HA Fillers vs. Biostimulatory Fillers: What’s the Difference?
At RevitalyzeMD, we believe great outcomes start with education. When it comes to facial rejuvenation without surgery, dermal fillers are among the most powerful tools in aesthetic medicine—but not all fillers are the same.
There are two main types:
- HA fillers offer instant volume and hydration—ideal for lips, under-eyes, and soft contouring.
- Biostimulatory fillers like Radiesse® and Sculptra® stimulate collagen for long-term lift and skin support.
Your perfect filler depends on your goals—and often, the best results come from combining both.
Hyaluronic Acid (HA) Fillers
Best for Immediate Volume + Precision Refinement
HA fillers are composed of a naturally occurring sugar molecule that binds to water, making them the go-to for soft, smooth volume and hydration. Whether you’re enhancing lips, lifting cheeks, or softening fine lines, HA fillers offer a highly customizable solution.
How They Work
HA attracts and retains moisture, instantly plumping the skin and smoothing wrinkles.
Key Benefits
- Immediate, natural-looking results
- Easily reversible with hyaluronidase
- Ideal for delicate areas (lips, under-eyes)
- Customizable for contouring and balance
- Minimal downtime
Longevity
Typically lasts 6–18 months, depending on the formula and location.
Best For
Patients seeking subtle, precise enhancements with minimal recovery. Perfect for first-timers or anyone wanting a quick refresh.
How They Work
These fillers trigger fibroblasts to generate new collagen over time, restoring elasticity and volume from within.
Key Benefits
- Long-lasting outcomes (1–2+ years)
- Improves skin texture, firmness, and quality
- Ideal for deeper volume loss and skin laxity
- Builds over time for subtle rejuvenation
Best For
Patients looking for long-term facial support and collagen regeneration—often in mid-face, temples, jawline, or buttocks.
Spotlight on Radiesse®: Dr. Durst’s Go-To Collagen-Stimulating Filler
Radiesse delivers dual benefits—immediate lift + long-term collagen boost.
Formulated with calcium hydroxylapatite (CaHA) microspheres, Radiesse acts fast to restore volume and continues working beneath the skin’s surface by stimulating collagen production.
What Makes Radiesse Different?
- Immediate Results – visible lift right after treatment
- Long-Term Firming – enhanced elasticity and skin density over time
- Minimal Aftercare – no post-treatment massaging required
- Low Risk of Nodules – safer profile when administered by skilled injectors
Unique Uses
- Hyperdiluted Radiesse for crepey skin on neck, décolletage, or arms
- Standard Radiesse for cheeks, jawline, nasolabial folds, and even hands
- Body Rejuvenation – including buttocks and thighs for a subtle, natural lift
Dr. Debra Durst is known for her ability to blend science with artistry, and Radiesse is one of her favorites for a reason. It’s not just about filling—it’s about restoring integrity to your skin.
