Radiesse is an FDA-approved calcium hydroxyapatite (CaHA) biostimulator engineered to restore skin quality, elasticity, and firmness by triggering the body’s own collagen production. It is not a volumizing filler but a regenerative treatment. At our clinic in Nişantaşı, Istanbul, we specialize in “Hyperdilute Radiesse” protocols to tighten loose skin on the face, neck, and body, offering a premium experience for our international patients.
What Is Radiesse?
Radiesse is a powerful injectable biostimulator made of Calcium Hydroxyapatite (CaHA) microspheres. Unlike traditional Hyaluronic Acid fillers that simply add volume, Radiesse works biologically to rejuvenate the skin’s architecture.
Key Benefits:
● Collagen Stimulation: Supports the skin’s natural regeneration process by promoting fibroblast-mediated Type I and Type III collagen production over time.
● Skin Tightening: Improves dermal thickness and smooths crepey texture.
● Non-Volumizing: Ideal for patients who want to avoid the “puffy” or “over-filled” look.
Which Treatment Is Right for You?
To help you decide, here is how Radiesse compares to other popular injectable treatments available in our clinic:
1. Radiesse (CaHA)
● Primary Goal: Skin tightening, structural improvement, and long-term quality.
● Mechanism: Biostimulation (Active collagen production).
● Longevity: 12–18 Months.

● Volume Effect: None / Minimal (when used in Hyperdilute form).
2. Dermal Fillers (Hyaluronic Acid)
● Primary Goal: Restoring lost volume and shaping contours (e.g., Lips, Cheeks).
● Mechanism: Filling hollow spaces physically.
● Longevity: 6–12 Months.
● Volume Effect: High / Immediate volume.
3. Mesotherapy / Skin Boosters
● Primary Goal: Deep hydration and surface glow.
● Mechanism: Moisture retention.
● Longevity: 3–6 Months.
● Volume Effect: None.
Why Does Skin Age? How Does CaHA Help?
As we age, fibroblast activity slows down. This leads to a weakened Extracellular Matrix (ECM),
resulting in sagging and crepey skin. When Radiesse is injected, the CaHA microspheres act as a scaffold. They physically stimulate
fibroblasts to “wake up” and start producing new collagen. Histological studies confirm that this creates a denser, younger-looking dermis.
What Is Hyperdilute Radiesse?
Hyperdilute Technique:
The hyperdilute technique is designed to prioritize skin quality improvement by enhancing tissue diffusion rather than volumization. This transforms it from a thick filler into a spreadable, skin-rejuvenating wash.
● Targeted Tightening: Perfect for larger areas like the neck or décolletage.
● Natural Results: No risk of lumps or unnatural volume changes.
● Versatility: Can be used on the body as well as the face.
Treatment Areas
● Neck & Décolletage: Smooths “Turkey neck” and horizontal chest wrinkles.
● Mid/Lower Face: Tightens skin without changing facial shape.
● Hands: Restores volume to bony hands and hides visible veins.
● Body: Inner arms and abdomen (post-pregnancy laxity).
Do We Use Radiesse for Jawline?
No. Transparency is our priority.
In my clinical practice, I do not use Radiesse for volumetric jawline contouring. I strictly use it as a skin
quality agent. If a patient requires jawline definition or chin projection, I prefer Hyaluronic Acid (HA)
fillers for safer, reversible, and more precise structural results.
Plan Your Visit: Nişantaşı & Logistics
For our international patients, we ensure a seamless experience:
● Location: Our clinic is located in Nişantaşı, Istanbul’s most prestigious fashion and lifestyle
district. We are walking distance from luxury hotels like The St. Regis and The Stay.

● Short Stay: Radiesse is a “lunchtime procedure.” You can have the treatment and
immediately enjoy shopping or dining in the neighborhood.
● Flight Safety: You can safely fly the next day. The clinic is approximately 45 minutes from
Istanbul Airport (IST).
Powerful Combinations
Radiesse is effective on its own, but can be combined with other treatments for holistic results:
● Botox: While Radiesse tightens the skin structure, Botox relaxes dynamic wrinkles for a
smoother look.
● Mesotherapy / Skin Boosters: Radiesse builds the collagen scaffold, while skin boosters
provide deep hydration and surface glow.
Our Clinical Approach & Comfort
Patient safety and comfort are our top priorities.
● Pain Management: With a background in Anesthesiology, Dr. Şahin ensures that pain
management is optimized, making the procedure virtually painless.
● Customized Protocols: We avoid “one-size-fits-all” approaches; protocols are strictly
customized based on skin thickness and aging grade.
FAQ (Frequently Asked Questions)
1. Is Radiesse a filler? Technically yes, but in our clinic, we utilize it primarily as a biostimulator to
improve structure rather than add bulk volume.
2. Can Radiesse be dissolved? Unlike Hyaluronic Acid fillers, Radiesse cannot be dissolved
immediately with an enzyme. This is why choosing an expert physician is crucial for safety and
aesthetic success.
3. How many sessions do I need? Treatment Sessions:
Visible skin quality improvement can often be observed after a single session, although treatment
response varies according to individual skin characteristics. For severe laxity, a second session may
be recommended after 2-3 months.
4. When will I see results? You may see an immediate glow, but the real structural improvement
begins at 4 weeks as new collagen forms, peaking around the 3-month mark.
5. Is it painful? No. We mix the product with lidocaine (local anesthetic), and use a gentle cannula
technique to ensure minimal discomfort.
6. Can I fly after the treatment? Yes, it is safe to fly the next day. There are no pressure-related
restrictions for this treatment.
7. How long does the effect last? Results typically last between 12 to 18 months, depending on
your lifestyle and skin type.
8. Are there any side effects? Common side effects include mild swelling or bruising, which usually
resolves within a few days. The Hyperdilute technique minimizes these risks significantly compared to
standard fillers.
