You may experience swelling, sensitivity, and redness after a laser hair removal session. This can be treated with icepacks and over-the-counter pain medication to ease discomfort. Avoid using perfumes or lotions on the treatment area in the days following your treatment. Do not expose the area to excessive sunlight in the months before and the days after your treatment. If you’re planning to have laser hair removal on an area that is typically exposed, like your face, be sure to use sunscreen consistently in the weeks leading up to your treatment session.
