There have been reports of mild to severe acne flare-ups after any fractional laser resurfacing treatment, causing some to shy away. But these can easily be avoided when you understand the causes.
Fractional resurfacing (FR) creates a microscopic wound where any bacteria can enter and result in a blemish. To avoid this, no one with active acne should undergo treatment, and the entire face should be thoroughly cleansed before treatment. In addition, the peri-oral area (around the mouth) is prone to bacteria whether from a sneeze or saliva; therefore, while an alcohol cleansing may be unpleasant, it can help to prevent acne in this region following FR.
