Nature’s nano-shield: plant-based essential oil nano-emulsions as potent defenders against microbial invaders and skin wounds

Abstract

As the demand for safer and more natural skincare solutions grows, the fusion of ancient botanical wisdom with cutting-edge nanotechnology is unlocking unprecedented potential in skin therapeutics. Plant-based essential oils, long revered for their healing properties, have transcended traditional uses in massage and beauty treatments to emerge as powerful bioactive agents against microbial infections and skin disorders. However, their volatile nature and limited stability have posed significant challenges until now. This review explores the innovative field of essential oil nano-emulsions, in which natural substances are encapsulated within nanoscale systems to amplify their efficacy, stability, and skin penetration. Through in-depth investigation and comprehensive presentation, the presence of monoterpenoids that contribute to both the aroma and biological activities of essential oils is documented. The subsequent analysis introduces advanced methods used to create nano-emulsions containing essential oils, the pivotal role of surfactants, and the exceptional antimicrobial, anti-inflammatory, and wound-healing properties exhibited by these nano-emulsions. This is the first review that comprehensively presents essential oil nano-emulsions as a promising approach to address the imminent risks of skin infections and chronic wounds, thereby offering a bold new frontier in combating complex skin disorders. The future of skincare is unfolding, and it promises to be both natural and revolutionary.
