Microdermabrasion is a non-invasive procedure used to improve the skin's appearance by exfoliating the top layer. During the treatment, it is important to monitor the client's skin reaction to ensure their comfort. Stopping the procedure before erythema, which refers to redness of the skin caused by increased blood flow, is vital.

When erythema starts to develop, it indicates that the capillaries are dilating and the skin is becoming irritated. Continuing the procedure beyond this point can lead to increased discomfort and potentially greater skin irritation or damage. By stopping before erythema occurs, the practitioner ensures that the skin remains comfortable and minimizes the risk of adverse effects.

Other options do not provide a definitive threshold to prevent discomfort. Feeling tightness may not directly correlate with the appropriate stopping point, as some level of tightness is often expected during treatment. Similarly, sweat can occur due to the heat generated during microdermabrasion and is not necessarily an indicator of discomfort or skin irritation. Finally, stopping before any redness appears aligns closely with the correct answer but is less specific than stopping before erythema, as minimal redness may not indicate discomfort in all clients. Therefore, recognizing and responding to the onset of erythema is
