Laser hair removal has been one of the most common aesthetic procedures more for the last 25 years. It gained popularity because it is minimally invasive and has long-term results with minimal complications.
Although those lasers were developed for hair removal, they have become one of the essential dermatology tools for a wide range of very severe skin and hair disorders.
Hair removal lasers operate on the principle of selective thermolysis, targeting the pigment. The hair follicle is destroyed when a laser beam is absorbed into melanin. Ruby, Alexandrite, Diode, Neodymium laser or IPL system can be used.
Skin conditions closely related to inflammatory processes at the hair follicle can also be treated with hair removal lasers.
The use of these lasers in children with a congenital problem of the hair follicle is proven to be completely safe with minimal period of recovery.
Pilonidal sinus is a painful condition, possibly with a genetic predisposition. It is a small hole or tunnel in the skin in the cleft at the top of the buttocks that fills with fluid or pus, causing the formation of a cyst or abscess. It requires a surgical treatment, but the possibility of recurrence is as high as 15%.
Over the years, laser hair removal of the affected area has been proven to significantly reduce the possibility of recurrent complication of the pilonidal sinus. In one study with a five-year follow-up, there was no recurrence of pilonidal sinus after 3 treatments with diode laser for hair removal.
Hidradenitis suppurativa is a condition that causes painful bumps under the skin in the hair follicles near some of the sweat glands. It is also called inverse acne because it occurs in the armpits, groin, sitting area and breasts. In addition to surgical interventions, antibiotic and tretinoin therapies, this painful condition is sometimes very difficult to treat.
A significant improvement in hidradenitis is observed after laser hair removal. Two months after two laser hair removal treatments, the inflammation and scar tissue are reduced by as much as 32%. After 4 laser hair removal treatments followed by a CO2 laser , it enters the remission as it was observed during a three-year study.
Dissecting cellulitis is a chronic inflammatory disorder of the scalp, very difficult to treat. Even after the surgical therapy it has a tendency of recurring. Earlier, radiation therapy was used, but due to long-term complications it was discontinued.
Hair removal lasers successfully remove purulent collections without any complications, even increased hair growth was observed a year after the treatments.
Folliculitis or ingrown hairs can be completely resolved with laser hair removal. The very first laser treatment significantly changes the amount of ingrown hairs in the affected area. With three treatments in 90% of patients, ingrown hairs disappear permanently.
Folliculitis that affects the scalp is characterized by inflammatory papules and pustules accompanied by scar tissue.
Using low energy on the laser does not damage the hair follicle, and the disease is quickly enters into remission.
Acne keloidalis nuchae
Acne that causes scarring on the neck is very successfully treated with laser hair removal.
Keratosis pilaris or “chicken skin” is a genetically predisposed disorder caused by keratin accumulation in the hair follicles characterized by small bumps and redness on the thighs, upper arms, face. It’s resistant to therapy. After three diode laser treatments, the skin texture significantly improves.
These lasers are also used in gender affirming surgery as well as urethral prolapse.
Long-term use of these lasers has showed many benefits of this therapy with almost no side effects, provided that lasers are used adequately.
