Abstract

Calcium hydroxylapatite (CaHA) dermal filler is used for a variety of aesthetic treatments; however, the safety and effectiveness of diluted CaHA for the treatment of décolleté wrinkles have not been established. To demonstrate the effectiveness and safety of diluted CaHA (Radiesse; 1:2 CaHA:saline) injection for the improvement of décolleté wrinkles in females. Eligible females with moderate or severe ratings on the Merz Aesthetic Scale (MAS) Decollete Wrinkles - At Rest received up to 3 injection cycles of diluted CaHA either 8 weeks apart (3 injection cycles) or 16 weeks apart (2 injection cycles). Effectiveness was evaluated by improvement on the MAS. Adverse events were recorded over a 52 week period. Sixteen weeks after the last treatment, the response rate (1-point improvement or greater) on the MAS Decollete Wrinkles - At Rest was 73.5% (P<0.0001; pooled sample) for all patients. The use of diluted CaHA in the decollete also demonstrated a favorable safety profile. Diluted CaHA is a safe and effective treatment for the improvement of decollete wrinkles in females.J Drugs Dermatol. 2024;23(7):551-556.  doi:10.36849/JDD.8261.
