If you're looking to improve skin firmness and smooth the appearance of fine lines and wrinkles, peptides may be just what your skin care routine needs. These short chains of amino acids act as biological messengers, signaling the skin to support collagen production and maintain a firmer, more youthful-looking complexion. Consider this your cheat sheet on the benefits of peptides, why they work and how they reduce the look of wrinkles.
Peptides are short chains of amino acids that act as the fundamental building blocks of essential skin proteins like collagen, elastin and keratin. They signal skin cells to support repair processes, improve the appearance of firmness and help maintain a strong moisture barrier. Because these proteins are crucial for healthy skin, the peptides that help support their production may also benefit skin health.
The body naturally produces endogenous peptides, while those used in topical skin care are considered exogenous. Depending on the type of peptide and formulation, topical peptides can serve different functions, from supporting the look of firmness to helping improve the appearance of expression lines.
Collagen is the main structural protein that provides support and elasticity to the skin. Often described as the “brick and mortar” of our skin, collagen also acts as a building block for bones, joints, teeth, muscles and connective tissues. Along with elastin, collagen is a protein that keeps the skin firm and stretchy. As we age, changes in these structural proteins can contribute to skin that looks thinner and less resilient, making fine lines and wrinkles more noticeable.
Lifestyle factors such as sun exposure and smoking can also contribute to collagen breakdown. The dermis also thins over time and holds on to less oil and moisture, causing wrinkles to appear on the skin.
To understand how peptides can help fight the look of wrinkles, it helps to know what happens to collagen as we age. The skin is made up of three layers: the epidermis, the dermis and the hypodermis. Within the dermis, collagen helps support the skin and maintain its firmness and elasticity.
So, where do peptides fit in? Peptides are short chains of amino acids that can play different roles in skin care, including acting as messenger molecules. Certain peptides can “signal” skin cells to support processes involved in collagen and elastin production. By incorporating peptide-infused skin care products into your routine, you may help support firmer, smoother-looking skin and reduce the appearance of fine lines and wrinkles over time.
When collagen breaks down, it forms peptides that signal the skin to produce new collagen. By applying additional signaling peptides through skin care products, we actually ‘tell’ the skin cells to make more collagen. By supporting collagen production, peptides can help promote firmer, more supple-looking skin.
There are hundreds of varieties of peptides, but when it comes to skin care products, a couple of key players stand out. Eminence Organics Lead Skin Care Trainer Natalie Pergar says there are two she considers to be the most effective — signaling peptides and neuropeptides. Signaling peptides support the body's natural processes involved in collagen production, helping minimize the appearance of fine lines and wrinkles. Neuropeptides, on the other hand, work on the muscular level to block the transmission of signals from the nerves to the facial muscles.
As Natalie describes: “One important difference between peptides and other beauty ingredients is that peptides work harmoniously with the body’s own natural processes. Other ingredients may work to benefit the skin but cannot trigger a response in the body — for example, vitamin C will provide antioxidants, but the body is incapable of producing vitamin C itself. ”
Our Advanced Care Collection uses peptides and botanical lipids to support the appearance of resilience and recovery. The peptides in this collection, specifically copper tripeptides and tetrapeptides, are designed to improve the look of firmness and elasticity.
The Copper Tripeptide Serum and the Tetrapeptide Lifting Gel increase the appearance of strength and elasticity, while the Ceramide Repair Balm utilizes a Ceramide Complex and allantoin to support the look of the skin’s natural moisture barrier.
Our Copper Tripeptide Serum features a 3% copper tripeptide to act as a recovery multitasker. It helps improve the look of collagen-depleted areas and is clinically shown to reduce the appearance of redness by 97%*, making it ideal for use after professional services or after using strong actives at home.
The Tetrapeptide Lifting Gel is formulated with advanced tetrapeptides in a weightless, oil-free gel. This helps the skin feel more contoured and firm, with 94% of users agreeing their skin looked more lifted after 28 days.**
You’ll also love the Ceramide Repair Balm, which acts as a protective shield for your skin barrier. It’s clinically proven to improve the appearance of dry, flaky skin in as little as 14 days by replenishing essential hydration***.
Another way to experience the benefits of peptides is with our Marine Flower Peptide Collection, which uses plant-based peptides as well as marine flower technology. The peptides in this collection are naturally derived from sacha inchi and rice protein, designed to take advantage of our natural collagen-building processes to increase the look of firmness and elasticity in our skin.
The Marine Flower Peptide Serum and the Marine Flower Peptide Eye Cream also contain a Smart Collagen+ Complex, a skin care ingredient formulated with cruelty-free collagen, natural plant peptides and sustainably sourced freshwater and saltwater algae. The Smart Collagen+ Complex and potent plant peptides give your skin the look of increased strength, elasticity and suppleness, while advanced algae extracts boost the appearance of firmness and provide long-lasting hydration, both of which minimize the natural formation of wrinkles.
Are peptides suitable for sensitive skin? Peptides are generally well tolerated by most skin types, including sensitive skin. However, other ingredients in a peptide product may cause irritation, so it's best to introduce new products gradually and patch-test before use.
How long does it take to see results from peptide skin care? Results vary depending on the peptide formulation and your skin's needs. With consistent use, you may notice improvements in hydration and skin texture within a few weeks, while visible changes in firmness may take longer.
Do peptides help with skin hydration? Some peptide formulations can help support the skin barrier, which plays an important role in maintaining hydration. For added moisture, look for peptide products formulated with hydrating ingredients such as hyaluronic acid, glycerin or ceramides.
Can you use peptides with retinol? Yes, peptides can generally be used alongside retinol. While retinol helps support skin renewal, peptides can complement your routine by helping improve the appearance of firmness and smoothness.
Are plant-based peptides as effective as synthetic peptides? Both plant-derived and synthetic peptides can offer skin care benefits, depending on their structure, formulation and intended function. The source alone doesn't determine effectiveness; the specific peptide and how it's formulated in a product also matter.
With this crash course, we’re sure you’re primed to expand your collection of peptide skin care products. Visit your nearest Eminence Organics Spa Partner to find out more about adding peptides to your skin care routine.
