Which of the following is NOT a method of exfoliation?

The method that is identified as not being a type of exfoliation is the physical option. Exfoliation is the process of removing dead skin cells from the surface of the skin, and there are several recognized methods for achieving this, each with its own unique characteristics.

Enzymatic exfoliation uses natural enzymes found in fruits like papaya or pineapple to break down the bonds between dead skin cells, allowing them to be sloughed away gently without harsh scrubbing. Chemical exfoliation involves the use of acids or other chemicals to dissolve dead skin cells and improve skin texture and radiance. Mechanical exfoliation refers to the use of physical methods, such as scrubs, brushes, or microdermabrasion devices, to manually remove dead skin from the surface.

It's essential to understand the terminology used in esthetics, as the word "physical" encompasses methods that rely on manual or mechanical means to achieve exfoliation, rather than implying the absence of exfoliation altogether.
