Since the microdermabrasion treatment involves extensive exfoliation on the surface of the skin, it is common to experience some sensitivity, redness, swelling, or even minor bruising for a few hours following the treatment. These side effects should be faced fairly quickly, although it is possible for those with more sensitive skin to experience sensitivity or tenderness for a couple of days, often resembling a sunburn. In most cases, patients will be able to return to work or any other regular activities without anyone else having an inkling that a procedure was completed. It is common to experience some sensitivity if using any toners, acne treatments, or medicated cleansers, often causing minor burning or stinging as the surface of the skin continues to heal, so you may wish to avoid these kinds of products for at least a day following your microdermabrasion treatment. Since your skin will be sensitive for a bit, it is very important that you apply plenty of SPF as frequently as recommended on the bottle to the treated skin whenever it may be exposed to direct sunlight to prevent incurring any sun damage while it is still healing, but this is a good rule to follow on a daily basis regardless of if your skin has recently been treated.
