Effects of Energy-Based Devices on HA Filler

Heat-Based Devices and Dermal Fillers

A study using abdominoplasty skin samples revealed that the heat of fractional microneedle radiofrequency (RF) devices can cause thermal damage to hyaluronic acid (HA) fillers. For “Histologic Effects of Fractional Laser and Radiofrequency Devices on Hyaluronic Acid Filler,” published in the April issue of Dermatologic Surgery, Sarah Ham Hsu, MD, Hye Jin Chung, MD, MMS, and Robert Weiss, MD, divided abdominoplasty skin samples into eight zones. They injected HA filler intradermally into seven zones with one zone left untreated to act as control.

Laser-Assisted Delivery of Antioxidants Improves Postprocedure Healing

Laser-Assisted Delivery of Antioxidants Improves Postprocedure Healing

In a study published in Lasers in Surgery and Medicine (March 2016), Jill Waibel, MD, et al, investigated whether laser-assisted delivery of vitamins C and E plus ferulic acid immediately following fractional ablative laser treatments would improve wound healing. Their secondary objectives were to evaluate the potential molecular markers involved in that wound-healing process.

Lumenis Launches Nonablative ResurFX System

At the 2015 International Master Course on Aging Skin (IMCAS) Annual World Congress, Lumenis debuted its new ResurFX laser system for nonablative fractional skin resurfacing treatments. The standalone desktop platform uses customized treatment parameters that allow providers to choose from more than 600 combinations of shape, size, density and energy delivery. The ResurFX is effective in a single pass and does not require disposables.

Breaking the Barrier

Transepidermal delivery of topicals is gaining ground in aesthetic medicine.
Breaking the Barrier

Both fractional lasers and microneedling have been shown to stimulate collagen production by creating tiny columnar wounds that penetrate deep into the dermis. Researchers are now investigating protocols that allow them to use these same microchannels to deliver healing and rejuvenating substances through the skin barrier.
