Researchers from Egypt explore a unique area of medicine and 3D printing, releasing findings from their study in the recently published ‘Characterization and Pharmacological Evaluation of Anti-Cellulite Herbal Product(s) Encapsulated in 3D-Fabricated Polymeric Microneedles.’
While many studies have been produced regarding 3D printed medical devices, pills, and delivery systems, in this latest research the concern is centered on good skin health, and the elimination of cellulite—the scourge of many women, felt around the world. Investigating the use of microneedles, the researchers developed a new, painless alternative in the form of a micromold capable of delivering benefits from minerals, and phenolic and flavonoid contents.
While only a small percentage of men are affected by cellulite, 90 percent of women begin to see this skin condition after entering their 20s. Made up of fat, cellulite presents itself due to numerous conditions—from lack of circulation to inflammatory responses. Many creams and different products are markets; however, most treatments are ineffective unless they can actually penetrate the epidermis. The authors point out that microneedles are found to be effective, along with offering the benefits of both invasive and non-invasive routes—whether through injections or patches.
Micro-molding of MNs is one of the most popular techniques due to easy scalability and reproducibility. SLA 3D printing is often used for the fabrication of the master molds. For this study, the researchers tested extracts like V. agnus-castus and T. indica, evaluating cellulite management.
“The microneedle delivery system represents a novel tool that is safe, efficient and self-administered, without the need for suctioning the excess fat using high-cost ultrasonic liposuction and decreasing the systemic side effects of oral slimming medications,” explained the researchers.
MNs were tested for mechanical strength and then assessed regarding morphological characterization. Dried extracts were formulated and then mixed with water, yielding four different medicated varieties that were poured into the molds and then oven-dried for 24 hours. Ultimately, the arrays consisted of 100 needles.
“When the MNs were inserted into the skin, the dissolvable polymeric MNs started to quickly and completely dissolve in the skin without the generation of sharp biohazardous waste. The rapid dissolution of the MNs was accompanied by a rapid release of the encapsulated drugs, consistent with previous reports, as the amount of the encapsulated extract in the prepared MNs increased, the amount of extract that permeated through the cellulose membrane increased,” said the researchers.
“MNs loaded with T. indica extract may help to ameliorate the skin appearance by reducing the inflammatory parameters and improving the antioxidant power. The transdermal delivery of anti-cellulite drugs can be ameliorated through large-scale experimental trials. Ultimately, the use of microneedles offers a simple and relatively cheap way for drug delivery, thus encouraging their wider use in biomedical applications.”
