Concept: Intense pulsed light
Abstract Background: Recently, tranexamic acid (TNA) containing oral medication has gained public attention, claiming for whitening effects. Objective: This study was performed to evaluate the clinical efficacy and safety of oral TNA as an adjuvant to intense pulsed light (IPL) and laser treatment in melasma. Methods: A total of 51 patients were included in the study. Patients who have been on oral TNA during IPL and laser treatments (group A) and those who were treated with only IPL and laser (group B) were analyzed (from winter to summer). Modified melasma area and severity index (mMASI) scores were blindly evaluated by two investigators using digital photographs taken at each visit. Results: The mean modified MASI score decreased from 11.33 ± 7.07 to 6.21 ± 5.04 in group A and from 11.70 ± 6.72 to 8.93 ± 5.89 in group B (baseline vs. 2 weeks after the last treatment, p = 0.005). Modified MASI score right before and after IPL were more reduced in group A. No serious adverse effects were reported up to 8 months of oral TNA medication. Conclusion: Oral TNA may improve clinical efficacy in light- or laser-based melasma treatment especially during the period of relative high sun exposure without serious adverse effects.

BACKGROUND: Unwanted hair growth is a common aesthetic problem. Laser hair removal has emerged as a leading treatment option for long-term depilation. OBJECTIVES: To extensively review the literature on laser hair removal pertaining to its theoretical basis, current laser and light-based devices, and their complications. Special treatment recommendations for darker skin types were considered. MATERIALS AND METHODS: A comprehensive literature search related to the long-pulse alexandrite (755 nm), long-pulse diode (810 nm), long-pulse neodymium-doped yttrium aluminum garnet (Nd:YAG; 1,064 nm), and intense pulsed light (IPL) system, as well as newer home-use devices, was conducted. RESULTS: The literature supports the use of the alexandrite, diode, Nd:YAG and IPL devices for long-term hair removal. Because of its longer wavelength, the Nd:YAG is the best laser system to use for pigmented skin. Further research is needed regarding the safety and efficacy of home-use devices. CONCLUSION: Current in-office laser hair removal devices effectively provide a durable solution for unwanted hair removal.
The purpose of our study was to verify the results of the association of Q-switched Nd: YAG non-ablative fractionated with intense pulsed light, in order to treat patients with refractory melasma. The combination of these two devices seems to be the best treatment to combat hyperpigmentation produced by melasma, with low occurrence of side effects, which may be justified by the selective photothermolysis at subcellular level.
To investigate the change from baseline of inflammatory markers in tears of dry eye disease(DED) subjects due to meibomian gland dysfunction(MGD) after IPL(intense pulsed light) treatment and meibomian gland expression(MGE) compared to sham treatment, and the correlations with ocular surface parameters.
The development and use of light and lasers for medical and cosmetic procedures has increased exponentially over the past decade. This review article focuses on the incidence of reported cases of skin cancer post laser or IPL treatment. The existing evidence base of over 25 years of laser and IPL use to date has not raised any concerns regarding its long-term safety with only a few anecdotal cases of melanoma post treatment over two decades of use; therefore, there is no evidence to suggest that there is a credible cancer risk. Although laser and IPL technology has not been known to cause skin cancer, this does not mean that laser and IPL therapies are without long-term risks. Light therapies and lasers to treat existing lesions and CO2 laser resurfacing can be a preventative measure against BCC and SCC tumour formation by removing photo-damaged keratinocytes and encouraged re-epithelisation from stem cells located deeper in the epidermis. A review of the relevant literature has been performed to address the issue of long-term IPL safety, focussing on DNA damage, oxidative stress induction and the impact of adverse events.
HS is a debilitating chronic skin disease of the hair follicle. Intense pulsed light therapy has been suggested for treatment of HS. In this letter we report a retrospective chart review of the Hidradenitis Suppurativa patients we have treated so far.
Cutis Marmorata Telangiectatica Congenita successfully treated with Intense pulsed light therapy - A case report

Cutis marmorata telangiectatica congenita is a rare disorder characterized by cutis marmorata, telangiectasia with or without recurrent ulcerations. It is a benign vascular anomaly with dilatation of capillaries and veins in the dermis. There is no satisfactory treatment for the ulcerative variety of cutis marmorata telangiectatica congenita. In this case intense pulse light therapy was used with almost near total cure.intense pulse light with its' vascular filter of wavelength 550-1200 nm was used every fortnight till complete resolution of lesions.
Lasers and noncoherent intense pulse light sources effectively treat vascular lesions. Intense pulsed light (IPL), a nonablative treatment for photorejuvenation, uses a flashlamp which emits noncoherent light between 400 and 1400 nm. The light may be filtered to target a specific chromophore. The pulsed dye laser (PDL), at 595 nm, has been the historical standard of care in the treatment of facial erythema. We sought to determine whether IPL may be used in lieu of PDL in reducing facial erythema.
Although ear reconstruction technology has been highly developed in recent years, hair growth on the reconstructed ear has plagued both surgeons and patients. In this paper, the authors introduce a clinical application of intense pulsed light depilation in total auricular reconstruction. From August 2012 to August 2013, 27 patients (28 ears) suffering from congenital microtia were treated by intense pulsed light depilation (650-950-nm filter, initial fluence of 14-16 J/cm(2) and gradually increased, pulse width of 30-50 ms, spot size of 20 × 30 mm(2), intervals of 6-8 weeks, a total of four sessions) either before or after auricular reconstruction. According to the treatment situation at diagnosis, the patients were divided into two groups: the preoperative group and the postoperative group. There were no differences between the two groups in terms of age or initial fluence for hair removal; however, there were less treatments in the former than in the latter group (preoperative group 4.1 ± 0.3, postoperative group 4.7 ± 0.7, F = 9.10, P = 0.006), and the maximum fluence used for hair removal was lower in the former than in the latter group (preoperative group 18-20 J/cm(2), postoperative group 19-22 J/cm(2), F = 22.31, P < 0.001). After follow-up for ≥4-6 months, the effective rate was 100% in the preoperative group, and the effective rate was 80% in the postoperative group. Intense pulsed light depilation technology is a reasonable complementary approach to total auricular reconstruction. And preoperative depilation is recommended over postoperative depilation. The non-invasive modern photonic technology can resolve the problem of postoperative residual hair on the reconstructed auricle, improving auricular shape and increasing patient satisfaction. In addition, an adequately set preoperative hair removal area can provide surface skin that is most similar to normal auricle skin for auricular reconstruction.
Different treatment modalities are used for the treatment and esthetic improvement of aging hands. This study evaluated the efficacy and safety of a novel technology, which combines bipolar radio frequency (RF) and optical energies for the cosmetic treatment of aging hands. The objective of the study was to assess the efficacy, safety, tolerability, and patient satisfaction of combined bipolar radiofrequency and optical energies vs. optical energy alone for the treatment of aging hands. Thirteen female patients with solar lentigines on the back of the hands were enrolled. Participants received three treatments: combined RF and intense pulsed light (IPL) on one hand and IPL treatment alone on the other. Standardized clinical photographs were taken, and patient and investigator improvement assessment (Global Esthetic Improvement (GAI) scale), patient satisfaction, and tolerability were evaluated. At the 1 and 3 months follow-up, skin laxity and pigmentation, investigator and patient improvement assessments, and satisfaction were significantly better in the hand treated with combined bipolar RF and IPL. This study demonstrates the safety and efficacy of combining RF and optical energies for the esthetic improvement of aging hands. Combined RF and IPL treatment was more efficient than IPL alone in improving skin pigmentation, skin laxity, and texture.
