![]() ![]() Lotions are composed of powder and water. Ointments work best in smooth skin regions lacking hair and on thick and dry skin lesions. ![]() Because of this effect, ointments may not always be indicated for certain regions of the skin that are naturally thinner than others (i.e. Ointments are more occlusive, which allows for better penetration of medication through the skin and higher potency. They provide great lubrication and can be used on dry skin lesions. Oils are translucent and greasy, with the latter characteristic making them cosmetically unfavorable for some patients. Ointments are mainly composed of oils and greases with a small amount of water. This is the same idea as the difference between oil and water salad dressings and a thicker one like ranch or thousand island. Because a cream is an oil in water emulsion, it requires added agents to keep the mixture stable. Additionally, certain creams can be “augmented”, meaning they are more potent and penetrate the skin deeper (i.e. Creams are particularly beneficial in the skin folds and offer a drying effect to help with wet or damp skin lesions. For these reasons, they tend to be favored by patients and frequently prescribed by clinicians. They are applicable to numerous body regions. Creams are usually white in color and easily rubbed in without leaving much of a residue.

When vehicles are combined with active medicines, you get “formulations”. For example, a vehicle with a prominent liquid component can assist with the drying of wet skin lesions through evaporation, whereas oils can provide an occluding coating to the skin and enhance the penetration of the active medicine. The inherent properties of these three ingredients is translated to the vehicle, and thus how the medicine is delivered on the skin. The primary components of vehicles include powders, oils, and liquids. Vehicles are inactive creams, lotions, solutions and/or ointments that change the properties of the medicine mixed into them – assisting its application. Instead of applying active medicine directly onto the skin, “vehicles” are combined with the chosen medication to aid in its delivery. Many skin conditions are treated with topical medications. ![]()
