Where should a patch test for microdermabrasion be performed?

Performing a patch test for microdermabrasion on a hidden area behind the ear is a recommended practice due to several reasons. This location is typically less exposed to environmental factors and allows practitioners to observe any potential reactions in an area that is not readily visible, ensuring that any irritation or adverse reaction does not occur in a prominent area of the body.

Additionally, the skin behind the ear is similar in texture and sensitivity to many areas of the face where microdermabrasion is frequently applied. This helps in accurately assessing how the client’s skin will react to the procedure without risking visible discomfort or inflammation on more exposed skin areas.

Other locations may not provide the same level of concealment, or may present a higher risk of irritation when monitored closely. For example, areas like the forehead or inner thigh may not have the same skin type or environmental exposure as the facial area and thus may not yield reliable results. The back of the hand, while a common choice for skin testing, can still be exposed to sun and other factors that might affect skin reaction, making the area behind the ear a more suitable and safer option for this test.
