Narrative review outlines biomedical and cosmetic applications of microneedles for transdermal delivery, highlighting their therapeutic versatility across diverse biomaterials.
The microneedles technology has found applications in many health-related fields. For example, their application in drugs and vaccines delivery as well, as the determination of biomarkers, has been reported. They also have a place in the dermatology and cosmetic areas such as the treatment of wounds from burns, scars, acne, depigmentation, and alopecia will be shown. Microneedles are used in therapeutic applications and are manufactured using materials such as metal (steel, titanium, nickel), polymer (oly-glycolic acid (PGA), poly-lactide-co-glycolide acid (PLGA), poly-L-lactic acid (PLA), chitosan), glass, silicon, ceramic, carbohydrates (trehalose, sucrose, mannitol). Examples of application of microneedles and their advantages and disadvantages are discussed. This article is open to POST-PUBLICATION REVIEW.
