All biostimulators share the same core goal: stimulating your body’s natural collagen production. But they achieve this using different materials:
The active ingredient in Sculptra
The active ingredient in Radiesse
The active ingredient in Ellanse
All three are biocompatible and biodegradable, meaning they’re safely absorbed by your body over time.
Sculptra is one of the most well-established bio-stimulators worldwide, with over two decades of clinical use.
Sculptra is particularly popular for patients who want subtle, progressive improvement.
Results develop gradually and improve over time, creating natural rejuvenation that lasts.
Radiesse is unique because it offers both immediate and long-term benefits.
Hyperdilute Radiesse has become increasingly popular for treating larger areas like the neck, decolletage, and hands.
Results develop gradually and improve over time, creating natural rejuvenation that lasts.

None of these biostimulators are reversible in the way hyaluronic acid fillers can be dissolved. This is why choosing an experienced physician is particularly important.

Biostimulators are suitable for a wide range of patients, but they’re particularly beneficial for those who are experiencing:
They tend to work well for individuals in their 30s to 60s, though the approach may vary depending on your starting point. A consultation with a qualified aesthetic physician is the best way to determine if biostimulators are right for you.
Biostimulator treatments are typically quick, taking around 30 to 45 minutes. A topical numbing cream is usually applied beforehand to ensure comfort.
After treatment, you may experience mild swelling, redness, or tenderness at the injection sites — this is normal and usually resolves within a few days. Your doctor may recommend gentle massage of the treated areas to ensure even distribution of the product.
Because results develop gradually, patience is key. Most treatment plans involve 2 to 3 sessions spaced a few weeks apart, with the full effect becoming visible over the following months.
There’s no single “right” age — it depends on your skin condition, lifestyle, and goals. However, here’s a general guide:
Early biostimulator treatments can help maintain your collagen levels before significant loss occurs.
Biostimulators can be especially effective at this stage because your body still has good capacity to respond to collagen stimulation.
Biostimulators can still deliver meaningful improvements, often combined with other treatments for a more comprehensive approach.
The best time to start is before changes become pronounced. Collagen takes time to rebuild, so early intervention allows for more gradual, natural, and preventative ageing management.
Yes — many patients benefit from combining treatments. Our doctors design protocols based on your skin concerns and goals.
Most treatments use topical anesthetic for comfort. Sensations vary by modality — mild warmth, tingling, or pressure are common.
Initial improvements appear within 1–4 weeks; collagen continues to rebuild for 3–6 months after treatment.
Depends on the treatment. Maintenance sessions every 6–12 months are typical for long-term results.
Temporary redness, mild swelling, or warmth are common and resolve quickly. Our doctors discuss all considerations before treatment.
Each biostimulator has its strengths, and there’s no single “best” product that works for everyone. What matters most is understanding your own skin’s needs, having realistic expectations, and working with a doctor who can guide you toward the right treatment plan.
