Let’s talk about something we all want: skin that looks healthy, smooth, and firm. Whether you are young or old, you want your skin to look amazing. Believe it or not, but peptides can give your skin a fresher, smoother, and younger appearance.
Now, if you’ve been dabbling in skincare for a while, you’ve probably come across the word peptides. Maybe even collagen peptides. But what exactly are they? What do peptides do for skin? And more importantly, are they worth the hype that is currently fueling social media trends and fads centering around peptides?
If you’ve been eyeing products with promises of plumper, more youthful-looking skin, peptides are for you. In this article, we’re going to break down what peptides are, how they help with collagen production, and why they’re the quiet heroes behind some of Eight Saints’ most beloved products.
So...What Are Peptides, Anyway?
Peptides are short chains of amino acids. That’s it. That’s the definition. But don’t let their simplicity fool you—amino acids are the building blocks of proteins, and proteins are what keep your skin strong, elastic, and oh-so-smooth.
One of the most important proteins in your skin? Collagen.
When you apply peptides topically (like in a peptide moisturizer or serum), your skin sees them as little messengers. These messengers basically say, “Hey! We need more collagen over here!” and your skin gets to work.
Collagen Peptides and Skin—The Connection
Here’s the thing: as we age, our collagen production takes a nosedive. You might start to notice fine lines, sagging, and a general loss of plumpness. It’s not just your imagination—your skin literally has less of the stuff that keeps it looking youthful.
That’s where collagen peptides come in. These specific peptides either directly contribute to collagen formation or signal the skin to produce more of it. So while you can’t technically slather collagen itself on your face and expect it to absorb (it’s a large molecule), you can use peptides for skin that tell your body, “More collagen, please.”
What Do Peptides Do for Skin?
Let’s go a little deeper. Besides promoting collagen, peptides also:
- Improve skin texture and tone
- Reduce inflammation (yes, they can be anti-inflammatory!)
- Help reinforce your skin barrier (goodbye, sensitivity!)
- Minimize the appearance of wrinkles and fine lines
And while they’re working their magic, they’re usually pretty gentle on the skin. Unlike some harsher anti-aging ingredients (looking at you, retinoids), peptides rarely cause irritation. They’re kind of the chill friend in your skincare routine—quiet, supportive, but wildly effective.
The Best Peptides for Skin: Not All Are Created Equal
There are lots of peptides out there, and some are more effective than others. Signal peptides are the ones that prompt collagen production. Carrier peptides deliver trace elements (like copper) to the skin, and enzyme-inhibitor peptides help prevent collagen breakdown.
Here’s the bottom line: a product that uses well-researched, clinically-backed peptides can really make a difference. And surprise, surprise—both of these next products from Eight Saints are packed with them.
Up the Anti Anti-Aging Cream
This little jar of Up the Anti Anti-Aging Cream is doing the most. Not only does it contain powerful peptides, but it also pairs them with hyaluronic acid (for deep hydration), squalane (for barrier repair), and vitamin C (for brightening and antioxidant support). So you’re getting a full cocktail of ingredients that complement each other beautifully.
The peptides in Up the Anti are there to boost collagen, firm up skin, and reduce the look of those pesky lines that tend to show up when you least expect them.
Apply it at night, and let it work while you sleep. You’ll wake up to skin that feels a little bouncier, a little more hydrated, and a lot more alive.
All In Eye Cream
The skin around your eyes is thinner and more delicate, which means it shows signs of aging faster than the rest of your face. That’s why a peptide-rich eye cream is a non-negotiable. All in Eye Cream from Eight Saints is an excellent peptide-rich choice.
All In Eye Cream delivers peptides right where they’re needed—under your eyes, in your crow’s feet, and anywhere puffiness or fine lines are creeping in. Bonus: it also includes hyaluronic acid and caffeine to de-puff and hydrate like a dream. It’s lightweight, absorbs fast, and makes you look so much more awake.
Amino Acids: Why You Should Care
Let’s rewind for a second. Remember how we said peptides are made of amino acids? Well, amino acids on their own are also fantastic for skin. They help maintain hydration, strengthen the skin barrier, and support healing. When your skincare includes both amino acids and peptides, it’s like giving your skin the tools and the instructions for a glow-up.
