the desire to achieve cosmetic rejuvenation and reduce effects of aging and photodamage urged scientists to develop effectual techniques which have minimal side effects and impressive long-term efficacy. traditional ablative resurfacing laser therapy has been used for several years;however, it has harmful side effects on the patient’s skin such as dyspigmentation, persistent erythema, infection...

Background: Hirsutism is defined as the presence of terminalhairs with a male-like pattern in women, due to the increasedlevels of androgens or increased responses of the target organs toandrogens. Facial hirsutism has a negative effect on the quality oflife in female patients. Among the many therapeutic modalitie...

Rhinophyma is a benign and disfiguring tumor of the nose, affecting white old men. It represents the end stage of acne rosacea. Hypertrophy of the sebaceous apparatus and fibrosis lead to an enlarged, erythematous nasal tip with comedones. Treatment modalities include Isotretinoin (Which is not effective on severe rhinophyma), freehand scalpel shave, cryosurgery, electrocautery, dermabras...

introduction: myofascial pain syndrome (mps) treatment is challenging with a high recurrence rate and still lacks a clear treatment frame. therefore research on new, more efficient and long lasting effect treatment modalities is necessary. this study looked at the effects of intravenous laser therapy (ivl) and percutaneous low level laser (plll) in the management of shoulder mps. methods: in th...

introduction:  carpal tunnel syndrome (cts) is the most common compressive neuropathy. several surgical and nonsurgical treatments have been proposed for this syndrome, but there is no consensus regarding the prioritization of the suggested nonsurgical treatments. the goal of this study was to compare the long term effects of laser therapy versus local corticosteroid injection in the treatment ...

introduction: photobiostimulation with low level laser (lll) has been used in medicine for a long time and its effects have been shown in many diseases. some studies have evaluated the effect of lll on androgenic alopecia. one of the most important limitations of the use of lll in the treatment of alopecia is the requirement for multiple sessions, which is hardly accepted by patients. this stud...

introduction: laser phototherapy is used for the treatment of chemotherapy-induced oral mucositis in patients with leukemia, although there are limited data supporting the safety of this method. this study aimed to evaluate the effect of different doses of low-level laser on proliferation of acute myeloid leukemia (aml) cell line (kg-1a) in vitro. methods: a plastic flask containing 5,000,000 k...

introduction: carpal tunnel syndrome (cts) is the most common type of entrapment neuropathy. conservative therapy is usually considered as the first step in the management of cts. low level laser therapy (lllt) is among the new physical modalities, which has shown therapeutic effects in cts. the aim of the present study was to compare the effects of applying laser and splinting together with sp...

introduction: the aim of the present study was to evaluate the effect of photodynamic therapy in the treatment of experimental corneal neovascularization (nv) with benzoporphyrin derivative (bpd). methods: one group was considered as control (n=6 eyes) then, corneal nv was induced in 30 new zealand male rabbits (n=60 eyes) by placing 7.0 silk sutures at midstromal depth approximately1mm from th...

it is the output power and density of the lasers which determine whether a laser is a low or high-power one. if the density is less than 670mw/cm2, the laser is called a low power one. the output power of these lasers is usually less than 250mw. they use different mechanisms to accelerate wound healing such as: cellular biostimulation, improvement of circulation, vasodilation, analgesic and ant...
