2. Rare Risks, Side Effects, Complications of Laser Hair Removal

Burns

Minor burn from laser hair removal treatment has become increasingly common. Around 4,000 laser adverse event are recorded annually in the UK and most of them are associated with burn by lasers or IPL. There are three degrees of burns from laser treatment, the first degree burn is not very serious and will heal with time. However, the second and third degree burn can lead to Blistering, Crusting, Hyper / Hypo Pigmentation, and Scarring of skin. If it feels extremely hot and is not cooling down or extremely pain during the laser treatment, you should alert your technician.

Slight Crusting / Scab Formation

Sometimes laser can irritate hair follicles, such that slight bleeding or the formation of scabs occur. Usually, it will occur in people who have ingrown hairs. However, it was also reported that up to 30% of patient with lighter skin treated with Long-pulsed Ruby and Alexandrite lasers. The main reason behind the crusting is connected to over treating an area with the laser.

Blistering

If you experience blistering after your laser hair removal treatment, you could have a second-degree burn. The most reason cause of it is the technicians who are not experienced or qualified in the laser procedure. Blisters are very painful and they bring intense discomfort to anybody and when untreated, it may result to a risk of scarring and pigment changes to the skin.

Hyperpigmentation

Hyperpigmentation refers to the darkening of skin. It is a frequently encountered complication in patients who have darker skin with excessive laser energies and inadequate epidermal cooling. Usually, it will fade within three months though it can last for six to eight months. Recent reports over the past decade have shown decreased the Hyperpigmentation with the longer wavelength lasers such as the Diode or Nd:YAG and the risk is higher with IPL and Ruby than with other lasers.

Hypopigmentation

Hypopigmentation refers to the lightening of skin due to the laser beam is partially absorbed into the skin instead of being absorbed into the hair follicle. The light rays can ruin or defect the melanin of the skin and by that harm the ability of the body to manufacture skin tone. The lightning of skin tone generally lasts up to two months and may be permanent in some cases. People with darker skinned are more vulnerable to hypopigmentation.

Scarring

Generally in the rare case of a scarring after laser hair removal treatment. However, there have been numerous articles in the press of patients being left with scars following laser treatment. The most common cause is improper use of the laser machine. The Alexandrite Laser for light to medium skin, the Diode for light to tanned tones, and the Nd:YAG for darker skin. The secondly is the experience and training of laser operator.

Cause Acne, Pimple

The hair plays in protecting our skin from bacteria as it keeps sebaceous glands clear of buildup and clogging. Patients may experience acne in places they have never experienced it before such as the back, genital regions or under the arms. However, it is certainly not long-lasting.

Laser-induced Hypertrichosis

Current research indicates that the leading cause for the stimulation of hair growth is treated with the wrong laser or if it's on the wrong setting. Heat stimulation can activate dormant follicles and the fine hairs will absorb a certain amount of energy, causing some damage. If using the sub-optimal energies lasers to remove hair, they can not enough to completely destroy the follicles. In trying to heal this damage, the follicles can be strengthened and increased hair growth! This is why laser is never good to treat at low settings or too fine hairs.

Infection

Infection following Laser / IPL treatments can lead to scarring and permanent discoloration of the skin. Although it is unusual, but bacterial, fungal and viral infections can occur due to the superficial skin is injured by lasers. The risk of infection is increased if your skin starts to blister after laser treatment. If you are exposed to the sun for lengthy periods of time before the healing process of laser treatment is over, you are more likely to develop an infection.

Purpura (Bluish Skin Discolorations)

Purpura is the bleeding under the skin leaving purple spots or rashes. The laser hair removal is not that advisable for individual who have tanned skin because purpura is the most crucial problem that they could encounter after treatment. The good news is that the purpura is typically temporary, usually it disappears in 3-5 days.

Bruising

Bruising is a relatively rare of laser hair removal risks. Patients with sensitive skin that bruises easily may see bruising after treatment. Diabetics, pre existing skin or circulatory issues are prone to bruising due to poor blood circulation. Bruising can sometimes be avoided by not taking anticoagulants such as aspirin or avoiding Vitamin E for 2 weeks prior to laser treatment.

Eye Injury

Eye Injury is a long term and harmful side impact, however it can also be extremely rare. Any direct or stray pulse of light were to enter the eye it could damage the retina and potentially lead to blindness. We DO NOT recommended to laser treat anywhere around your eye socket, marked by the orbital bone. Because the light can touch your eyes and the risk of Uveitis will be increased. This problem can happen when using a longer wavelength laser and it might cause redness of the eye, blurred vision, sensitivity to light, dark, floating spots along the visual field and eye pain.
