Risks & How you Prepare
Laser hair removal doesn’t guarantee permanent hair removal. The most common side effects of laser hair removal include:
- Skin irritation. Temporary discomfort, redness and swelling are possible after laser hair removal. Any signs and symptoms typically disappear within several hours.
- Pigment changes. Laser hair removal might darken or lighten the affected skin, usually temporarily. Skin lightening primarily affects those who have darker skin, especially if an incorrect laser is used at an incorrect setting.
Rarely, laser hair removal can also cause blistering, crusting, scarring or other changes in skin texture.
If you are planning on undergoing laser hair removal, you should limit plucking, waxing, and electrolysis for six weeks before treatment. That’s because the laser targets the hairs’ roots, which are temporarily removed by waxing or plucking. You should also avoid sun exposure for six weeks before and after treatment.
What can you Expect & Results
Just before the procedure, your hair that will be undergoing treatment will be trimmed to a few millimeters above the skin surface. The laser equipment will be adjusted according to the color, thickness, and location of your hair being treated as well as your skin color.
- Precision. Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged.
- Speed. Each pulse of the laser takes a fraction of a second and can treat many hairs at the same time. The laser can treat an area approximately the size of a quarter every second. Small areas such as the upper lip can be treated in less than a minute, and large areas, such as the back or legs, may take up to an hour.
- Predictability. Most patients have permanent hair loss after an average of three to seven sessions
Results of laser hair removal vary greatly from person to person. Multiple treatments can prolong the duration of hair loss — up to years in some cases — but hair regrowth is still possible. For best results, you might need four to six treatments spaced a number of weeks apart.
