Hyperdilute Radiesse Injections in Ashburn, VA

At Mountcastle Medical Spa and Plastic Surgery in Ashburn, VA , we are proud to offer advanced injectable treatments designed to restore volume, improve skin texture, and stimulate collagen. One of the most innovative approaches is hyperdilute Radiesse®, a treatment that blends science, artistry, and natural results.

What Is Hyperdilute Radiesse?

Radiesse® is an FDA-approved injectable filler made of calcium hydroxylapatite (CaHA) microspheres suspended in a water-based gel. Traditionally, Radiesse has been used to restore lost volume in deeper facial folds and to contour areas like the cheeks, jawline, and hands.

When Radiesse is diluted with saline and lidocaine, it transforms from a volumizing filler into a biostimulatory injectable. This is what we call hyperdilute Radiesse. Instead of simply filling wrinkles, the diluted formula spreads more evenly beneath the skin, stimulating collagen and elastin production over time. The result is firmer, tighter, more youthful-looking skin with a smoother texture.

Areas We Can Treat with Hyperdilute Radiesse

Hyperdilute Radiesse is versatile and can be used to improve skin quality and firmness in multiple areas of the face and body:

• Face – Cheeks, jawline, temples, and smile lines for improved contour and tightening
• Neck – To smooth “tech neck” lines and restore firmness
• Décolletage – To soften chest wrinkles and crepey skin
• Upper arms – Commonly used for “crepey” texture and mild skin laxity
• Buttocks – As part of a non-surgical butt lift to enhance contour and improve skin texture
• Thighs – To improve cellulite and skin quality
• Knees – For tightening sagging or wrinkled skin around the knees

This wide range of applications makes hyperdilute Radiesse one of the most comprehensive biostimulatory treatments available today.

How Hyperdilute Radiesse Works: The Science Behind It

Pathophysiology of CaHA Injections

Radiesse contains calcium hydroxylapatite microspheres — the same mineral compound found naturally in bones and teeth. When injected, these microspheres act as a scaffold beneath the skin.

1. Initial effect – Patients may notice some immediate improvement from the carrier gel, but this effect is temporary.
2. Collagen stimulation – As the gel is absorbed, the CaHA microspheres remain and stimulate fibroblasts to produce new collagen (Type I and Type III) and elastin.
3. Long-term remodeling – Over the next 3–6 months, the treated area becomes firmer, thicker, and more elastic, thanks to this new structural support.
4. Gradual biodegradation – Eventually, the CaHA microspheres break down into calcium and phosphate, which are safely metabolized by the body.

This process makes hyperdilute Radiesse unique: it does not just fill wrinkles — it changes the quality of the skin.

History of Radiesse and the Hyperdilute Technique

Radiesse was first approved by the FDA in 2006 for soft tissue augmentation and correction of moderate to severe facial folds. Over the years, providers noticed its exceptional collagen-stimulating effects.

By the mid-2010s, aesthetic injectors began experimenting with dilution techniques — combining Radiesse with saline and lidocaine in various ratios. These hyperdilute formulas allowed for broader distribution under the skin, targeting larger areas with the goal of improving skin tone and elasticity instead of just volume.

Today, hyperdilute Radiesse is a well-established technique taught in advanced injector courses and used worldwide as a powerful option for non-surgical rejuvenation.

Pros and Cons of Hyperdilute Radiesse

Pros

• Collagen stimulation – Improves skin quality from within, not just superficially
• Versatility – Effective for both face and body areas
• Long-lasting – Results often last 12–18 months or longer
• Natural results – Gradual improvement avoids an “overdone” look
• Safe and biocompatible – Calcium hydroxylapatite is naturally metabolized by the body

Cons

• Not instant – Full results take several months as collagen builds
• Series of treatments – Best results often require
