Relationship factors and couples’ engagement in sun protection [PDF]

open access: yesHealth Education Research, 2016
Individuals may be more motivated to adopt health practices if they consider the benefits of these behaviors for their close relationships. The goal of this study was to examine couple concordance with sun protection and use the interdependence and communal coping theory to evaluate the role of relationship factors in sun protection.

Investigation of Model Sunscreen Formulations Comparing the Sun Protection Factor, the Universal Sun Protection Factor and the Radical Formation Ratio [PDF]

open access: yesSkin Pharmacology and Physiology, 2015
In view of globally rising skin cancer rates and harmful effects exerted by sunlight throughout the ultraviolet, visible and infrared ranges, an objective, safe and comprehensive method for determining sunscreen efficacy is required in order to warrant safe sun exposure.

Revisiting the Role of Irradiance in the Determination of Sunscreens’ Sun Protection Factor [PDF]

open access: yesThe Journal of Physical Chemistry Letters, 2020
The efficacy of a sunscreen tends to be associated with its sun protection factor (SPF) value, a figure determined in a test that relies on the independence of the SPF value to both UV radiation dose and irradiance. We probe these assumptions when photoinduced product degradation is present, and we estimate that the theoretical limit for their validity

Evaluating the Sun Protection Factor of Cosmetic Formulations Containing Afzelin

open access: yesChemical and Pharmaceutical Bulletin, 2021
Exposure to UV radiation damages the skin and increases the risk of skin cancer. Sunscreen is used to protect the skin from the harmful effects of UV radiation. However, the chemical UV filters used in sunscreen can show toxicity and cause allergic reactions.

Machine learning for the prediction of sunscreen sun protection factor and protection grade of UVA [PDF]

open access: yesExperimental Dermatology, 2019
AbstractWe report a prediction model for sunscreen sun protection factor (SPF) and protection grade of ultraviolet (UV) A (PA) based on machine learning. We illustrate with real clinical test results of UV protection ability of sunscreen for SPF and PA.

Correlation of in vivo and in vitro measurements of sun protection factor

open access: yesJournal of Food and Drug Analysis, 2020
In this study, the correlation of measuring sun protection factor (SPF) values between in vivo and in vitro tests was investigated for the purpose of monitoring the in vivo efficacy of sunscreen products using in vitro tests instead of in vivo tests to lessen the labor burden. Eight products, including standard product of the US FDA (SPF 4) and COLIPA (

Effectiveness of sunscreens and factors influencing sun protection: a review

open access: yesBrazilian Journal of Pharmaceutical Sciences, 2022
The effectiveness of sun protection depends directly on the photo-protective product employed, the way it is used and the amount applied. Many studies report that sunscreens are often applied incorrectly, at amounts much lower than those recommended for the sun protection factor (SPF) specified on the label. When not used properly, the effectiveness of

Social Differentiation of Sun-Protection Behaviors

open access: yesAmerican Journal of Preventive Medicine, 2016
Adherence to sun-protection guidelines in developed countries is low, especially among people of low SES. Mechanisms underlying this social differentiation are poorly understood. This study aimed to examine the social differentiation of sun-protection behaviors and of two cognitive factors (knowledge about both sun health and behavioral risk factors ...

Determination Of Sun Protection Factor By Uv-Vis Spectrophotometry

open access: yesHealth Care : Current Reviews, 2016
Background: Sunscreen products contain active ingredients that can absorb, reflect or scatter the sunlight, depending on their nature. We can evaluate the effectiveness of a sunscreen by determining the sun protection factor (SPF). This SPF should be specific for each phototype, so as to the protection against the damaging effects of UV rays may be the
