  • A noncoherent, broadband, intense pulsed light source has been used for the symptoms of photoaging skin as a nonablative method. The purpose of this study is to investigate the efficacy and tolerability of intense pulsed light in solar lentigines and ephelides on the face. An open study was performed in patients with solar lentigines and ephelides who received three to five treatments of intense pulsed light. Forty-eight percent of patients had more than 50% improvement and 20% had more than 75% improvement. In the group of solar lentigines, 40% of patients showed more than 50% improvement and 16% did more than 75% improvement. Patients with solar 1entigines+ephelides and ephelides responded remarkably with 75% and 71 % of patients having more than 50% improvement, respectively. Intense pulsed light was well tolerated and may be a new modality for the therapy of solar lentigines and ephelides.

  • Intense pulsed light(IPL) is a photo-therapeutic medical device using xenon lamps with optical characteristics of incoherence, defocusing, and polychromatic. IPL has been recognized as a representative medical therapeutic device with growth of domestic skin care market. However, there is no standard regulation manual and guideline to evaluate the safety and performance of IPL. International Electrotechnical Commission(IEC) is being statued "Technical Report IEC TR 60825-16" which is a guidelines for the safe use of intense light source equipment on humans and animals. In this study, a standard Korea Food & Drug Administration (KFDA) regulation for the safety and performance of IPL was suggested by developing minimal evaluation methods for optical parameters of IPL such as output energy density, pulse mode, spot size, wavelength and uniformity of output light. We expect that this study may be a step to statue a standard regulation manual and guideline for IPLs used in domestic.

  • Objectives : The purpose of this study is to compare the principles between moxibustion and the 'Intense pulsed light (IPL)' and to investigate the clinical application of the photo-moxa for the Korean medicine fields. Methods : The characteristics of moxibustion, IPL, parabolic reflector moxa and the dermatology surgical use of moxibustion were reviewed in the literature. Results : IPL is one type of light treatments that is employed by radiating the short-pulse wave, which is transformed from the light of high intensity. There has been used parabolic reflector in Asia for more than 2,000 years, and this hand-held device used for moxibustion in traditional medicine. Moxibustion is one of the treatment tools in Korean medicine using the heat energy. The fluence or energy density of IPL in clinical circumstances is similar to parabolic reflector moxa of moxibustion. IPL and parabolic reflector moxa shared same treatment principle employing the heat energy. Therefore IPL could apply for many indications in Korean medicine as a moxibustion tool and acupuncture. Conclusions: IPL may be plausible to be a fascinate method in phototherapy of Korean medicine.

  • Objectives The purpose of this study was to report the effects of Korean medical treatment (acupuncture, moxibustion, herb medicine) combined with intense pulsed light (IPL) on three postpartum patients with freckles worsened during pregnancy. Methods and Results The postpartum patients with freckles were treated with acupuncture, moxibustion, herbal medication and IPL. The energy density of IPL was selected modified according to skin types classified by Sasang constitutional medicine. This efficacy of treatment was evaluated with observation. After treatment, freckles as well as various postpartum symptoms are improved. Conclusions This case report shows that the Korean medical treatment combined with IPL is effective in the treatment of postpartum patient's freckles. However further studies are still necessary.

  • The objective of this study was to investigate the feasibility of applying the Intense Pulsed Light (IPL) as a tool to enhance the skin absorption of arbutin, a well-known skin-whitening agent. Arbutin solution or skin formulation was applied on the back of hairless mouse skin in vivo after IPL treatment, and then the skin deposition of arbutin was determined by HPLC. IPL treatment significantly increased the amount of arbutin in the skin after 6 hours when arbutin solution was applied 20 times. IPL also enhanced the skin deposition of arbutin when arbutin formulation was applied, although it was not significantly different. Significant increase of surface skin temperature was observed by IPL treatment, which might be a mechanism of the enhanced skin absorption of arbutin. These results suggest the feasibility of using IPL as a tool to increase the skin absorption of whitening agents, although further research needs to be conducted to understand its exact mechanism.

  • Intense pulsed light(IPL) has been highlighted as an innovative nonthermal sterilization technology that can kill spoilage or pathogenic microorganisms by using short-duration pulses of intense broad-spectrum electromagnetic radiation. This paper examines the inactivation effects of IPL on Listeria monocytogenes, Escherichia coli O157:H7, and Pseudomonas aeruginosa inoculated on seafood products such as salmon, flatfish, and shrimps and evaluates the possibility of extending the shelf-life of seafood products. The results indicate that the inactivation of microorganisms increased with an increase in IPL energy density($J/cm^2$) and a decrease in the distance between the sample surface and the lamp. In addition, temperature increases on the fish fillets during the treatments were well controlled within the range of 5.7~$9.8^{\circ}C$. The IPL treatment had a significant positive effect on the storage stability of seafood products at the storage temperature of $4^{\circ}C$ for 12 days. These results suggest that the storage period for fish fillets can be extended from 4 days to 6~8 days through the IPL treatment.

  • The consumption of meat has been increasing, leading to a dynamic meat and meat processing industry. To maintain the quality and safety of meat products, various technologies have been explored, including intense pulsed light (IPL) technology. Several factors affect the inactivation of microorganisms by IPL treatment, including light intensity (fluence), treatment duration, pulse frequency, and the distance between the lamp and the samples. Meat products have been studied for IPL treatment, resulting in microbial reductions of approximately 0.4-2.4 Log. There are also impacts on color, sensory attributes, and physico-chemical quality, depending on treatment conditions. Processed meat products like sausages and ham have shown microbial reductions of around 0.1-4 Log with IPL treatment. IPL treatment has minimal impact on color and lipid oxidation in these products. Egg products and dairy items can also benefit from IPL treatment, achieving microbial reductions of around 1-7.8 Log. The effect on product quality varies depending on the treatment conditions. IPL technology has shown promise in enhancing the safety and quality of various food products, including meat, processed meat, egg products, and dairy items. However, the research results on animal-based food are not diverse and fragmentary, this study discusses the future research direction and industrial application through a review of these researches.
