Vesicles: Potential Nano Carriers for the Delivery of Skin Cosmetics

The document from 2017 reviews the use of vesicular carriers like liposomes, niosomes, transferosomes, and ethosomes in enhancing the delivery of active ingredients in skin cosmetics. These carriers can improve skin penetration, provide sustained release, and add cosmetic benefits due to their biodegradable and minimally toxic nature. They show promise in treating conditions like hyperpigmentation, psoriasis, and alopecia, with studies demonstrating their effectiveness in delivering active ingredients more effectively and with fewer side effects. For instance, a study involving 30 women showed liposomal tranexamic acid was more effective than conventional hydroquinone in treating melasma. Vesicular systems also offer controlled release, reduced toxicity, and increased stability for anti-aging products, with further research needed to understand their interaction with skin lipids and penetration effects. The document concludes that while vesicular carriers have potential benefits, more human studies are required to ensure consumer health and the efficacy of cosmetic products using these novel vesicles.
