“…However, there is still debate whether it provides adequate protection against MM and nevus induction. Inadequate sunscreen application has been found to be a common failing leading to deficient photoprotection 27,28 . There is increasing evidence that a number of substances when taken orally exert a preventive effect against UV‐induced skin damage without adverse effects.…”

Background UV radiation and the presence of melanocytic nevi are the main risk factors of sporadic melanoma (MM). Protection of skin by an oral photoprotective agent would have substantial benefits. Objective We investigated the possible role of an oral Polypodium leucotomos (PL) extract to improve systemic photoprotection in patients at risk of skin cancer analyzing the ability to decrease UV‐induced erythema. We also studied the interaction among MC1R polymorphisms and CDKN2A status with the minimal erythematous dose (MED) and their influence in the response after oral PL. Methods A total of 61 patients (25 with familial and/or multiple MM, 20 with sporadic MM and 16 with atypical mole syndrome without history of MM) were exposed to varying doses of artificial UVB radiation without and after oral administration of a total dose of 1080mg of PL. Results Oral PL treatment significantly increased the MED mean in all group patients (0.123 to 0.161 J/cm2, p<0.05). Although not significant, we noticed a stronger effect of PL on the MED of patients with familial MM compared to those with MM (U=273, p=0.06). Among the patients with familial MM, those exhibiting a mutated CDKN2A and/or polymorphisms in MC1R had the bigger differences in response to treatment with PL. Limitations Reduced number of patients. No control population. Conclusions Administration of PL leads to a significant reduction of sensitivity to UVR (p<0.05) in all patients. Dark‐eye patients and patients with higher UVR sensibility (lower basal MED) would be the most benefited from oral PL treatment.

“…There were several behavioral studies on sunscreen use that aimed to identify the difference between theoretical UVPE (ie, labeled SPF) and actual UV protection and to find out ways to improve UV protection . Most of those studies showed that the amount of applied sunscreen in real‐life situations was significantly lower than the amount defined in the ISO24444.…”

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.

“…Under controlled conditions, appropriate application of sunscreens has been shown to prevent skin cancer [13,14]. However, in real lifedespite the improved galenic properties of sunscreensstill lower (1.0-1.5 mg/cm 2 ) than recommended (2.0 mg/cm 2 ) [16] amounts of sunscreen are used, leading to reduced UV protection and to sunburn [17,18]. In this study, not the amount used by volunteers but the sunscreen application habits and the relative total body coverage after applying the cream according to their typical application routine were the main objectives of evaluation.…”

OBJECTIVE: This study aimed to assess sunscreen application habits and relative body coverage after single whole body application. METHODS: Fifty-two healthy volunteers were asked to use the test product once, following their usual sunscreen application routine. Standardized UV photographs, which were evaluated by Image Analysis, were conducted before and immediately after product application to evaluate relative body coverage. In addition to these procedures, the volunteers completed an online self-assessment questionnaire to assess sunscreen usage habits. RESULTS: After product application, the front side showed significantly less non-covered skin (4.35%) than the backside (17.27%) (P = 0.0000). Females showed overall significantly less non-covered skin (8.98%) than males (13.16%) (P = 0.0381). On the backside, females showed significantly less non-covered skin (13.57%) (P = 0.0045) than males (21.94%), while on the front side, this difference between females (4.14%) and males (4.53%) was not significant. CONCLUSION: In most cases, the usual sunscreen application routine does not provide complete body coverage even though an extra light sunscreen with good absorption properties was used. On average, 11% of the body surface was not covered by sunscreen at all. Therefore, appropriate consumer education is required to improve sunscreen application and to warrant effective sun protection.R esum e OBJECTIF: Le but de l' etude pr esente etait d' evaluer les habitudes d'application de l' ecran solaire et la couverture relative du corps apr es une seule application sur le corps entier. M ETHODES: Cinquante-deux volontaires saints ont et e invit es a utiliser le produit d'essai une seule fois suivant leur routine d'application solaire habituelle. Pour evaluer la couverture relative du corps, des photographies UV normalis ees evalu ees par analyse d'image ont et e men ees avant et imm ediatement apr es l'application du produit. En plus, les volontaires ont compl et e un questionnaire d'auto-evaluation electronique pour evaluer les habitudes d'utilisation d' ecran solaire. R ESULTATS: Apr es l'application du produit, la face avant a montr e significativement moins de peau non couverte (4.35%) que l'arri ere (17.27%) (P = 0.0000). Globalement, les femmes ont laiss e moins de peau d ecouverte (8.98%) que les hommes (13.16%) (P = 0.0381). A l'arri ere, les femmes ont laiss e significativement moins de peau d ecouverte (13.57%) (P = 0.0045) que les hommes (21.94%) alors que devant la diff erence entre les femmes (4.14%) et les hommes (4.53%) n' etait pas significative. CONCLUSIONS: Dans la plupart des cas, la routine habituelle d'application d' ecran solaire, ne r esulte pas dans une couverture compl ete du corps, même si un produit ayant des bonnes propri et es cosm etiques est utilis e. En moyenne, 11% de la surface corporelle n' etait pas couverte par le produit. Par cons equence, il est n ecessaire de former le consommateur pour am eliorer l'application d' ecran solaire et pour garantir une protection solaire ef...
