The intelligent skincare ingredients helping support smoother, firmer and healthier-looking skin.
Peptides have become some of the most talked-about ingredients in modern skincare—and with good reason.
These tiny but powerful compounds are valued for their ability to support the processes associated with healthy-looking skin. Depending on the particular peptide used, they can help improve the appearance of firmness, elasticity, fine lines and overall skin vitality.
But not all peptides are the same. Understanding how they work—and why a carefully formulated blend matters—can help you decide whether they deserve a place in your skincare routine.
What Are Peptides?
Peptides are short chains of amino acids.
Amino acids are often described as the building blocks of proteins. When joined together in different combinations, they form peptides and, eventually, larger proteins such as collagen and elastin.
These proteins play an important role in the skin’s structure, firmness and resilience. As we age, the natural processes responsible for maintaining them gradually become less efficient. This can contribute to visible changes such as:
- Fine lines and wrinkles
- Reduced firmness
- Loss of elasticity
- A thinner or less resilient appearance
- Slower-looking skin renewal
Peptide skincare is designed to help support the skin through these visible changes.
How Do Peptides Work in Skincare?
Peptides are sometimes described as “messengers” because certain peptides can help support communication within the skin.
Different peptides are designed to perform different functions. Depending on their structure, they may help support:
- Firmer and more elastic-looking skin
- The appearance of smoother skin
- Healthy skin renewal
- The skin’s natural barrier
- A more resilient complexion
- The softening of visible fine lines and wrinkles
This is why the word “peptide” alone does not tell you everything you need to know about a product. The specific peptide, its quality, the amount used and the complete formulation all influence how the finished product performs.

Are All Peptides the Same?
No. Peptides are a broad family of ingredients, and different types are used for different skincare goals.
Some peptides are chosen to help support the skin’s structural proteins. Others are used to promote a smoother-looking complexion, strengthen the skin barrier or support visible renewal.
A well-formulated peptide serum may combine more than one peptide technology so that the ingredients complement one another rather than relying on a single approach.
At Naturals Beauty, our Re-Gen Peptide Power Serum combines two advanced peptide technologies:
- Reneseed™ Peptide — an innovative bioengineered peptide designed to support skin renewal, vitality and a healthier-looking complexion.
- Copper Tripeptide-1 — a highly regarded skincare peptide used to support firmer, smoother and more resilient-looking skin.
These are combined with antioxidant-rich Malachite Extract and carefully selected hydrating ingredients to create a balanced daily serum.

What Can Peptides Do for the Skin?
When used consistently as part of a well-rounded skincare routine, peptides can help:
- Improve the appearance of skin firmness and elasticity
- Soften the visible appearance of fine lines and wrinkles
- Support smoother-looking skin
- Promote a healthier, more resilient complexion
- Support the skin’s natural renewal processes
- Complement hydrating and antioxidant skincare ingredients
Peptides are not an instant facelift, nor can a cosmetic product permanently reverse the natural ageing process. Their value lies in supporting the skin consistently over time.
As with most skincare actives, patience and regular use matter more than expecting an overnight transformation.
When Should You Start Using Peptides?
There is no single “correct” age to begin using peptide skincare. Read more in What Age Should You Start Using a Peptide Serum?
Peptides can be used preventatively when the first signs of ageing begin to appear, or introduced later to help address visible concerns such as loss of firmness, fine lines and reduced elasticity.
They may be especially helpful if your skin:
- Is beginning to show fine lines
- Feels less firm or resilient than it once did
- Looks tired, dull or less vibrant
- Needs additional support during periods of dryness
- Would benefit from a gentle, long-term approach to visible ageing
Because peptides are generally well tolerated, they can also be a good option for people who find stronger age-supporting actives difficult to use.
Can Peptides Be Used With Other Serums?
Yes. Peptides generally layer well with many popular skincare ingredients.
They can be used alongside Hyaluronic Acid, Niacinamide, Vitamin C, Squalane, botanical antioxidants, moisturisers and facial oils.
Our Re-Gen Peptide Power Serum has a lightweight, water-based texture that makes it easy to incorporate into an existing routine. Read How to Use a Peptide Serum in Your Skincare Routine for a step-by-step guide.
If you are layering several serums, apply them from the lightest texture to the richest. Allow each layer to absorb briefly before applying the next product.
How Do You Use a Peptide Serum?
Apply a few drops to clean skin after cleansing and toning.
Gently smooth the serum over the face, neck and décolletage, then follow with your moisturiser or facial oil. Peptide serum can be used in the morning, evening or both.
During the day, always complete your routine with a broad-spectrum sunscreen.
Consistency is key. Peptide skincare is best viewed as part of an ongoing routine that supports the skin gradually rather than as a once-off treatment.
💡 Myth vs Fact
Myth: All peptide serums are essentially the same.
Fact: There are many different types of peptides, each with its own structure and intended function. The specific peptide technologies, their concentrations and the overall formulation all matter.
Myth: The higher the peptide percentage, the better the serum.
Fact: Peptides are highly specialised ingredients and are often designed to perform at very specific concentrations. A bigger percentage does not automatically mean better results. The correct concentration and a well-balanced formulation are far more important.
Myth: Peptides only benefit mature skin.
Fact: Although peptides are particularly valuable for skin showing visible signs of ageing, they can also be used earlier to support skin resilience, hydration and long-term skin health.
💡 Did You Know?
A peptide’s name can look surprisingly complicated on an ingredient list.
For example, the Reneseed™ technology used in our Re-Gen Peptide Power Serum appears in the full INCI listing as Nicotiana Benthamiana Hexapeptide-40 sh-Polypeptide-76.
This is why reading only the front of a skincare label—or looking for the word “peptide”—does not always reveal the complete story behind a formulation.

Q: Why did you combine two different peptide technologies in the Re-Gen Peptide Power Serum?
A: Different peptides can offer complementary forms of skin support. Reneseed™ was selected to support skin renewal and vitality, while Copper Tripeptide-1 was chosen to support firmer, smoother and healthier-looking skin. Combining them with hydrating ingredients and antioxidant-rich Malachite Extract allowed us to create a more rounded formulation for visible signs of ageing.
