Article Synopsis
- High-intensity focused ultrasound (HIFU) and radiofrequency (RF) are both non-invasive treatments for skin rejuvenation, but their combined effectiveness had not been previously studied.
- In a trial with 22 Korean adults, one side of the face received HIFU treatment alone while the other side received a combination of HIFU and bipolar RF, allowing for a direct comparison of results.
- The study found that while HIFU alone improved various skin parameters, combining it with bipolar RF provided even better results in terms of reducing pore size, enhancing skin elasticity, and decreasing the depth of eye wrinkles.
Recent studies have shown that prostaglandin D2 (PGD2) and its nonenzymatic metabolite, 15-deoxy-Δ(12,14)-prostaglandin J2 (15-dPGJ2), inhibit in vitro growth of explanted human hair follicles and inhibit hair growth in mice through the GPR44 (DP2). However, the underlying mechanism is still unclear. In this study, we first investigated the expression of DP2 in human hair follicles and in cultured follicular cells.
