During a laser hair removal session, you'll first be positioned comfortably and protective eyewear will be provided. The technician will apply a cooling gel to the treatment area to protect the skin and reduce discomfort. Then the handheld laser device is moved across the area, delivering pulses of light to the hair follicles. Most people describe the sensation as mildly uncomfortable but not truly painful - like a light snapping sensation or warm pressure. Sessions typically last from fifteen minutes for small areas to over an hour for larger areas like legs. Discomfort varies depending on your pain tolerance, the area being treated, and your skin sensitivity. Preparation includes avoiding sun exposure for a few weeks before treatment and shaving the area beforehand but avoiding waxing or plucking. Immediately after treatment, your skin might be slightly red, which usually fades within a few hours. You should avoid sun exposure, hot baths, strenuous exercise, and certain skincare products for a few days after treatment. Most people can return to normal activities immediately, though they need to be cautious about sun protection. Side effects are generally minimal - some temporary redness, mild swelling, or slight irritation in sensitive individuals. Serious side effects are rare when the treatment is performed by professionals using appropriate settings for your skin type.
