Collagen-Stimulating Fillers
If you’re looking for facial rejuvenation that goes beyond a quick fix, collagen-stimulating fillers can restore volume, refine contours, and improve skin firmness by encouraging your body to rebuild collagen over time. At our Santa Fe clinic, we offer three leading options—Radiesse®, Bellafill®, and Sculptra®—to treat volume loss, deeper lines, and acne scarring with natural-looking results.
What Are Collagen-Stimulating Fillers?
Unlike traditional fillers that primarily “fill” with gel, collagen-stimulating injectables work in two ways:
-
Immediate improvement (in select products) to lift and contour
-
Gradual collagen production to strengthen skin structure and support longer-lasting results
These treatments are ideal for patients who want subtle, natural enhancement, improved skin quality, and longer-lasting correction compared with many hyaluronic acid (HA) fillers.
Radiesse® (CaHA)
What is Radiesse?
Radiesse is an FDA-approved dermal filler that provides immediate volume and contour, while also stimulating natural collagen production. It’s a popular choice for facial sculpting and improving skin firmness over time.
What it’s made of
-
Calcium hydroxylapatite (CaHA) microspheres suspended in a gel carrier
Best for:
-
Cheeks and midface volume
-
Jawline definition and lower-face contour
-
Nasolabial folds and marionette lines
-
Chin enhancement (contour support)
-
Hands (one of Radiesse’s signature treatment areas)
How long it last?
Many patients see results lasting about 12–18 months (sometimes longer depending on treatment area and metabolism).
Downtime & side effects
Temporary swelling, bruising, or tenderness may occur. As with any injectable, technique and placement matter—choosing an experienced injector is key.
Bellafill® (PMMA + Collagen)
What is Bellafill?
Bellafill is a long-lasting, FDA-approved filler that acts as both a volume enhancer and a collagen biostimulator. It is especially known for treating acne scars and deeper facial lines with results that may last up to 5 years or longer in some patients.
What it’s made of?
-
PMMA microspheres (20%): provide long-term structural support and a scaffold for collagen
-
Bovine collagen gel (80%): provides immediate lift while your body builds its own collagen
Best for:
-
Nasolabial folds (smile lines)
-
Acne scars
-
Marionette lines
-
Cheeks and temples (provider-dependent/off-label)
Important considerations
-
Skin testing is required due to bovine collagen allergy risk in a small number of patients
-
Not reversible like HA fillers, so precise placement is essential
-
Typically not recommended for lips or very superficial fine lines
Downtime & side effects
Bruising, swelling, or redness are possible. Small lumps/nodules are rare but can occur.
Sculptra® (PLLA)
What is Sculptra?
Sculptra is a collagen-stimulating injectable designed to restore facial volume gradually for a natural, refreshed look. It works differently than traditional fillers—results develop over time as collagen rebuilds.
What it’s made of?
-
Poly-L-lactic acid (PLLA), a biocompatible collagen stimulator
Best for:
-
Global facial volume restoration
-
Cheeks, temples, and midface hollowness
-
Softening lines caused by volume loss
-
Improving overall facial contour and skin support
How long it lasts?
Results commonly last 2 years or more, especially when completed as a planned series.
Treatment plan
Sculptra is typically performed in a series of sessions spaced several weeks apart for optimal collagen-building.
Aftercare
Your provider may recommend massage after treatment and standard post-injection care (avoid heavy heat/exercise for a short period, wear sunscreen, etc.).
Renuva®
What is Renuva?
Renuva is an FDA-regulated injectable treatment designed to restore volume loss by helping your body naturally regenerate fat tissue over time. Unlike traditional fillers, Renuva works as a scaffold that supports your body’s own fat growth for gradual, natural-looking results.
What it’s made of
Processed donor adipose (fat) matrix containing growth factors, collagen, and proteins — with no living fat cells
Best for:
-
Restoring volume in areas with fat loss
-
Temples and hollow cheeks
-
Jawline softening and contour refinement
-
Hip dips and small body contour irregularities
-
Improving the appearance of scars or depressions
-
Hands (for a smoother, fuller appearance)
How long does it last?
Results develop gradually over several weeks to months as your body builds its own fat tissue. Many patients enjoy long-lasting results that can remain for years, depending on the treatment area and individual metabolism.
Downtime & side effects
Temporary swelling, bruising, redness, or tenderness at the injection site may occur. Because Renuva stimulates your body’s natural regenerative process, results appear progressively rather than instantly. Proper placement and technique are essential, so choosing an experienced injector is important.
Which Filler Is Right for You?
Radiesse
Best if you want immediate lift + collagen stimulation, especially for cheeks, jawline, and hands.
Bellafill
Best for acne scars and patients who want a very long-lasting option, and who are comfortable with a product that isn’t reversible.
Sculptra
Best for gradual, natural-looking volume restoration and collagen rebuilding across larger areas.
Renuva®
Best for patients looking to restore volume naturally using their body’s own fat regeneration process. Ideal for subtle, long-term enhancement in areas with fat loss, including the face, hands, hips, and contour irregularities.
