Peptide Benefits for Skin Guide

To help you better understand what peptides are and why you want them in your daily skincare routine, our Kate Somerville Skin Health Experts share the many benefits they provide.

What are Peptides?

Before we dive into the benefits of peptides for skin, let’s first get a better understanding of what this skin care ingredient is. Peptides are short-chain amino acids that act as the building blocks of protein. They help the body create proteins like collagen, elastin, and keratin – all of which are found in your skin. These proteins work diligently to improve your skin’s resiliency, texture, and strength. While there are many different peptides, research has shown that all peptides have a certain level of skin-restoring ability that can range from skin-soothing to firming [1].

Understanding the Power of Peptides in Skincare

By incorporating peptide products into your daily skincare routine and applying them to the skin’s surface, your body receives the message that it should make more of these skin-boosting proteins.

Now, if you’re wondering why not apply already-created proteins like collagen and keratin to your skin instead, there’s a simple answer. Peptides are fragmented portions of proteins, making them easy for the skin to absorb.

There are many ways you can incorporate peptides into your skincare regimen. Serums, moisturizers, and masks can all be formulated with peptides to deliver specific benefits to your skin.

Different Types of Peptides and How They Work

Not all peptides work the same way. Understanding the different types of peptides helps explain the true power of peptides in skin care products.

Signal Peptides

Signal peptides act as messengers that communicate with skin cells. These peptides stimulate collagen production by signaling cells to produce more collagen and elastin, which helps reduce the appearance of fine lines and wrinkles.

By supporting collagen production and boosting collagen production over time, signal peptides help keep your skin looking firmer, smoother, and more youthful. Signal peptides are especially beneficial in anti-aging products designed to target signs of aging.

Carrier Peptides

Carrier peptides help deliver essential trace minerals, such as copper, to the skin. These minerals for skin are important for tissue repair, collagen production, and overall skin health.

Copper peptides, a popular type of carrier peptides, support skin cells during the healing process and help improve skin tone, texture, and resilience.

Collagen Peptides and Enzyme-Inhibiting Peptides

Collagen peptides help support collagen and elastin by protecting existing proteins from breakdown. Enzyme-inhibiting peptides slow the degradation of collagen fibers, helping reduce the appearance of wrinkles and maintain a tauter, more resilient skin barrier.

Together, these peptides help make skin look firmer while supporting long-term anti-aging benefits.

Comprehensive Guide to the Skin Benefits of Peptides

When used in skincare, peptides act as a messenger, sending signals to our cells to start specific functions and direct them into carrying out these functions. Peptides can be divided into five main categories: carrier peptides, signal peptides, enzyme-inhibiting peptides, neurotransmitter-inhibiting peptides, and antimicrobial peptides [2]. These different peptides all have significant positive effects, contributing to more healthy-looking skin, including:

1. Combatting Wrinkles and Fine Lines with Peptides

As we age, our natural production of essential proteins such as collagen, elastin, and keratin decreases, leading to the formation of wrinkles and fine lines. Peptides encourage the skin to rebuild and repair itself, which provides your skin with fullness and preserves its youthful appearance. With anti-aging properties, peptides provide noticeable results in the fight against wrinkles and fine lines, much like the benefits of squalane in skincare. 

Our KateCeuticals™ Total Repair Cream is one peptide-infused product that, when used alone or with a serum morning and evening, leaves your skin nourished, refreshed, and firmer.

2. Hydration Boost: The Role of Peptides

Beyond combating signs of aging, peptides also play a crucial role in maintaining skin hydration. Loss in natural collagen production causes skin dehydration and transepidermal water loss. However, adding peptides to your skincare routine locks in moisture from your other skincare ingredients. Peptides act as moisture magnets, helping to retain essential moisture for a plumper and more radiant complexion when paired with vitamin C. 

Using a peptide-rich cream like our KateCeuticals Total Repair Cream doesn’t just feature hydrating ingredients like Hyaluronic Acid to replenish thirsty skin. Its advanced moisture complex helps keep skin more evenly balanced with humectants and conditioners while peptides work to diminish the visible depth and density of wrinkles while firming skin.

3. Peptides as a Remedy for Redness and Irritation

When applied topically, peptides signal the skin to prioritize the mending of its protective barrier. As a result, they aid in fortifying the skin’s natural defenses, reducing redness, and alleviating irritation. Introducing peptides to your regimen is a great way to calm your skin cells and even your skin tone, relieving your complexion of visible redness. This is especially good news for people looking for sensitive skin products who also want an anti-aging products in their skin care routine. 

Our Kate Somerville DeliKate™ Recovery Cream is a breakthrough clinical moisturizer with a peptide complex and ceramides that work together to relieve visible redness and irritation while restoring the skin barrier.

4. Restoring Firmness and Elasticity Through Peptides

When collagen fibers break down, peptides signal our skin to make more. As we age, collagen production naturally decreases, resulting in wrinkles, dehydration, and weakened skin elasticity. Think of it as the ultimate win-win. Peptides work to firm skin from the outside in and signal for your skin to firm it from the inside out. 

Our KateCeuticals™ Collection is a clinical age repair skin care system chock full of powerful peptides that takes a comprehensive approach to reversing the visible signs of aging. 

5. Refining Skin Texture with Peptide-Rich Formulas

Different types of peptides are versatile in their approach to enhancing skin texture. Their ability to boost collagen production not only increases skin firmness but also contributes to a smoother complexion for both dry skin and oily skin. Collagen, known for its role in maintaining skin’s structural integrity, plays a pivotal part in refining skin texture. Peptides are your one-way ticket to skin revitalization, as they improve your skin’s firmness, smoothness, and evenness. 

Transform your skin’s texture and replenish your pores with our ExfoliKate™ Collection, specifically designed for skincare targeting texture and pores. Experience a youthful glow and a visible difference in your skin’s smoothness, as our products work meticulously to enhance your skin’s overall appearance and health.
