The length of a laser session may range from a few minutes to an hour or more depending on the size of the area being treated. How long the procedure takes depends on the area of the body involved. A small area such as the upper lip may take several minutes. A larger area such as the back or legs may require several hours.
Since laser tends to treat hair follicles that are in an active growth phase, more than one treatment may be required to disable hair follicles that subsequently enter this growth phase. During the procedure, laser light will be delivered through a hand held piece attached to a laser console. You may experience a stinging sensation as the laser pulse is delivered. To reduce discomfort, the cooling system automatically removes heat from the surface of your skin before, during and after the laser exposure. The process can take from just a few minutes for an upper lip to several hours for a full back and legs.
Laser treatment itself may cause a slight tingling sensation. Most patients tolerate the procedure well. But because some areas of the body are more sensitive than others, topical anesthesia can be an option. The appearance of the treated area immediately after the laser session will vary from patient to patient depending on the extent of treatment and skin type. Immediate after-effects, if any, are minor. They may include redness and swelling, which disappear in a short time. Most people return to normal activity right away.
During the procedure, you wear goggles to protect your eyes from accidental exposure to laser light. The procedure causes a slight charring of your stubble. You may notice a strong odour of singed hair, which is normal. Afterwards, you may experience some temporary redness and swelling.
