liposomët

Liposomes are microscopic spheres made of lipid bilayers, similar in structure to cell membranes. They are formed when phospholipids in an aqueous solution spontaneously assemble into spherical structures. These structures can encapsulate hydrophilic substances in their aqueous core and lipophilic substances within their lipid bilayer. This unique ability makes them valuable in various applications, particularly in medicine and cosmetics.

In medicine, liposomes are primarily used as drug delivery vehicles. Their biocompatibility and biodegradability make them attractive alternatives to other delivery systems. By enclosing therapeutic agents, liposomes can protect them from degradation, improve their solubility, and control their release within the body. This targeted delivery can enhance drug efficacy and reduce side effects, especially for potent drugs or those with a narrow therapeutic window. They are employed in delivering chemotherapy agents, antifungal drugs, and vaccines.

In the cosmetic industry, liposomes are used to deliver active ingredients like vitamins, antioxidants, and moisturizers into the skin. The lipid bilayer structure can help these ingredients penetrate the stratum corneum, the outermost layer of the skin, more effectively. This enhanced delivery can lead to improved hydration, reduced signs of aging, and better overall skin health. The stability and ability to encapsulate both water-soluble and oil-soluble compounds make them versatile components in skincare formulations. Research continues to explore new ways to utilize liposomes for drug delivery and other technological advancements.
