What does the number of passes in microdermabrasion depend on?

The number of passes in microdermabrasion primarily depends on the thickness of the skin. When performing microdermabrasion, the practitioner evaluates the client's skin type and condition, which helps determine how many passes are needed to achieve the desired exfoliation effect without causing damage. Thicker skin generally allows for more passes because it can endure a greater degree of exfoliation, while thinner or more sensitive skin may require fewer passes to avoid irritation or adverse reactions.

While factors such as pain tolerance, skin hydration levels, and the presence of acne can influence how the procedure is performed, they do not directly dictate the number of passes. Pain tolerance might affect the client's experience but does not change the technique used. Similarly, the hydration levels of the skin or the presence of acne can inform the overall treatment approach, but they do not serve as direct indicators of the number of passes necessary for effective microdermabrasion. Thus, understanding the thickness of the skin becomes crucial for determining the appropriate treatment intensity.
