The décolleté — the area spanning the neck, chest, and upper breast — has long been one of the most visible signs of aging and one of the most undertreated areas in aesthetic medicine. That is changing. Radiesse, one of the most established biostimulatory injectables in aesthetics, has received FDA approval for use in the décolleté, giving providers a clinically validated, non-surgical option to address the crepey skin, wrinkles, and volume loss that develop in this area with age and sun exposure.
For patients at Evolve Med Spa, it means a treatment category that has historically been limited to lasers and topicals now has a powerful injectable option with the full backing of regulatory approval.
The U.S. Food and Drug Administration has expanded the approved indication for Radiesse (calcium hydroxyapatite, or CaHA) to include rejuvenation of the décolleté. This represents a significant milestone: Radiesse has long been used off-label in the neck and chest area, but the new approval formalizes its use in this region with clinical data supporting both safety and efficacy in décolleté skin.
The approval is specific to the diluted form of Radiesse — a hyperdilute technique in which the product is mixed with saline and lidocaine to create a more fluid consistency that spreads evenly through the superficial tissue layers of the chest, stimulating collagen and elastin rather than creating structured volume.
Unlike hyaluronic acid fillers, which physically fill and plump an area, Radiesse works as a biostimulator. The calcium hydroxyapatite microspheres in the product are suspended in a gel carrier. Once injected, the carrier provides immediate but temporary smoothing, while the CaHA microspheres stimulate fibroblasts — the cells responsible for producing collagen and elastin — to regenerate new structural tissue in the skin.
For the décolleté specifically, this mechanism is particularly well-suited because:

Ideal candidates for this treatment are patients who have noticed:
Patients who are not candidates include those with active skin infections or lesions in the treatment area, those with a history of keloid scarring, and those who are pregnant or breastfeeding. A consultation at Evolve Med Spa will determine whether Radiesse décolleté is appropriate for your skin.
The procedure is relatively straightforward and takes approximately 30 to 45 minutes:
Because Radiesse works by stimulating collagen production rather than delivering immediate volume, results develop progressively:
For context on how this compares to other skin-tightening approaches in the neck and chest area, see our post on reducing neck lines and effective treatments for a youthful neck.
Facial Radiesse is typically used in its standard (non-diluted) concentration to restore structural volume in areas like the cheeks, temples, or jawline. Décolleté Radiesse uses a hyperdilute protocol specifically designed for superficial skin rejuvenation rather than volumetric replacement. The technique, depth of injection, and intended outcome are distinct — which is why the separate FDA approval for the décolleté is clinically meaningful, not just a paperwork formality.

The treatment is well-tolerated by most patients. Topical numbing is applied before treatment, and the Radiesse formulation includes lidocaine. Most patients describe the injections as mild pressure with minimal discomfort.
Yes. Radiesse can be combined with laser resurfacing, IPL for pigmentation correction, or RF microneedling for patients who want to address multiple aspects of décolleté aging — texture, laxity, and sun damage — in a comprehensive treatment plan. Your provider at Evolve will recommend sequencing based on your priorities.
Unlike hyaluronic acid fillers, Radiesse cannot be dissolved with hyaluronidase. This makes provider selection and correct technique especially important. With proper dilution and injection depth, there is no risk of the lumping or nodule formation associated with standard-concentration Radiesse placed in the wrong tissue plane.
Both are biostimulators, but they use different mechanisms. Radiesse uses CaHA microspheres; Sculptra uses poly-L-lactic acid (PLLA). Both have been used off-label in the décolleté, but Radiesse now carries the specific FDA approval for this indication. Your provider can discuss which biostimulator is better suited for your anatomy and goals.
