Written Laser Hair Removal Practice Exam

According to the text, active acne should not be lasered over because it can potentially cause damage to the skin and aggravate the acne. Lasers work by targeting melanin or pigment in the skin, and actively inflamed acne can contain high levels of melanin which can absorb the laser energy and result in burns or discoloration. Tattoos, scar tissue, and hairy areas can all be safely treated with lasers as long as the appropriate settings are used. However, active acne should be avoided until it has cleared up to prevent any potential complications.
