“…The mechanisms underlying reduced skin pigmentation related to LVS treatment require further investigation, but are likely due (at least in part) to the protection from blue light (e.g., high‐energy visible light) afforded by Theobroma cacao seed extract. Blue light irradiation of skin can cause the formation of reactive oxygen species and has been shown to induce pigmentation in Fitzpatrick skin types III–VI, 24,27‐30 which is in keeping with the published characteristics of Chinese skin of Fitzpatrick types III and IV 31,32 …”

Background Chronic exposure to air pollution can negatively affect skin health. Aims To assess the efficacy of the LUMIVIVE® System (LVS), a skincare system consisting of individual day and night serums, in Chinese women exposed to air pollution. Patients/Methods In this single‐center, vehicle‐controlled study, eligible females (mean age, 49.02 years) were randomized 1:1 to treatment group (LVS plus basic moisturizer) or control group (basic moisturizer). Skin color, sebum content, barrier function, elasticity, and texture were measured at baseline and at each follow‐up visit (days 28, 56, and 84). Air pollution parameters were collected throughout the study. Results Air pollution levels, including PM2.5 and NO2, were consistently high during the study. The treatment group showed significantly higher skin color L* (p ≤ 0.0001) and lower a* values (p ≤ 0.05) at all follow‐up visits compared with the control group, indicating lower skin pigmentation and redness, respectively. Skin color L* and a* values remained unchanged over time for the control group but were significantly different at all follow‐up visits compared to baseline (p ≤ 0.0001 and p ≤ 0.05, respectively) for the treatment group. There was an increasing trend for sebum content in the control group, which was not observed in the treatment group. Both groups showed improvements over time in other skin physiology parameters. Conclusions The current analysis demonstrates the efficacy of LVS plus basic moisturizer compared with basic moisturizer alone to reduce skin pigmentation and redness, as well as to mitigate sebum production, in Chinese women exposed to air pollution.

“…The effect any UV exposure could cause to fair skin in 15 min could take up to hours for people with darker skin because of melanin (which is responsible for skin darkness) absorbing the UV radiation [ 3 , 31 ]. In this regard, the South Asian population has generally dark skin complexion belonging to skin-type IV and V according to the Fitzpatrick complexion scale [ 32 , 33 ]. This most likely explains Bangladesh ranking 183rd globally on the list for the prevalence of melanoma [ 34 ], and also sunburn is extremely rarely reported in this region.…”

“…This means UV-B intensity remains very low during this time, which starts getting more intense as it approaches mid-day. Along with this, taking the generally dark complexion of the Bangladeshi population (skin types IV and V) [ 32 , 33 ], net absorption of UV-B (even after direct exposure) by an average Bangladeshi in the morning would likely be really low. However, this scenario would change around mid-day time (10 am to 3 pm) when the level of UV-B in the sunlight would be maximum.…”

Risk perception of sun exposure and knowledge of vitamin D among the healthcare providers in a high-risk country: a cross-sectional study

et al. 2023

Background High levels of vitamin D deficiency are commonly reported even in regions with abundant sunshine. This necessitates a comprehensive understanding of the determinants that influence sun exposure practices. As the primary source of health-related knowledge for the general public, the attitude of the healthcare professionals towards sunlight and their awareness related to vitamin D deficiency can be critical in this regard. Methods A cross-sectional survey was conducted among 2,242 physicians, intern doctors, and senior medical students in Bangladesh from October 2019 to February 2020. A pre-tested structured questionnaire (containing twelve close-ended questions) was used. The perceptions of health risks due to sun exposure, and basic knowledge of the physiological and epidemiological aspects of vitamin D deficiency were tested. Results An overall negative attitude towards sunlight in the context of Bangladesh was highlighted – 68% participants thought regular sun exposure would be harmful or very harmful; 26% thought the level of UV radiation was very high; 44% recommended using sunscreen always; skin burns, heat stroke, and cancer were selected as potential consequences of regular sun exposure by 45%, 21%, and 30% respondents respectively. Overall knowledge regarding vitamin D deficiency appeared to be biased towards bone health; other symptoms and associated illnesses not having obvious link to Calcium-metabolism were identified much lesser frequently. Furthermore, ‘sunrise to 10 am’ was identified as the best time to get vitamin D by 69% participants; 60% believed < 30 min of weekly sun exposure would be sufficient for the Bangladeshi population; an only 33% identified that prevalence of vitamin D insufficiency in Bangladesh would be 50% or more. Taking vitamin D-rich food was suggested by more respondents over regular sun exposure (43% vs. 33%) as more effective remedial strategy to curb vitamin D deficiency in Bangladesh. Conclusion In addition to highlighting some crucial knowledge gaps, results from this study provides a comprehensive baseline dataset for knowledge and attitude regarding the public health aspects of vitamin D deficiency among the healthcare providers in Bangladesh, which would be generalizable to other countries with similar socio-demographic context, and will facilitate taking more effective policies worldwide.

“… 15 This result is in accordance with references stating that most people with skin of color (Fitzpatrick skin type III and IV) living in coastal area tend to have earlier and more rapid pigmentation changes (dyschromia) since the most common forms of photoaging in skin of color are lentigo and mottled pigmentation. 18 , 19 …”

Purpose Repeated exposure to ultraviolet light is the most significant factor that contributes to photoaging. Dermoscopy photoaging scale (DPAS) is a noninvasive examination utilized for the diagnosis of photoaging. However, there has been no study analyzing the correlation between DPAS and sun index. Hence, this study aims to find out the dermoscopic features of photoaging and its association with sun index score in the coastal population. Patients and Methods This was a descriptive cross-sectional study on individuals living in Cilincing, a coastal area, at North Jakarta. Healthy male or female subjects aged over 18 years old with sun exposure equal or more than 2 hours daily were recruited consecutively. History taking was performed to document the sociodemographic characteristics (age, gender, skin type, smoking habit) and sun index score. Physical examination and dermoscopic examination were conducted to determine DPAS score. Associations of DPAS and photoaging profiles were analyzed with Chi-squared test while correlation between DPAS score and sun index was analyzed with Pearson correlation test. Results A total of 100 subjects were included in this study. The median DPAS of the subjects was 9 (1–21). Right cheek had the highest median DPAS of 3 (0–6), followed by the left cheek with median DPAS of 3 (0–7). Men had a higher median DPAS score than women (9 vs 8). There was a significant difference between DPAS score and age (p<0.001). There was no significant correlation between DPAS score and sun index (r = −0.005; p = 0.957). Conclusion Factors associated with high DPAS score were cheek predilection, male, actively smoking, Fitzpatrick skin type IV, and increasing age. DPAS score has no correlation with sun index.
