Melasma is a multifactorial dyschromia that results from exposure to external factors (such as solar radiation) and hormonal factors (such as sex hormones and pregnancy), as well as skin inflammation (such as contact dermatitis and esthetic procedures), in genetically predisposed individuals. Beyond hyperfunctional melanocytes, skin with melasma exhibits a series of structural and functional alterations in the epidermis, basement membrane, and upper dermis that interact to elicit and sustain a focal hypermelanogenic phenotype. Evolution in the knowledge of the genetic basis of melasma and the cutaneous response to solar radiation, as well as the roles of endocrine factors, antioxidant system, endothelium proliferation, fibroblast senescence, mast cell degranulation, autophagy deficits of the melanocyte, and the paracrine regulation of melanogenesis, will lead to the development of new treatments and preventive strategies. This review presents current knowledge on these aspects of the pathogenesis of melasma and discusses the effects of specific treatments and future research on these issues.

“…Similarly, radiation exposure to the eye may be caused by anything as simple as reflecting sunlight off water or even the flash from a camera. Overexposure to UV light may lead to serious risks including cataracts and macular degeneration ( Duarte et al, 2015 ), ( D'Orazio et al, 2013 ).…”

Radiation is used in medicine to diagnose and treat diseases but it can also cause harm to the body by burning or mutation. This depends on whether the radiation is ionizing or nonionizing. Despite its vast applications in surgery, dermatology and cosmetics, little is taught and thus known about non-ionizing radiation. This review article discusses the fundamentals of non-ionizing electromagnetic radiations. The main aim is to extensively explain the different types of non-ionizing radiation. This will equip students and medical personnel with knowledge on different medical applications and expose them to a variety of specializations in medicine that utilize non-ionizing radiation. The article discusses the physics, hazard, means of protection and medical application of each type of radiation: ultraviolet radiation, light (both visible light and LASER), infrared radiation, microwaves and extremely low frequency radiation separately. It presents these terms in a simple manner that avoids rigors mathematics and physics, which makes them comprehensible for medical students. The development of new diagnostic and therapeutic approaches could also lead to increased hazards to the body unless they are treated with precaution. If not adequately monitored, a significant health risk may be posed to potentially exposed employees. Hence proper dosage should be used for non-ionizing radiation. This is only possible through understanding of the risks/benefits of these radiations by studying the physics and radiobiological effects of each individual radiation.

“…Nevertheless, individuals with high sensitivity to sun exposure (e.g., patients with melasma, rosacea, lupus erythematosus, or polymorphic light eruption) should be aware of sun radiation in shaded environments, especially in summer and in lower‐latitude zones. These individuals must be informed about the sun exposure related to household tasks performed in the shade and near windows and advised on the optimal positioning of their workstations (far from the windows), since the UVB, UVA, and BV irradiance from artificial lights and from electronic devices are also irrelevant 9,10 …”

“…These individuals must be informed about the sun exposure related to household tasks performed in the shade and near windows and advised on the optimal positioning of their workstations (far from the windows), since the UVB, UVA, and BV irradiance from artificial lights and from electronic devices are also irrelevant. 9,10 This study has limitations regarding the measurements, which were taken in a single day; moreover, infrared radiation was not assessed. Conversely, the results demonstrate the profile of solar radiation to which people can be exposed in their ordinary daily activities.…”

Sun exposure (UVB, UVA, and blue‐violet visible light) in ordinary daily situations

Sun exposure (UVB, UVA, and blue-violet visible light) in ordinary daily situations Dear Editor, Solar radiation is essential to human life; in addition to promoting warmth and well-being, it interacts with biological tissues causing metabolic changes, oxidative stress, and deoxyribonucleic acid (DNA) mutation. Different wavelengths elicit specific effects in the skin, such as sunburn, erythema, vitamin D synthesis, carcinogenesis, immunosuppression, photoaging, modulation of skin microbioma, and melanogenesis. 1,2The intensity of solar radiation that reaches the skin varies with altitude, latitude, the season of the year, reflective surfaces (e.g., water, grass, or snow), shadow, clothing, sunscreen use, length of exposure, and the time of day. Furthermore, the biological effect of sun exposure in the skin differs individually according to melanin pigmentation, genetic predisposition (e.g., the ability to repair DNA), photosensitizing drugs, antioxidant capacity, and skin disorders that are influenced by solar radiation.
