During a BBL laser treatment, your skin will be exposed to quick blasts of high-intensity light. Most people say it feels like a warm sensation, but some have compared it to a snap from a rubber band. The level of discomfort you experience may depend on where the treatment is applied. For example, the upper lip may be more sensitive than your arm or leg. Overall, there’s little-to-no pain during laser skin treatment. Your technician will even use topical numbing cream to reduce discomfort even further.
