• Folliculitis: Inflammation of the hair follicles due to irritation or infection is an adverse effect largely associated with hair removal. Depending on the laser system and skin type treated, the incidence rate for folliculitis can range from <1% to as high as 35% [106].
• Blistering and Crusting: These dermal events are generally associated with using too high a fluence level than indicated for a particular skin type [116]. With the appropriate selection of the laser parameters for the skin type of the subject being treated, blistering and crusting are considered rare events [130].
• Scarring: With nonablative laser treatments, scarring is also a rare event and associated with excessive fluences and secondary events such as infection.
