Collagen Biostimulators are advanced treatments designed to enhance skin quality, firmness, texture, and overall luminosity. If you're looking for a way to rejuvenate your skin naturally, these treatments might be just what you need.
Both Sculptra and Radiesse encourage your skin to regenerate its own collagen. Each treatment uses a slightly different mechanism, making them suitable for various needs and preferences. These treatments don’t create bulk or artificial volume. Instead, they work gradually, strengthening the skin from within.
Understanding Collagen Biostimulators
To understand how Sculptra and Radiesse improve skin, it helps to know a little about fibroblasts. Fibroblasts are the cells in your skin responsible for producing collagen, elastin, and other components that give skin its firmness, smoothness, and resilience. Essentially, they’re the “builders” that maintain your skin’s structure and quality.
Both Sculptra and Radiesse work by stimulating fibroblasts, but they do so in slightly different ways:
Radiesse contains calcium hydroxyapatite (CaHA) microspheres. When injected, these microspheres act as a temporary scaffold, giving fibroblasts a framework to attach to. This physical presence activates the fibroblasts to produce collagen and elastin while also supporting healthy blood vessel formation. Over time, the CaHA is metabolised and replaced by your own new collagen.
Sculptra contains poly-L-lactic acid (PLLA) particles. When injected, these particles are recognised by fibroblasts as a bioactive stimulus, triggering them to ramp up collagen production. As the PLLA gradually dissolves, it leaves behind only your own regenerated collagen, improving skin firmness, texture, and radiance naturally.
In short: both treatments encourage your skin to rebuild and rejuvenate itself using your body’s own regenerative processes. They each use a unique mechanism to signal fibroblasts.
Radiesse: A Closer Look
Radiesse is made from CaHA (Calcium Hydroxylapatite), a biocompatible, lab-made material that’s very similar to the mineral naturally found in your bones and teeth. It also contains lidocaine for a numbing effect.
CaHA provides consistent collagen stimulation because its mechanism is less affected by individual variations in micronutrients, protein intake, or metabolic factors. The CaHA particles remain within the tissue and calcify, offering ongoing signalling that encourages collagen production over time. This stability often leads to uniform results across a wide range of patients.
Radiesse can be used in two ways:
Hyper-dilute for overall skin quality and collagen stimulation.
As a volumising filler in selected areas such as the cheeks and jawline, while still promoting collagen formation.
You can also combine hyper-dilute Radiesse for skin improvement with subtle structural support in the same session. This is done by using two syringes—one prepared hyper-dilute for collagen stimulation and one kept thicker for definition in areas like the cheeks or jawline.
Hyper-dilute Radiesse can be customised further with an NCTF boost to support tissue quality and reduce variability. It is also ideal for hand rejuvenation, improving skin quality, restoring volume, and creating a smooth, natural result.
Results can last 12-18 months, and sometimes even longer.
Sculptra: A Natural Approach
Sculptra uses poly-L-lactic acid (PLLA) to gradually stimulate your body’s own collagen over time. PLLA is essentially like crushed-up dissolvable sutures, which we hyper-dilute with sterile water and lidocaine for a numbing effect. The PLLA particles fully dissolve over a few months, leaving behind only your natural collagen. This makes it perfect for those who prefer that nothing remains in their skin long-term.
Sculptra’s collagen response can vary slightly between individuals because it is more influenced by:
Micronutrient levels
Protein availability
Immune response
Overall metabolic health
When these factors are optimal, Sculptra can produce beautifully natural, progressive, tissue-based improvement. Although its response can be influenced by these factors, this reflects the true regenerative nature of the treatment. It rebuilds your own collagen in a way that blends seamlessly with your natural tissue.
We use Sculptra for the face only, and results can last over 2 years.
Choosing Between Radiesse and Sculptra
Both treatments:
Stimulate natural collagen
Support angiogenesis and long-term skin health
Do not create bulk or a “filled” look
Deliver gradual, subtle, long-lasting improvement
Sculptra may suit you if you prefer:
A product that leaves nothing behind once dissolved
Results that rely solely on your own new collagen
A very natural, integrated improvement
A gradual refresh of facial skin quality
Results that can last over 2 years
Radiesse may suit you if you prefer:
Collagen stimulation that is less influenced by nutritional or metabolic factors
Treatment options for both face and hands
The ability to combine hyper-dilute skin improvement with structural support (cheeks/jawline) using two syringes in one session
A stable, consistent collagen-stimulating effect over time
Slightly more of an effect on angiogenesis
Results that can last 18 months
The Importance of Personalized Consultations
When considering these treatments, it’s essential to consult with a professional who understands your unique skin needs. A personalized consultation can help you explore the best options tailored to your skin type and aesthetic goals.
At NYAÁ Clinic, we prioritize a holistic and ethical approach to aesthetics. We believe that everyone deserves to feel confident and beautiful in their skin.

Conclusion
In conclusion, both Sculptra and Radiesse offer unique benefits for enhancing skin quality and promoting natural collagen production. Whether you choose Sculptra for its gradual, long-lasting results or Radiesse for its immediate effects and versatility, you’re taking a step towards healthier, more radiant skin.
Remember, the journey to beautiful skin is a personal one. Embrace the process, and let your natural beauty shine through!
