The LASER PULSE consortium has developed a Guiding Questions Workbook to provide a concise process to develop a research translation strategy and plan for evidence utilization in international development. Academic researchers, development practitioners, and donors can use this workbook to strategize and plan for research impact.
LASER PULSE, which stands for Long-term Assistance and SErvices for Research (LASER) Partners for University-Led Solutions Engine (PULSE), is a $70 million cooperative agreement with USAID led by Purdue University with partners University of Notre Dame, Makerere University, Catholic Relief Services and IU.
A recent LASER Focused webinar introduced the resource and gave practical examples for how the workbook could be used to improve research translation. Additionally, two representatives from the LASER PULSE consortium attended the 2022 Social Behavior Change Communication (SBCC) Summit in Morocco to promote the LASER PULSE program and launch the new workbook.

It also provides explanations of the science behind laser technology and suggestions for further experimentation.
Use of the laser cutter and engraver is free. If you bring your own material to cut or engrave you must provide a receipt or tag that states what the item is made of. Material approval is up to the discretion of the MakerSpace staff. It is highly recommended that you bring extra material for testing. We have acrylic and wood plaques available for purchase. A staff member is required to prepare the machine for you.

The demand for safe, long-lasting, and effective hair reduction for aesthetic as well as medical indications is on the rise. A variety of options for hair removal are available, such as epilation by plucking or waxing, depilation by shaving, chemical depilatories, electrolysis, eflornithine cream, and laser and intense pulsed light (IPL) systems. A variety of lasers and IPL systems are available and are the best option for long-term hair reduction. This activity describes the different lasers, their indications, contraindications and complications and highlights the role of the interprofessional team in educating patients who want to undergo hair removal.
Objectives:
- Describe the different lasers used for hair removal.Review the indications for laser hair removal.Summarize the complications of laser hair removal.Outline interprofessional team strategies for improving care coordination and communication to advance care bundle approaches for hair removal with the laser and improving outcomes.
The demand for safe, long-lasting, and effective hair reduction for aesthetic as well as medical indications is on the rise. A variety of options for hair removal are available, such as epilation by plucking or waxing, depilation by shaving, chemical depilatories, electrolysis, eflornithine cream, and laser and intense pulsed light (IPL) systems. A variety of lasers and IPL systems are available and are the most effective options for long-term hair reduction.[1] The mechanism of action of these systems is the targeting melanin in the hair shaft, follicular epithelium, and hair matrix by emitting light with wavelengths ranging from 600 to 1200 nanometers (nm), because those wavelengths are selectively absorbed by melanin.[2]
Lasers for skin treatment work on the theory of "selective photothermolysis." This term implies a site-specific, thermally mediated injury of microscopic tissue targets by the selective absorption of pulses of radiation by the targets and the chromophores. The natural or artificial chromophores absorb monochromatic or broadband electromagnetic radiation of specific wavelengths. The chromophore employed in laser hair reduction is melanin. Melanin absorbs light in the range of 300 to 1200 nm, and lasers in this range of wavelengths can be effectively used for hair reduction.[3][4]
Target absorption may not always be uniform. In these cases, the weakly absorbing parts may have to be destroyed by heat diffusion from the highly absorbing parts. This is the "extended theory of selective photothermolysis." This principle is applied to laser photoablation. Melanin content is much higher in melanin-bearing structures like the hair shaft and matrix cells than in the hair follicle. Thus melanin captures energy from the laser and distributes it to the surrounding follicular structures. This results in the destruction of the hair matrix and hair bulge stem cells.[5]
The hair matrix is only sensitive to laser treatment during the anagen phase of the hair growth cycle; therefore multiple treatments will be necessary in order to address all hair follicles when they are most sensitive to treatment. In the initial phase of hair removal therapy, 4 to 6 sessions spaced 4 to 6 weeks apart are the minimum required to achieve adequate results. Subsequently, patients may need maintenance treatments once every 6 to 12 months as small vellus hair may grow back.[16]
Adjacent epidermal structures other than melanin within the hair bulb can compete for absorption, and may cause laser energy to be absorbed by pigment in the epidermis. This hampers the effectiveness of the treatment and causes adverse effects due to adjacent epithelial damage. [17]
More severe adverse effects include blistering, crusting, dyspigmentation, purpura, and sometimes scarring.[19][20] Ocular complications due to accidental injury may be seen. Paradoxical hypertrichosis may rarely occur, more commonly in skin type III and with the use of IPL systems.[21][22][23]
Selecting the correct lasers with the appropriate parameters, individualized to each patient, is very important, particularly in patients with intrinsically dark skin. Most complications are preventable when adequate precautions are taken with adjustment of the fluence, spot size, wavelength, and the use of appropriate cooling. Thus, it is all the more important that trained personnel with a thorough knowledge of the mechanisms, techniques, and complications carry out these procedures.
Laser hair removal is performed by many healthcare workers including nurses, dermatologists, plastic surgeons, primary care providers and other cosmetic surgeons. Unfortunately, because of lack of oversight, complications are common during this procedure. To make matters worse, patients are often given unrealistic expectations. The key is to use the correct laser, especially in dark skinned individuals. Common adverse effects of laser or IPL-based hair removal include post-treatment erythema, pain, and burning.[18] More severe adverse effects include blistering, crusting, dyspigmentation, purpura, and sometimes, scarring.[19][20] Ocular complications due to accidental injury may be seen. Paradoxical hypertrichosis may rarely occur, more commonly in skin type III and with the use of IPL systems.[21][22][23]
