Other factors can influence the treatment process, but these are best evaluated and discussed by a physician in person. Most patients describe the experience as a series of slight pin pricks to the skin. The majority of patients tolerate this without any use of anesthetics. Within 30 minutes of treatment, the skin may become pink or red, resembling a mild sunburn. This may last from a few hours to one day.
Hair grows in cycles.
At any given time, some hair follicles are dormant. The laser only affects hair in its growth phase. In other words, the laser only disables those hair follicles that are actively producing hair at the time of treatment. Usually, more than one session is necessary to obtain the desired results. Only your physician can help you decide if laser hair removal is appropriate for you.
