I had microdermabrasion done and now I have a slightly swollen circle by the corner of my mouth. Is this normal? (Photo)

Speaking in general terms, microdermabrasion (unlike fractional medical microneedle therapy or dermasanding) is basically epidermabrasion, or more simply put, exfoliation. For the most part, one can achieve the same effects from a vigorous home use of a Buf Puf, Loofah or even a plain wash cloth. Of course, any abrasion, if it penetrates the skin sufficiently, can allow for the entrance of germs and infection and, if a person has a history of herpes (cold sores, fever blisters), these can be potentially be triggered, as well. Having said this, once again in general terms, because of the very superficial nature of microdermabrasion, any slight swelling or irritation that results is likely to be transient.Nevertheless, it would be wise to return to the individual who treated you to check this out.I think it would be worth pointing out that if there are certain specific cosmetic problems that are troubling, it would be better to seek consultation with a board certified aesthetic core physician in order to tailor a specific treatment regimen--both for at-home and in-office--to address those concerns. For example, if fine crinkling and superficial wrinkles are the problem, as may be the case here, a series of superficial peels might be in order, or fractional microneedle therapy, either alone or in combination with skin booster injections and neuromodulators injected very superficially. Or, if marionette lines are of concern, these can be treated easily with volumizing fillers. For more information on any of these techniques, you can check out the archives of Realself.com.

What you have is a cold sore, or hepetic outbreak. You need an antiviral medication like Valtrex or Acyclovir to treat it. If you are prone to getting cold sores, you should take the pills regularly, especially when anything is happening on or near your mouth. Like a microdermabrasion, laser treatment, or trip to the dentist. Trauma on or near the lips will often result in an outbreak. "This answer has been solicited without seeing this patient and
