Injectable Platelet-Rich Fibrin and Hyaluronic Acid Mesotherapy for Management of Actinic Elastosis of Lower Eyelids: A Case Series

Rejuvenating the skin on the lower eyelids is often complicated. Treatment alternatives that have been practiced in the past had several complications. Additionally, they were not completely effective in addressing skin aging or actinic elastosis symptoms such as dark circles under the eyes. A minimally invasive therapy approach that improves the above-mentioned issues in a desirable way has been discussed in this case series. The patients selected were of the age group between 20-40 years who had actinic elastosis of the lower eyelid. The patients were injected twice at one-month intervals with a combination of injectable platelet-rich fibrin (iPRF) and hyaluronic acid. The patients were examined on the day of treatment and one month after the second injection. A progressive improvement in the esthetic outcome and a high level of patient satisfaction were observed. Apart from the predicted visible swelling right away following the iPRF injection. The outcomes have shown that a series of iPRF with hyaluronic acid injections in the lower eyelid region is a safe, proficient, pain-free, simple and rapid treatment option for actinic elastosis.

Applications and prospects of microneedles in tumor drug delivery

As drug delivery devices, microneedles are used widely in the local administration of various drugs. Such drug-loaded microneedles are minimally invasive, almost painless, and have high drug delivery efficiency. In recent decades, with advancements in microneedle technology, an increasing number of adaptive, engineered, and intelligent microneedles have been designed to meet increasing clinical needs. This article summarizes the types, preparation materials, and preparation methods of microneedles, as well as the latest research progress in the application of microneedles in tumor drug delivery. This article also discusses the current challenges and improvement strategies in the use of microneedles for tumor drug delivery.
