The cosmetic industry is rapidly rising worldwide. To overcome certain deficiencies of conventional cosmetics, nanomaterials have been introduced to formulations of nails, lips, hair, and skin for treating/alleviating hyperpigmentation, hair loss, acne, dandruff, wrinkles, photoaging, etc. Innovative nanocarrier materials applied in the cosmetic sector for carrying the active ingredients include niosomes, fullerenes, liposomes, carbon nanotubes, and nanoemulsions. These exhibit several advantages, such as elevated stability, augmented skin penetration, specific site targeting, and sustained release of active contents. Nevertheless, continuous exposure to nanomaterials in cosmetics may pose some health hazards. This review features the different new nanocarriers applied for delivering cosmetics, their positive impacts and shortcomings, currently marketed nanocosmetic formulations, and their possible toxic effects. The role of natural ingredients, including vegetable oils, seed oils, essential oils, fats, and plant extracts, in the formulation of nanocosmetics is also reviewed. This review also discusses the current trend of green cosmetics and cosmetic regulations in selected countries.
全球化妆品行业正在迅速崛起。为克服传统化妆品的某些缺陷，纳米材料已被引入指甲、嘴唇、头发和皮肤的配方中，用于治疗/缓解色素沉着、脱发、痤疮、头皮屑、皱纹、光老化等问题。应用于化妆品领域以承载活性成分的新型纳米载体材料包括非离子表面活性剂囊泡、富勒烯、脂质体、碳纳米管和纳米乳液。这些材料具有多种优势，如稳定性提高、皮肤渗透性增强、特定部位靶向性以及活性成分的持续释放。然而，在化妆品中持续接触纳米材料可能会带来一些健康危害。本文综述了用于递送化妆品的不同新型纳米载体、它们的积极影响和缺点、目前市场上的纳米化妆品配方以及它们可能的毒性作用。还综述了天然成分，包括植物油、种子油、精油、脂肪和植物提取物在纳米化妆品配方中的作用。本文还讨论了绿色化妆品的当前趋势以及部分国家的化妆品法规。
