A Comprehensive Review of Essential Oil–Nanotechnology Synergy for Advanced Dermocosmetic Delivery

Abstract

This review investigates the convergence of nanotechnology and essential oils in advanced dermocosmetic delivery. It outlines the pivotal role of inorganic and polymeric nanoparticles, such as titanium dioxide, zinc oxide, and gold nanocarriers, in cosmeceutical applications, facilitating slow release, deeper skin penetration, and increased retention of active compounds. Essential oils, renowned for therapeutic benefits, face translation challenges due to volatility and low water solubility. This review explores the potential use of plant nanovesicles as carriers, emphasizing safety, stability, and scalability, offering a sustainable and cost-effective industrial application. Nanomaterial integration in consumer products, particularly cosmetics, is prevalent, with nanocarriers enhancing the permeation of bioactive compounds into deeper skin layers. The review emphasizes recent nanotechnological advancements, covering nanoparticle penetration, experimental models, and therapeutic applications in dermatology, ranging from non-invasive vaccination to transdermal drug delivery. Additionally, the review delves into nanomaterials’ role in addressing skin aging, focusing on tissue regeneration. Nanomaterials loaded with cosmeceuticals, such as phytochemicals and vitamins, are explored as promising solutions to mitigate signs of aging, including wrinkles and dry skin, providing innovative approaches to skin rejuvenation. Overall, the review offers a comprehensive synthesis of essential oil–nanoparticle synergy, shedding light on the current landscape and future potential of advanced dermocosmetic delivery systems.
