“…This leads to an impaired immune surveillance, which, in turn, can favor cancer development [57]. In addition, there is clinical evidence that shows that UVr is strongly related to photoaging [58,59,60]. In the last few years, oral probiotic treatment has been proposed as an interesting alternative approach for photoprotection, which may be useful in reducing photoaging, UV-induced immunosuppression and cancer development.…”

At the beginning, probiotics were used exclusively for gastrointestinal conditions. However, over the years, evidence has shown that probiotics exert systemic effects. In this review article, we will summarize recent reports that postulate probiotic treatment as an efficient one against skin pathologies, such as cancer, allergy, photoaging and skin infections. The focus will be restricted to oral probiotics that could potentially counteract the ultraviolet irradiation-induced skin alterations. Moreover, the possible underlying mechanisms by which probiotics can impact on the gut and exert their skin effects will be reviewed. Furthermore, how the local and systemic immune system is involved in the intestine-cutaneous crosstalk will be analyzed. In conclusion, this article will be divided into three core ideas: (a) probiotics regulate gut homeostasis; (b) gut and skin homeostasis are connected; (c) probiotics are a potentially effective treatment against skin conditions.

“…Living body tissues have high reactivity to ultraviolet (UV) radiation that is present in natural sunlight. Therefore, protecting the human skin from UV damage is one of the main issues in dermatology and cosmetology, particularly regarding the prevention of cancer, premature aging, and pigmentation changes . Sunscreen is often used to protect the human skin from UV damage, and the most popular index of UV protection efficacy (UVPE) for sunscreen products is the sun protection factor (SPF) value, which is prominently displayed on products offered for sale.…”

[2][3][4] Sunscreen is often used to protect the human skin from UV damage, and the most popular index of UV protection efficacy (UVPE) for sunscreen products is the sun protection factor (SPF) value, which is prominently displayed on products offered for sale. Because SPF is a ratio calculated from the energies required to induce a minimum erythema response with and without in vivo sunscreen, it certainly shows the protection efficacy for sunburn.…”

BackgroundProtection of the human skin from ultraviolet (UV) damage is one of the main issues in dermatology and cosmetology. The UV protection efficacy (UVPE) of the sunscreen film is decreased by sweat, sebum, and friction during the day. However, the technical relationship between the UVPE evaluated in a laboratory and the actual protection in daily use has not been clarified, because the UVPE measurement method in real‐life setting has not been established. This study aimed to develop a novel UVPE evaluation system that allows in situ monitoring of the UVPE in real‐life activities.MethodsThe multispectral UV polarization reflectance imaging system (MUPRIS) and a UVPE estimation algorithm were developed. The diffuse reflectance spectra were measured for a total of 48 sunscreen materials that were applied on 59 subjects. The UVPEs estimated from the diffuse reflectance spectra were compared with the in vivo SPFs. Finally, the UVPE before and after a marine leisure activity was evaluated using the MUPRIS as the practical use test.ResultsCompared with the conventional UV camera, the MUPRIS could visualize the applied sunscreen more clearly and showed good UVPE estimation accuracy (correlation coefficient for in vivo SPF, 0.82). In the practical use test, the degradation of the UVPE during a marine leisure activity was quantitatively monitored and was validated by the actual occurrence of sunburn.ConclusionsA novel in situ UVPE monitoring tool had been successfully developed. It can strongly support the development of innovative sunscreen products that can perfectly protect customers against UV irradiation in real‐life situation.

Introduction:The term photoaging describes the sun damaging effects on skin mainly due to chronic ultraviolet (UV) light exposure. The unsatisfactory results of the available anti-aging strategies raise the demand for alternative forms of treatments. Adipose-derived stem cells (ASCs) are available in abundant quantities, harvested by a minimally invasive procedure, safely transplanted and differentiated along multiple cell lineages. Subsequently, used in treatment of many diseases. Aim: To assess the potential ability of ASCs to ameliorate skin changes induced by chronic exposure to artificial light source similar to the sun rays in its UVA and UVB spectrum in adult female guinea pigs. Material and Methods: Adipose-derived stem cells were isolated from subcutaneous white adipose tissue of five adult human donors undergoing elective liposuction surgery. Twenty adult female guinea pigs were used and were randomly divided into two groups each was subdivided into two subgroups "five animals, each". Subgroup IA served as the control group. Subgroup IB was intradermally injected with phosphate buffered saline solution. Subgroup IIA served as the photoaging model. Subgroup IIB served as the photoaging model intradermaly injected with ASCs. Isolated stem cells were cultured and characterized. Skin specimens were prepared and examined using different histological and immunohistochemical techniques. Morphometric and statistical studies were also performed. Results: Subgroup IIA showed various UV damaging effects in the skin epidermis and dermis, while ASCs injection in subgroup IIB resulted in partial restoration of the skin structure. Conclusion: Intradermal injection of ASCs partially ameliorated the photo-damaging effects. Further studies are needed before ASCs clinical application.
