Nanotechnology is a key part of making cosmetics for skin care. Essential oils are containing many different types of compounds, such as terpenoids, aliphatic chemicals, and phenol derived compounds. Due to their many useful properties, like being virucidal, bactericidal, fungicidal, local anaesthetic, anti-inflammatory, painkiller, and so on, they have been used for a long time. Because they are better for the skin, essential oils are chosen over synthetically manufactured medications made from chemicals. New nano systems like liposomes, niosomes, nano-emulsions, solid lipid nanoparticles, dendrimers, and nanospheres are used to make it easier for essential oils to get into the body through the skin. These nanocarriers allow natural components to be released in a controlled way and also make them more stable. Also, skin care items that are made with nanotechnology look nice.
