What term refers to closed-lipid bilayer spheres that encapsulate ingredients targeting their delivery to specific tissues of the skin?

• A. Micelles
• B. Liposomes
• C. Emulsions
• D. Aerosols

Answer: (B)

The correct term for closed-lipid bilayer spheres that are designed to encapsulate ingredients for targeted delivery to specific tissues of the skin is liposomes. Liposomes are spherical vesicles that can carry both hydrophilic (water-soluble) and hydrophobic (oil-soluble) substances. The composition of liposomes allows for improved penetration of active ingredients into the skin, enhancing their effectiveness by ensuring they reach the desired layers. Micelles are different structures that also encapsulate ingredients but primarily focus on solubilizing hydrophobic ingredients in water and are not typically used for deep tissue delivery. Emulsions are mixtures of oil and water that can stabilize active ingredients but do not function as targeted delivery systems like liposomes. Aerosols are a method of propelling substances in a spray form and are not related to the encapsulation of ingredients within lipid bilayer structures.
