When should microdermabrasion cease before a procedure begins?

Microdermabrasion should cease before erythema begins because the skin should not be overly irritated or inflamed when preparing for subsequent procedures. Erythema indicates a reaction or inflammation of the skin, which can compromise the skin's barrier and increase sensitivity. If microdermabrasion is performed too close to the start of another treatment when erythema is present, it may lead to increased discomfort or adverse reactions during that treatment. This approach ensures that the skin remains calm and ready for further evaluation or treatment, maximizing the effectiveness and minimizing potential complications of the subsequent procedure.
