Growth Factors vs. Peptides: Meet the CEOs & Team Leaders of Your Skin

When I First Heard of Growth Factors & Peptides…

When I first started in aesthetics back in 2001, I remember sitting in training and hearing about growth factors and peptides for the very first time. Up until then, I was just like so many of my clients—my skincare routine was whatever Sephora was pushing that season. I had never even heard of these ingredients, but my mentor told me they were crucial to skin health.

Here’s the thing: I’ve never been one to just take someone’s word for it. I needed to understand why. How could I confidently recommend something to a client if I didn’t truly know how it worked?

Fast forward to today, and growth factors and peptides are everywhere—serums, creams, TikTok trends, you name it. It’s overwhelming to know which product is actually worth your investment. That’s why I want to break down how these powerful ingredients work, who they benefit, and which products in our spa actually deliver the results they promise.

What Are Growth Factors and Peptides—Really?

Let’s make this simple.

✨ Growth Factors

Think of growth factors as the CEO of your skin. They’re the big decision makers, sending out the most important memos: “Make more collagen,” “repair that damage,” “bring back some firmness.” When we’re younger, our skin’s CEO is busy and efficient. But as we age, the CEO slows down—and that’s when lines, wrinkles, and sagging start to show. Using skincare with growth factors is like hiring an energetic new CEO who reminds your skin how to act young again.

✨ Peptides

If growth factors are the CEO, peptides are the team leaders. They don’t run the whole company, but they make sure the specific jobs get done. One might be in charge of boosting collagen, another is calming redness, while another focuses on keeping skin hydrated and strong. Peptides keep the day-to-day operations running smoothly so your skin stays healthy, firm, and glowing.

Meet Our Lineup: Growth Factor & Peptide Powerhouses

Now that you know growth factors are the CEOs and peptides are the team leaders, let’s talk about the products we’ve carefully chosen at Subtle T Aesthetics. These aren’t random serums off a Sephora shelf—these are medical-grade, results-driven formulas that actually deliver (and that I personally trust on my own skin).

Here are the six we love most, how they fit into your routine, and who they’re perfect for:

Neocutis Favorites

✨ Bioserum Firm

Our most powerful anti-aging serum, packed with growth factors + peptides.

• How to use: Apply morning and night after cleansing, before moisturizer.

• Who needs it: Anyone seeing sagging, deeper wrinkles, or wanting an overall “reset” in firmness and glow.

Think of this as your skin’s CEO—bringing back structure, lift, and vitality. Because your skin deserves a boss who actually shows up to work.

✨ Lumière Firm Eye Crème

Bright, rested eyes in a jar. Growth factors + peptides designed specifically for delicate under-eyes.

• How to use: Tap a pea-sized amount under the eyes morning and night.

Like bottling up eight hours of sleep—minus the bedtime story.

✨ Aftercare

The calming hero. A peptide-rich cream that soothes and protects stressed skin.

• How to use: Apply after treatments or whenever your skin feels sensitive. Can layer under SPF.

• Who needs it: Post-procedure clients, sensitive skin, or anyone craving comfort and repair.

Think of it as a soft, healing hug for your skin—minus the awkward squeeze.
