Introduction: Laser hair removal (LHR) has become one of the most popular treatments in aesthetics. Side effects are an inevitable part of laser therapy, therefore managing them is crucial for every laser practitioner to ensure patients’ safety along with achieving the best results. The available references describe the effectiveness of the diode LHR for all skin types according to the Fitzpatrick scale, but the question of patient safety and minimization of side effects and postoperative complications in mixed-race patients remains unanswered. This study aims to illustrate aspects of specific side effects in patients of mixed ethnicity and the impact of those effects on the results of the treatment. Methods: The study was conducted in Poland and the United Kingdom on 216 patients of various ethnic backgrounds. This study analyses the frequency of side effects in a mixed-race group of 32 participants, taking into account their skin type according to the Fitzpatrick scale. The patients received a course of 6 treatments using diode laser 805 nm. An objective and a subjective method were used to analyse treatment results and side effects, with adverse effects documented, if observed. Treatment settings were adjusted to skin reaction during the patch test. Results: Objective analysis was different from the subjective analysis of the treatment’s effectiveness. No adverse effects were observed. Side effects such as hyperpigmentation, skin irritation, skin burns, and skin hypersensitivity were found. Conclusion: 805 nm diode laser is effective and efficient at hair removal in mixed-race patients. It is a safe treatment in terms of skin reaction as only short-term side effects were observed in the treated area and no adverse effects were noted. To achieve the best results and to avoid adverse effects it is necessary to adjust treatment settings according to the individual patient’s skin reaction.

Introduction: Laser hair removal needs an accurate understanding of tissue structure and chromophores content in order to optimize the selection of laser irradiation parameters. None of the optimized laser therapy might lead to side effects in skin tissue such as severe erythema, burn, scar etc. Therefore, guidance by a noninvasive real-time diagnostic method like optical spectroscopy technique is beneficial. The purpose of this survey is to analysis the skin hemoglobin spectrum quantitatively before and after hair removal laser irradiation to minimize the side effects of the procedure. Methods: To carry out a spectroscopy study, a halogen-tungsten light source was used in the wavelength region of 400-700 nm on an ocean optic device. The measurements were made on the facial area under identical conditions. Total 19 volunteers for laser hair removal by gentle laser Candela, ranging 14- 49 years old, were included in the study. A total of 18 spectra were taken from each person, 9 spectra before hair removal as a reference and 9 subsequent spectra. Colorimetry was done for all acquired before and after spectrums using Origin software (version 8.6). Then, the erythema index derived for each spectrum. Statistical analysis of correlation and normalization in colorimetry data were done using data analysis by SPSS (version 16). Results: Spectra analysis, before and after optical reflectance spectrums in laser hair removal procedure, revealed the subpeak derivation, and concentration on special visible wavelength 510- 610 nm. We studied the changes of skin chromophores absorption. The derived erythema index [E] and colorimetry parameters a*, b*, l* were compared and correlated statistically. There was a statistically considerable direct linear correlation between a* and E while inverse linear correlation was observed for l* and E and no correlation for b* and E. Conclusion: Diffuse reflectance spectroscopy showed its potency as an accurate, noninvasive realtime as complementary method for laser treatment to detect erythema as a complication of the method, in order to optimize the parameters based on the tissue characteristics in various candidates.

The Impact

Introduction: As hair removal has become most popular in aesthetics, the management of its side effects is crucial for every practitioner. Available studies describe the effectiveness of the diode laser hair removal for all skin types according to the Fitzpatrick scale independently, but the question of the occurrence of side effects and adverse effects remains unanswered. This study aims to illustrate aspects of side effects for patients of various ethnicities and the impact of those on the effectiveness of the treatment. Methods: The research was carried out in Poland and the United Kingdom from March 2016 to March 2019. 217 people of various ethnic origins were qualified for the study, 206 sessions were completed and statistical analysis was performed. The procedure was performed in the pubic area with diode lasers with a wavelength of 805 nm, minimum peak power of 2100 W and pulse duration between 15 and 400 ms. ET sapphire cooling assisted handle 9 x 9 mm large and pulse energy density between 10 and 100 J/cm2 were used for all treatments. In addition, in order to illustrate the effectiveness of treatments, the subjective and objective analyses of hair loss percentages were indicated. In statistical analysis, the chi-square test for independence was used to evaluate the correlation between the type and severity of side effects and the ethnic origin of patients, the number of treatments, the Fitzpatrick scale and the level of satisfaction. Results: The occurrence of sensitivity depended statistically significantly (P=0.002) on ethnicity. Ethnicity had no significant effect on the occurrence of erythema. The occurrence of hyperpigmentation statistically significantly depended (P<0.001) on ethnicity. The occurrence of burns depended statistically significantly (P=0.001) on ethnicity. The number of treatments had a significant (P=0.012) effect on the severity of side effects occurrence. Among participants who had 6 treatments, only half had side effects, including multiple effects occurring in 9.79% of cases. The occurrence of side effects such as sensitivity and hyperpigmentation did not depend on the number of treatments. However, the number of treatments had a significant impact on the incidence of erythema (P<0.001) and burns (P=0.005). More than half of the respondents (58.33%) had erythema after more than six procedures, whereas in the 6 treatments the erythema occurred only in 6.7% of cases. Conclusion: The treatment with the use of diode lasers for all subjects with different ethnicity and thus the recognized scale according to Fitzpatrick is effective and safe. The occurring side effects are transient and do not impact the effect of the whole therapy.
