What Are Biostimulators? Understanding Collagen-Stimulating Injectables

Did you know that by the time you hit 30, your body starts producing about 1% less collagen each year? Yeah, just 1%—but over time, that adds up. 

By 40, you’ve already lost around 10% of your skin’s collagen. Fast-forward a decade or two and suddenly your skin doesn’t bounce back like it used to. Wrinkles settle in. Volume disappears. That glow? Gone. The kicker? It’s totally normal. But it doesn’t have to be permanent.

Welcome to the world of biostimulators—the low-key, science-backed way to kick your skin into gear and get that collagen engine running again. 

At Coastal Aesthetics Premier Med Spa in York, ME, we proudly offer Sculptra® and Radiesse®, two of the most effective collagen-stimulating dermal fillers on the market. 

These aren’t your average fillers—they help rebuild what time takes away.

Collagen: The Glue Holding It All Together

Collagen is the most abundant protein in your body. It’s basically the scaffolding that keeps your skin firm, plump, and youthful. Think of it like the mattress springs underneath a luxury pillow-top. When those springs are tight, the bed looks great. When they wear out, everything sags.

With aging, sun exposure, lifestyle factors (like smoking and poor diet), and even stress, collagen starts breaking down faster than your body can replace it. That leads to:

• Sagging skin
• Fine lines and deep wrinkles
• Hollowed cheeks
• Loss of jawline definition
• Thinner, crepey texture

The problem? Topical creams and serums can only go so far. You need something that works below the surface.

Meet the Collagen Comeback Crew: Biostimulators

Biostimulators are injectables that stimulate your body’s natural ability to produce collagen. They don’t just fill in lines—they lay the foundation for longer-term skin rejuvenation.

Biostimulator vs. Filler: What’s the Difference?

• Fillers: Add instant volume. Typically made with hyaluronic acid. Great for immediate results but gradually dissolve over months.
• Biostimulators: Gradually restore volume by prompting your body to create its own collagen. Results appear over time and tend to last longer.

At Coastal Aesthetics, we offer two industry-leading biostimulators: Sculptra® and Radiesse®.

The Power of Sculptra®: Rebuild From the Inside Out

Sculptra® uses poly-L-lactic acid (PLLA), a biodegradable compound that jumpstarts collagen production in the deeper layers of your skin. It’s the go-to choice for restoring volume to areas like the cheeks, temples, and jawline—places where aging really makes its mark.

Why People Love It:

• Gradual and natural-looking results
• Long-lasting effects (up to 2 years!)
• Excellent for deep facial volume loss and skin tightening

Sculptra works in a series of treatments spaced weeks apart. 

You’ll notice improvement within a few months, and the results continue to improve over time as your body builds fresh collagen.

Radiesse®: Instant Lift, Long-Term Collagen

Radiesse® is made with calcium hydroxylapatite (CaHA), a mineral-like compound found naturally in bones. What sets Radiesse apart is its dual-action: it gives immediate volume AND stimulates collagen production over time.

Why It’s a Fan Favorite:

• Instant improvement with visible lift
• Long-term collagen stimulation
• Ideal for hands, lower face, jawline, and nasolabial folds
• Smooths AND strengthens skin structure

At Coastal Aesthetics, Radiesse is often used for facial contouring and rejuvenating aging hands—two of the most common areas where collagen loss is obvious.

How the Magic Happens: Behind the Needle

Here’s what to expect during a biostimulator treatment at Coastal Aesthetics:

1. Consultation & Custom Plan

We assess your skin, talk about your goals, and develop a personalized treatment plan. No cookie-cutter treatments here.

2. Injection Day

Using fine needles or cannulas, we inject the biostimulator into strategic areas. The process takes about 30-60 minutes. Most patients find it very tolerable.

3. Aftercare & Healing

You might see mild swelling, bruising, or tenderness for a few days. These are normal and usually resolve quickly. We’ll walk you through how to care for your skin and what to expect.

4. Wait for the Glow-Up

Biostimulators aren’t instant-gratification treatments—they’re long-term investments in your skin’s health. Full results typically show up in 2–3 months.

Who’s a Good Candidate?

Biostimulators are great for:

• Men and women with mild to moderate volume loss
• Those looking for gradual, natural improvement
• People who want longer-lasting results without frequent touch-ups

They’re not ideal for:

• Pregnant or breastfeeding women
• People with autoimmune disorders (depending on condition)
• Those wanting instant results only

Loose Skin? Thinning Cheeks? Hollow Temples? Here’s Why You Should Care

As collagen declines, everything starts to shift. The mid-face loses volume and pulls downward. The under-eye area starts to hollow. Your jawline softens, and the neck can start to sag. Biostimulators target all these areas by encouraging your skin to act younger and healthier.

You’re not just treating symptoms—you’re addressing the root cause: collagen depletion.

Struggling with loose skin? We can help.
