Rosacea is a prolonged inflammation of facial skin characterized by redness, prominent blood vessels, swelling, and/or skin flare-ups 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, please consult with a dermatologist or skin specialist as microdermabrasion may have a negative result.
