BACKGROUND Sunscreen use and dietary antioxidants are advocated as preventives of skin aging, but supporting evidence is lacking. OBJECTIVE To determine whether regular use of sunscreen compared with discretionary use or β-carotene supplements compared with placebo retard skin aging, measured by degree of photoaging. DESIGN Randomized, controlled, community-based intervention. (Australian New Zealand Clinical Trials Registry: ACTRN12610000086066). SETTING Nambour, Australia (latitude 26… 
Prevalence of Sun Protection Use and Sunburn and Association of Demographic and Behaviorial Characteristics With Sunburn Among US Adults
Sun sensitivity was significantly associated with a higher sunburn prevalence, independent of race/ethnicity, suggesting a need to consider sun sensitivity when identifying target demographic groups for sun safety interventions.

The effects of continuous application of sunscreen on photoaged skin in Japanese elderly people – the relationship with the usage
An inhibitory effect on photoaging symptoms such as spots and skin color tone non-uniformity is suggested by application of the appropriate amount of sunscreen over a long period of time in Japanese people, similar to Caucasians.
Sunscreens and Photoaging: A Review of Current Literature
Evidence suggests that visible light and infrared light may play a role in photoaging and should be considered when choosing a sunscreen, and further explores the requirements for an ideal sunscreen.
Relationship between SPF and UV Protection
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
Association of Sun-Protective Behaviors With Bone Mineral Density and Osteoporotic Bone Fractures in US Adults.
Routine use of sun-protective behaviors among the US adult population was not associated with decreased BMD or increased risk of osteoporotic fracture, and these reassuring findings add to the growing body of evidence on the safety of sun protection, with no considerable negative association with bone health.


A randomized controlled trial to assess sunscreen application and beta carotene supplementation in the prevention of solar keratoses.
Daily application of sunscreen retarded the rate of SK acquisition among adults in a subtropical environment, while a beta carotene supplementation of 30 mg/d had no influence on the occurrence of SKs.
Reduced melanoma after regular sunscreen use: randomized trial follow-up.
Melanoma may be preventable by regular sunscreen use in adults, and 10 years after trial cessation, 11 new primary melanomas had been identified in the daily sunscreen group, and 22 in the discretionary group, which represented a reduction of the observed rate.

The Pinnell paper in this issue of the Journal of Investigative Dermatology that examines ferulic acid combined with vitamins C and E shows that this formulation seems to provide two of the above defenses: a sunscreen effect, and an antioxidant effect.

Photoaging: prevention and topical treatments.
Enzymes that repair DNA damage or oligonucleotides that enhance the endogenous capacity for DNA damage repair may prove to be future preventive/therapeutic interventions for aging skin.
Differential Effects of Low-Dose and High-Dose Beta-Carotene Supplementation on the Signs of Photoaging and Type I Procollagen Gene Expression in Human Skin in vivo
30 mg/day of β-carotene supplementation is demonstrated to prevent and repair photoaging and improve facial wrinkles and elasticity significantly only in the low-dose group.
Can skin wrinkling in a site that has received limited sun exposure be used as a marker of health status and biological age?
Skin wrinkling in a site with limited sun exposure might be used as a marker of health status and, to some extent, biological age--particularly for women.
