Background:
Aging of the face, neck, and décolletage is a multifactorial process involving epidermal photodamage and loss of soft tissue and bony volume. Multilevel rejuvenation of these areas can be obtained by enhancing volume restoration, neocollagenesis, and tissue contraction with combined efficacy of poly-L-lactic acid (PLLA) and microfocused ultrasound (MFU, Ultherapy) treatments.
Methods:
The authors reviewed the use of PLLA and MFUs as collaborative modalities to improve the appearance of the face, neck, and décolletage.
Results:
Experienced cosmetic dermatology centers deliver PLLA and MFU in a single session to target multiple tissue planes.
Conclusions:
Concurrent treatment with PLLA and MFUs can be performed efficiently and safely; however, additional research is needed to explore the synergistic effects of these treatments. Patients may also benefit from decreased overall downtime and necessary office visits.
