Rosacea is a chronic inflammation of facial skin characterized by redness, prominent blood vessels, swelling, and/or skin eruptions that look similar to acne. Microdermabrasion can be used to decrease the redness associated with rosacea. However, if you have been diagnosed with rosacea and are considering microdermabrasion, you should consult a dermatologist or cosmetic surgeon prior to treatment because microdermabrasion can negatively affect active rosacea.
