Clinical Evaluation of a Novel Blended Mode Diode Laser for Hair Removal

Laser hair removal is a medical procedure that uses a concentrated beam of light (laser) to remove unwanted hair. Numerous published clinical studies have demonstrated the safety and efficacy of different lasers at various wavelengths for hair removal. The three commonly used hair removal lasers are of specific wavelengths: 755 nm, 810 nm, and 1064 nm, each preferred certain types of skin and hair characteristics.

The current evaluation reported the safety and efficacy of unique blended modes 755/810 nm and 810/1064 nm diode lasers for hair removal. Results from 50 subjects (44 females, 6 males) treated with the 755/810 nm handpiece and 50 subjects (50 females) who were treated with the 810/1064 nm handpiece were accumulated from a few clinics in the USA, Canada, France, and Israel during 2018. Subjects underwent 3 treatment sessions 6 weeks apart and were followed up with 6 months post their last treatment. The study efficacy was assessed by average hair reduction at the 6 month follow-up visit compared to the baseline count. Hair counts were performed on photographs taken from the subjects’ treatment areas. Subjects consented to use of their photographs. Safety of the device was evaluated by assessing the incidence, severity and persistence of adverse events, if any occurred during the study period.

Treatment area photos demonstrated hair reduction in the treated body and facial areas. Average hair count reduction at 6 months follow-up was 84% for the 755/810 nm handpiece and 81% for the 810/1064 nm handpiece. No significant or unexpected adverse events were detected in any of the patients. 

In short, the novel blended mode hair removal diode lasers are proven to be safe and effective for hair removal in facial and body areas for patients of various skin types and hair characteristics. More studies are planned to further substantiate the potential clinical contribution of the newly developed blended wavelengths concept.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
