Following ultraviolet rays, the Phototherapy Center of National Taiwan University Hospital recently tried low-energy lasers to treat vitiligo and pimples, and near-infrared rays to treat baldness and festering wounds, which proved to be better than traditional treatments, and were non-invasive and had fewer side effects. Take alopecia areata as an example. After a month of irradiation, the patient will no longer lose hair, and can grow new hair. Japanese studies have shown that this therapy has great potential for development.
National Taiwan University Hospital established the “Integrated Phototherapy Center” in November last year. Dermatologist Cai Chengfang of the center pointed out that in the past, ultraviolet radiation was commonly used to treat psoriasis, severe eczema, and skin lymphoma. Energy lasers are used to treat vitiligo, and they are used in “re-medicine” with remarkable results.
This low-energy laser (such as helium-neon laser) is used in the treatment of leukoplakia patients. It can increase the proliferation of melanocytes and enhance the movement of melanocytes in hair follicles. Therefore, for more difficult leukoplakia, the cure rate can reach 70%. There are no side effects, and the complexion after recovery is extremely natural.
In addition, the use of low-energy lasers to treat red, swollen and purulent pimples is also effective. Cai Chengfang said that low-energy laser light actually has the effect of slightly reducing inflammation and activating cells, so it can achieve sterilization and swelling reduction effects. It is a new choice for people who do not want to take antibiotics to treat acne.
As for the treatment of baldness, Japanese studies have found that near infrared rays can increase hair strength and reduce hair loss. Cai Chengfang said that he has performed low-energy laser treatment on more than a dozen patients with alopecia areata. Compared with the traditional treatment that requires six to eight weeks, the hair will not continue to fall out. This new treatment only takes one month to see the effect. , which is equivalent to shortening one-third of the course of treatment.
Liao Yihua, a dermatologist at National Taiwan University Hospital, also tried to use near-infrared rays to promote wound healing. She pointed out that at present, whether it is local ulceration of the lower extremities caused by diabetes or chronic ulcers caused by arterial and venous obstruction (such as varicose veins), only conservative treatments such as coating and bandaging can be used, but near infrared rays use photobiostimulation effects. It can increase skin keratinocytes and collagen, improve skin microcirculation, and promote wound healing. Each irradiation takes about three to five minutes, and only one or two times can make deep wounds that have not healed for a long time to shrink the wound. Effect.