The Role of Hyaluronic Acid (AKA Your Skin’s BFF)
You’ve seen this one everywhere, right? That’s because hyaluronic acid is a hydration superstar. It holds up to 1000 times its weight in water. But here’s what makes it especially great in peptide products:
When peptides help build collagen, your skin starts to get firmer. But for that collagen to really do its job, your skin also needs moisture. Hyaluronic acid steps in to plump up the skin and make everything look smoother and softer.
Together, peptides and hyaluronic acid are a skin-repairing dream team.
Peptide Moisturizer: Why It’s Worth the Splurge
If you’ve been wondering whether peptide moisturizers are actually worth the money, here’s the honest truth: when they’re well-formulated (like Up the Anti), absolutely.
A good peptide moisturizer doesn’t just sit on your skin. It actively works to improve its texture, bounce, and firmness over time. And because peptides are often gentle, they play nicely with other ingredients like vitamin C, hyaluronic acid, and niacinamide.
If you’re building an anti-aging skincare routine or just want to start treating your skin a little better, adding a peptide moisturizer is a smart move.
Collagen for Skin: What to Expect
Let’s manage expectations real quick: collagen production doesn’t happen overnight. But stick with your routine, and you will notice your skin looking smoother and more resilient over time.
Here are a few collagen benefits for skin that you might see with consistent peptide use:
- Fewer visible wrinkles
- Improved elasticity
- A more even skin tone
- Smoother texture
- More hydrated, “bouncy” skin
It’s subtle at first, but give it a few weeks, and you’ll understand why peptides are such a skincare favorite.
Peptides + Skincare = A Routine That Works
One of the best parts about peptides is how well they fit into just about any skincare routine. Sensitive skin? No problem. Already using retinol? Peptides can support your skin barrier while retinol does its thing.
If you’re not sure where to start, try using All In Eye Cream in the morning and Up the Anti Anti-Aging Cream at night. That’s it. Easy. You’ll be giving your skin exactly what it needs to start rebuilding collagen, without a 10-step routine.
Peptides Are Anti-Inflammatory, Too
One more thing to love: peptides have anti-inflammatory properties, meaning they help calm redness and soothe irritation. This is especially helpful if your skin’s been feeling stressed, inflamed, or just a little out of balance.
By promoting healing and reducing inflammation, peptides don’t just make your skin look better—they help it feel better, too.
Are Peptides the Secret to Great Skin?
Honestly? They just might be.
If you’re serious about skincare—or even just dipping your toes in—it’s worth understanding what peptides for skin can do. They support collagen production, improve texture, reduce inflammation, and help your skin bounce back.
And when paired with powerhouse ingredients like amino acids and hyaluronic acid, you’ve got a recipe for skin that looks refreshed, hydrated, and genuinely healthy.

FAQs About Peptides and Collagen in Skincare
What are peptides for skin, and how do they work?
Peptides are short chains of amino acids that act as messengers in the skin. They signal your skin to produce more collagen and elastin, two proteins responsible for keeping your skin firm, smooth, and youthful. When used in skincare, peptides help repair, strengthen, and improve overall skin texture over time.
What do peptides do for skin that other ingredients don’t?
Peptides are unique because they support your skin’s natural processes. Instead of just hydrating or exfoliating, they help stimulate collagen production, strengthen the skin barrier, reduce inflammation, and improve firmness. Plus, they’re gentle and can be combined with most other ingredients like hyaluronic acid or vitamin C.
How long does it take to see results from collagen peptides in skincare?
Results vary by skin type, but most people begin to notice subtle changes within 3–4 weeks of consistent use. Long-term use (around 8–12 weeks) often leads to firmer, smoother, and more resilient skin, especially when paired with other active ingredients.
Can I use peptides with other skincare products like retinol or acids?
Yes! Peptides are generally very skin-friendly and can be used alongside retinol, AHAs, BHAs, hyaluronic acid, and vitamin C. In fact, they can help soothe and strengthen the skin barrier, making them perfect partners for stronger actives.
What’s the best way to apply a peptide moisturizer or eye cream?
Apply peptide creams on clean, slightly damp skin to help lock in moisture. For the face, use a small amount of your peptide moisturizer (like Up the Anti) and gently massage it in using upward strokes. For eye creams like All In, tap a small amount around the eye area using your ring finger for the lightest touch.
Are peptides safe for sensitive or acne-prone skin?
Absolutely. Most peptides are non-irritating and even have anti-inflammatory properties, which makes them great for calming redness and promoting healing. As always, patch test if you’re trying a new product, but peptides are generally considered safe for all skin types.
