The following is a list of known possible laser hair removal risks:
Incomplete hair extraction or regrowth - Unfortunately, even the most effective cosmetic treatments don't provide the best results for everyone. While it is important to follow the suggested guidelines and undergo 6 to 8 treatments for best results, patients with very light hair may not enjoy complete success. Improperly calibrated machinery and lasers may also be the cause of unsuccessful removal. It is a common myth that laser treatment can bring about an accelerated growth cycle. This misconception is not based on fact and there have been no reported incidents of increased hair growth after treatment.
Hyperpigmentation or hypopigmentation - The darkening or lightening of the skin after treatment is usually a temporary result but can, in extreme cases, last a considerable time or prove permanent. Because of the type of lasers used during the removal procedure, those with dark skin run the greatest risk of lightening upon completion.
Textural changes to the skin - Lasers may cause the characteristics and feel of the dermis to change. This is a very rare outcome of laser treatments.
Bleeding - Cooling gel and properly calibrated laser equipment are important components of a safe laser treatment outcome. If the dermatologist performing the procedure fails to customize the laser to the patient's skin type, or fails to use the cooling gel prior to beginning treatment, bleeding may occur. Fortunately, this is rare.
Infection - Sometimes, though rarely, the site of the laser treatment will blister following the procedure. These blisters can become infected if left untreated. A simple antibiotic cream or ointment, applied to the affected areas, will protect the sore skin and ward off contamination.
Scarring - Each person's skin has a different ability to heal. Some mend quickly and easily while others run the risk of permanent scarring. A blister or burn after treatment may scar, depending on one's own skin type. If, during the laser process, the patient is experiencing noticeable pain or burning, it is important that the practitioner by alerted immediately. The laser being used may need to be re-calibrated so that the powerful beams don't further burn the surface of the skin, therefore preventing the possibility of scarring.
Although there are risks of laser hair removal, the chance of experiencing one or more of these risks is minimal when an experienced and certified doctor is used to perform the procedure. A dermatologist who uses the newest form of laser technology can provide a safer and more effective service to his or her patients.
