“…Importantly, four patients (19%) in the laser‐treated group had postinflammatory hyperpigmentation (PIH), with FPTs IV and V (Figure 7), whereas the univariate correlation analysis revealed significant factors for the development of PIH after laser treatment, 13 including FPTs IV‐V, duration of melasma, previous melasma treatment with laser or light therapy, and knowledge of sunscreen usage. Moreover, the mean duration of melasma in the PIH group was 12 ± 6.27 years, compared to the non‐PIH group of 4.71 ± 4.47 years, with statistically significant difference ( P = .013).…”

“…Moreover, the initial efficacy and the recurrence of melasma were commonly observed after several treatments, 27 such as 1064‐nm QSNYL for melasma with the 12‐week follow‐up after last laser session, which yielded the partial recurrence of melasma in all cases 16 .

Background:The potential efficacy of vascular component-targeted laser has been evaluated for the treatment of melasma, which commonly found with the co-existence of telangiectasia. Aims:To evaluate the treatment efficacy and safety of 585-nm QSNYL and 4% HQ cream combination vs 4% HQ cream alone for telangiectatic melasma in the skin phototypes III-V.Patients/Methods: Twenty-one Thai female patients with telangiectatic melasma and Fitzpatrick skin phototypes (FPTs) III-V were randomly treated with the 585-nm QSNYL on one side of the face for five sessions at 2-week intervals. All patients were assigned to apply HQ cream daily at night on both sides of the face for 10 weeks and a broad-spectrum sunscreen regularly throughout the study. The treatment efficacy and safety were evaluated using the Modified Melasma Area and Severity Index (mMASI), biometric evaluation, patient assessment, and adverse effects. Results:The combination-treated side yielded more significant improvement of mMASI than the topical-treated side at weeks 2, 4, and 8, respectively. However, 19% of the patients developed postinflammatory hyperpigmentation (PIH) on the laser-treated side, especially in FPTs IV-V and rebound hyperpigmentation. There was a significant improvement of hemoglobin and melanin index, but without statistical difference between the two treatment groups. Conclusions:The combination of 585-nm QSNYL and HQ treatment yields treatment efficacy and skin rejuvenation effects for telangiectatic melasma. Nonetheless, a high incidence of PIH and rebound hyperpigmentation is adversely developed in dark FPT. Thus, this laser treatment should be cautiously applied in those with dark FPTs IV-V to avoid laser-induced pigment alteration.

Introduction Prolonged sun exposure has been linked with the development of numerous medical and dermatological complications, such as skin cancer. Photoprotection can help reduce ultraviolet radiation (UVR)-induced skin damage and skin cancer. This study aims to assess the knowledge about and attitude toward the use of sun protection to prevent laser adverse events among the general population in Saudi Arabia. Methodology This is a cross-sectional, analytical, community-based study carried out among the general population (sunscreen users) in Saudi Arabia. A total of 600 participants were enrolled in the study. Data were collected using a validated online self-administered questionnaire using Google Forms. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0 (IBM Corp., Armonk, NY). Results A total of 600 sunscreen users were enrolled in this study, with an overall poor knowledge rate of 471 (78.5%) regarding the use of sun protection methods. Their ages ranged from 18 years to >55 years. The majority of them were females (537, 89.5%), had Saudi Nationality (533, 88.8%), and had skin type III (313, 52.2%). Almost all the participants (491, 81.9%) had undergone laser treatment before; the most reported reason was hair removal (522, 87%). In addition, 267 (44.5%) participants used sunscreens five to six times a week, with 440 (73.3%) also using sunglasses. Notably, only 91 (15.2%) of the study participants were aware that sunscreen covers UVA and UVB, and 34 (5.7%) knew that PA+++ is used in sunscreen. A total of 149 (24.8%) reported that sunscreen should be applied 20 to 30 minutes before sun exposure, while 153 (25.5%) stated that it should be reapplied every two hours. Moreover, 484 (80.7%) participants reported using topical steroid application after laser treatment. The results also showed that young participants ( P = 0.001), single participants ( P = 0.001), post-graduate participants ( P = 0.010), students rather than the unemployed group ( P = 0.002), and those who used sunscreens five to six times per week compared to those who never used sunscreens ( P = 0.001) demonstrated an overall good knowledge about sunscreens and laser treatment. Conclusions The study showed poor knowledge among the participants regarding the use of sun protection to prevent adverse laser events. Therefore, an increase in awareness among the general public about the protection through campaigns is highly recommended.
