Liposomes in Cosmetics: Formulation and Skin Delivery

The cosmetic industry is one of the vibrant industrial sectors as from the start of civilization people are using cosmetic products for routine body care and beauty enhancement. Different formulations are available to deliver active pharmaceutical ingredients to the site of action. But in the case of cosmetic products, the skin delivery of a drug is challenging as the skin has a lipid barrier. The evolution of liposomes has been used in the development of the drug carrier concept as a promising delivery system. Liposomes are spherical vesicles composed of phospholipids with an aqueous core that can be used as the delivery vehicle. Liposomes improve and facilitate the bioavailability of carried active components to the site of action. Traditional skincare products are difficult to absorb into the skin. However, Liposomes are used to carry the active ingredients deeper into the skin layers. Moreover, liposomes enhance the stability of active ingredient, increases dermal bioavailability, and improves the hydration of the skin.
