Given the popularity of a tan appearance, sunless tanning may play a role in skin cancer prevention as a substitute for ultraviolet (UV) tanning. Few studies have comprehensively assessed attitudes toward sunless tanning or predictors of use.Demographic, phenotypic, and lifestyle characteristics were ascertained during in-person interviews of 385 non-Hispanic whites (<age 40) who were controls in a case-control study of early-onset basal cell carcinoma. Attitudes toward sunless tanning were queried via self- administered questionnaire...

Cutaneous field cancerization (CFC) is associated witha high-risk of developing cutaneous squamous cellcarcinoma (cSCC). It manifests as actinic keratoses(AK) as one of the few macroscopic alterations in CFCpatients. A prospective, single-arm, case-series wasperformed to evaluate the utility of a novel sunscreencontaining DNA-photolyase for treatment of CFCin nine subjects (mean age 70.6 years, male: femaleratio 5:4). The cream was applied topically twicedaily on CFC/AK areas and patients were followedup for three months, with no other treatments...

The ability of metal oxide nanoparticles to penetrate the skin has aroused a great deal of interest during the past decade due to concerns over the safety of topically applied sunscreens that contain physical UV-resistant metal particles, such as nano-Zinc oxide (nZnO). Previous studies demonstrate that metal oxide nanoparticles accumulate in skin furrows and hair follicles following topical application while little is known about the consequence of these nanoparticles on skin homeostasis. The current investigation tested the effects of nZnO (0...

TiO2 nanoparticles (TiO2 NPs) are employed in many products (paints, personal care products, especially sunscreens, plastics, paper, water potabilization and food products) and are then released into the environment from these products. These nanoparticles present potential risk to freshwater and marine microalgae. The primary toxicity mechanism is adsorption between NPs and microalgae (heteroagglomeration); however, studies of interactions of this kind are scarce. We investigated the heteroagglomeration process that occurs between two forms of TiO2 material, nanoparticles and bulk, and three different microalgae species, and under different environmental conditions (freshwater and marine water), in order to assess the influence of pH and ionic strength (IS)...

BACKGROUND/AIM: The main reason for extrinsic skin aging is the negative action of free radicals. The formation of free radicals in the skin has been associated with ultraviolet (UV) exposure and also to visible (VIS) and near-infrared (NIR) irradiations. The aim of the present study was to evaluate the efficacy of a sunscreen in the whole solar range. METHODS: The radical-scavenging activity of a sunscreen in the UV, VIS, and NIR ranges was evaluated using electron paramagnetic resonance spectroscopy...

BACKGROUND: Organ transplant recipients (OTRs) are at an increased risk of developing a de novo malignant neoplasm compared to the general population. The primary contributor to skin cancer in all patients is sun exposure. OBJECTIVE: In this study, we aim to ascertain both OTR skin cancer awareness and photoprotection practices. METHODS: A questionnaire-based study of Saskatchewan transplant recipients. RESULTS: Nearly all respondents were aware that sun exposure is the best-known cause of skin cancer and that as an OTR, they are at increased risk of skin cancer (99...

Titanium dioxide nanoparticles (TiO2NPs) are used in sunscreen products to protect the skin from the sun's ultraviolet rays. However, following exposure to sunlight, the photocatalytic activity of TiO2NPs can produce an excess of reactive oxygen species (ROS), causing skin cell damage, triggering an inflammatory response. In zebrafish model, we evaluated how well Pro-NP™ (biodegradable NPs containing superoxide dismutase and catalase) could protect them from TiO2NP-induced photo-oxidative stress. We hypothesized that the antioxidant properties of Pro-NP™ would protect zebrafish embryos from the phototoxic effects of TiO2NPs, improving overall survival and growth...

Truth, like knowledge, is surprisingly difficult to define. Indeed, every definition of truth that philosophers have developed falls prey to the question, "Is it true?". In this essay we consider what is the true SPF of a sunscreen product and whether it can ever be realizable. This article is protected by copyright. All rights reserved.

UV radiation exposure is the major contributor to photocarcinogenesis and photoageing. Reducing UV radiation exposure can be achieved by using adequate sunscreen preparations. The use of sunscreen can significantly reduce the incidence of squamous cell carcinoma, actinic keratoses and invasive melanoma. In the Australian market over 900 sunscreen products are available, each with their own brand, formulation and ingredients. It can be difficult for dermatologists and consumers to determine which are the most effective and appropriate products to use...

Zinc oxide nanoparticles (ZnONPs) are widely used in our daily life, such as in sunscreens and electronic nanodevices. However, pulmonary exposure to ZnONPs causes acute pulmonary inflammation, which is considered as an initial event for various respiratory diseases. Thus, elucidation of the underlying cellular mechanisms of ZnONPs can help us in predicting their potential effects in respiratory diseases. In this study, we observed that ZnONPs increased proinflammatory cytokines, accompanied with an increased expression of aryl hydrocarbon receptor (AhR) and its downstream target cytochrome P450 1A1 (CYP1A1) in macrophages in vitro and in mouse lung epithelia in vivo...

Sunlight is indispensable for life. Skin aging is determined not only by genetic factors but also by the influence of solar radiation which in all its spectral regions induces free radicals in the human skin. Below a critical concentration, free radicals are important for signaling processes in the human body. Exceeding a critical threshold value (FRTV), however, free radicals lead to cellular damage which, in turn, can induce skin aging, immunosuppression and even skin cancer. Recently it could be shown that 50% of the free radicals induced in the human skin by solar radiation were caused by the visible and infrared spectral regions...

BACKGROUND: Information is lacking on the dermal penetration of topically applied formulations on in vitro skin models, under conditions where the stratum corneum (SC) is damaged. Therefore, we have developed a standardized in vitro barrier-disrupted skin model using tape stripping. METHODS: Different tape stripping conditions were evaluated using histology, transepidermal water loss, infrared densitometry, and caffeine absorption. RESULTS: The effects of tape stripping were comparable using pig and human skin...

Patients with rosacea present a challenge to the dermatologist, as they typically possess sensitive skin, need facial Demodex and bacterial colonization control, exhibit vasomotor instability, require camouflaging of telangiectatic mats, and desire prescription treatment. Currently available pharmaceuticals are aimed at inflammation reduction, primarily with the use of topical and oral antibiotics. Recently, vasoconstrictor formulations have emerged, but these drugs have only a temporary effect and improve appearance without addressing the underlying cause, which remains largely unknown...
