Liposomes in cosmetics

Liposomes can be used as cutaneous delivery carriers because they are tiny, unilamellar, and have membrane flexibility. As a result, liposomes are widely used in cutaneous applications, either as protective systems for active substances or to provide moisturizing characteristics. Liposomal drug-delivery systems were first employed in cosmetics in 1987, but they are now widely used in hundreds of ads in various forms such as gels, creams, and moisturizers. Liposome lipids contain moisture, therefore when the liposomal vesicle ruptures, moisture attaches to the skin surface, giving hydration. Liposomes allow us to overcome some limitations, such as low penetration, solubility, stability, duration of effect, and high side effects or expenses, while also improving some other qualities. Liposomes have been researched for a variety of cosmeceutical applications, including acne therapy, hyperpigmentation and melasma, vitiligo, and alopecia, as well as antioxidant and UV protection. Liposomal formulations have been proven in studies to be more effective in promoting therapeutic activity than non-liposomal counterparts, making them interesting candidates for enhancing the effectiveness of cosmeceutical therapies.
