Face-centric anti-aging officially expands to décolleté. Merz Aesthetics RADIESSE approved by FDA April 8, 2026 for décolleté (chest area) wrinkle indication — first US-approved procedure for the décolleté area. Calcium hydroxylapatite-based collagen·elastin self-generation stimulator as “regenerative biostimulator”. Adults 22+ indication.

Décolleté Aging Characteristics
Décolleté area:
- V-shape area below collarbone above chest
- Very high UV exposure (between shirt collars)
- Thin skin (thinner than face)
- Sleep position influence (side-sleeping wrinkle pattern)
- Rapid collagen loss (accelerates from 40s)
Distinctive aging:
- Vertical wrinkles (sleep position)
- Horizontal wrinkles (posture·gravity)
- Pigmentation (UV accumulation)
- Skin sagging (↓ collagen)
- “Décolleté wrinkles” one of most visible aging signs in 50+ women
Existing options’ limits:
- Moisturizers: surface effect only
- Retinoids: ↑ irritation·limited effect
- Sunscreens: prevention only (less effective on existing damage)
- Lasers: some effect·repeat treatments
- Fillers: no formal indication → off-label only
What Is RADIESSE
Composition:
- Calcium hydroxylapatite (CaHA) microspheres
- Carboxymethylcellulose (CMC) gel carrier
- Same as natural human bone·tooth components
Mechanism:
- Immediate effect: volume filling right after injection
- Gradual effect: CaHA stimulates collagen·elastin self-generation

Existing FDA indications:
- Facial wrinkles·hollows (especially nasolabial·marionette lines)
- Hand aging (2015 FDA)
