The cosmetic industry is dynamic and ever-evolving. Especially with the introduction and incorporation of nanotechnology-based approaches into cosmetics for evincing novel formulations that confers aesthetic as well as therapeutic benefits. Nanocosmetics acts via numerous delivery mechanisms which involves lipid nanocarrier systems, polymeric or metallic nanoparticles, nanocapsules, dendrimers, nanosponges,etc. Each of these, have particular characteristic properties, which facilitates increased drug loading, enhanced absorption, better cosmetic efficacy, and many more. This article discusses the different classes of nanotechnology-based cosmetics and the nanomaterials used for their formulation, followed by outlining the categories of nanocosmetics and the scope of their utility pertaining to skin, hair, nail, lip, and/or dental care and protection thereof. This review also highlights and discusses about the key drivers of the cosmetic industry and the impending need of corroborating a healthy regulatory framework, refocusing attention towards consumer needs and trends, inculcating sustainable techniques and tenets of green ecological principles, and lastly making strides in nano-technological advancements which will further propel the growth of the cosmetic industry.
化妆品行业是一个充满活力且不断发展的行业。特别是随着基于纳米技术的方法被引入并应用于化妆品中，出现了许多新颖的配方，这些配方不仅具有美容功效，还具有治疗效果。纳米化妆品通过多种输送机制发挥作用，其中包括脂质纳米载体系统、聚合物或金属纳米粒子、纳米胶囊、树枝状大分子、纳米海绵等。这些纳米材料各有特点，例如能够增加药物负载量、增强吸收效果、提高化妆品功效等。本文讨论了基于纳米技术的化妆品的不同类别，以及用于其配方的纳米材料，然后概述了纳米化妆品的类别及其在皮肤、头发、指甲、嘴唇和/或牙齿护理和保护方面的应用范围。本文还重点讨论了化妆品行业的主要驱动因素，以及迫切需要建立健全的监管框架、重新关注消费者的需求和趋势、采用可持续技术和绿色生态原则，最后在纳米技术的进步方面取得突破，这些都将进一步推动化妆品行业的发展。
