally with age and exposure to the elements, segments of amino acids are formed, creating collagen-like peptides. When collagen-like peptides are harnessed in skin care, the benefits of peptides include an antiwrinkle effect—reducing and smoothing out wrinkles. 
Because they’re naturally occurring in the skin and they boost the holy grail benefit of skin care—anti-aging—peptides are becoming more popular in cosmetics. Luckily, they’re pretty easy to spot.
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.
Some common names of peptides in skin care include:
Like many skin care ingredients, peptides in skin care are usually found in nature or created synthetically. Some peptides are derived from plant sources like yeast and oat kernels.
Some research shows that natural peptides aren’t stable in water solutions, which is bad news for the majority of skin care products that contain water. This is why synthetic peptides are preferable in skin care: they’re more stable and usually more affordable.
Peptides are found in a variety of cosmetics and skin care products for their anti-aging benefits. Some peptides are mimetics of botox, so some people refer to peptides as “botox-like” ingredients. Acetyl hexapeptide or Argireline is one such peptide that is often compared to botox but has been shown to be safer than botox without sacrificing effectiveness. 
In addition to the anti-aging benefits of peptides, peptides serve 3 main cosmetic functions:
This may not sound very exciting, but the importance of cell-communicating skin care ingredients like peptides is little-known. One of the functions of peptides is to act like messengers between skin cells. This communication is vital for each skin cell to do its job properly and for all skin cells to work together to uphold skin.
Good Face Tip: Combine peptides with other cell-communication skin care ingredients like retinol and niacinamide. These ingredients work together to communicate to skin cells that it’s time to regenerate new, healthy skin cells, which creates a more youthful appearance.
We’re not talking about scraped knees and bruised arms, but peptides can promote skin healing properties when skin is damaged by external factors. Sometimes skin damage can’t be seen with the naked eye, so it’s a good idea to take advantage of the healing benefits of peptides. As part of the wound healing benefits, peptides protect against harmful growth factors and have antimicrobial properties that protect against invading bacteria and fungi. 
Without peptides, your skin wouldn’t have its structure, elasticity, or firmness. However, peptides are like collagen—they don’t stick around forever. It’s inevitable that as we mature, our skin loses some of its peptide content. Since peptides are the bonds that hold collagen together, this affects skin’s appearance in the form of fine lines, wrinkles, and sagging. Applying topical peptides in skin care products encourages peptide bonds to form, which can increase collagen synthesis and promote younger-looking skin.
Since peptides can be used orally and topically, it’s important to carefully assess the toxicity and safety of both naturally occurring and synthetically manufactured peptides.
We’re mainly concerned with peptides in skin care, so we conducted research on scientific studies that assess peptides. We found that chemical peptides show negligible toxicity, but natural peptides may have higher toxicity ratings.  Fortunately, synthetic peptides are mainly used in skin care products.
Peptides have been tested on animal subjects, cancer cells, and in various other scientific settings for applications beyond skin treatment (i.e. sports nutrition, autoimmune disease treatment, arthritis treatment, etc.). Because there are hundreds of peptides with perpetual combinations, more research may be needed to fully assess the safety of peptides in skin care.
Since the existing research shows that peptides are safe, peptides get The Good Face Project stamp of approval.
Peptides 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.
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. 
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.
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.
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.
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. 
When it comes to anti-aging ingredients that deserve more credit than they’re given, peptides are the top of the list. While peptides are gaining more traction in skin care, they’re still not given as much as attention as other ingredients, such as Retinol and Hyaluronic Acid. We don’t think you should replace your Hyaluronic Acid serums and Retinol creams with skin care containing peptides, but you should definitely give them a try if anti-aging is one of your major skin care concerns.
Since peptides can be used to address various anti-aging skin care concerns, including fine lines, wrinkles, sagging, and pigmentation, they make a great addition to anyone’s anti-aging skin care routine.
