Sunscreens and Antioxidants as Photo- Protective Measures: an Update

There are many photo-protective measures adopted for protection from the solar radiation especially the UV radiation spectrum, sunscreens being the main agents. Besides the traditional approach of topical use of sunscreens, both chemical and physical, a new approach has emerged to use systemic agents in the form of vitamins and minerals. In this review, we are describing the major aspects relat...

An Update on Sunscreens II

1 This educational resource summarises recent developments in sunscreen research, knowledge, and use. It starts with a review of the Nambour Skin Cancer Prevention Trial, which contributes to the evidence for a protective effect of sunscreen against melanoma. This is followed by consideration of UVA protection, correct application of sunscreen, skin type in sun protection, and compliance with s...

In Vitro Evaluation of Sunscreens: An Update for the Clinicians

Topical sunscreens contain molecules or molecular complexes that can absorb, reflect, or scatter UV photons. Evaluation of the efficacy of sunscreen products has been made through the Sun Protection Factor (SPF), a mean of quantitatively assessing in vivo the degree of protection offered by sunscreen products against solar radiation. In vivo evaluation of SPF has several drawbacks. First of all...

A potential role for endogenous proteins as sacrificial sunscreens and antioxidants in human tissues

Excessive ultraviolet radiation (UVR) exposure of the skin is associated with adverse clinical outcomes. Although both exogenous sunscreens and endogenous tissue components (including melanins and tryptophan-derived compounds) reduce UVR penetration, the role of endogenous proteins in absorbing environmental UV wavelengths is poorly defined. Having previously demonstrated that proteins which ar...
