Current sunscreen controversies: a critical review

  title={Current sunscreen controversies: a critical review},
  author={Mark E. Burnett and Steven Q. Wang},
Background/purpose: Sunscreens are believed to be a valuable tool in providing photoprotection against the detrimental effects of UV radiation, a known carcinogen. However, a number of controversies have developed regarding their safety and efficacy. This review summarizes the relevant studies surrounding these controversies. 

Sunscreens: a review of health benefits, regulations, and controversies.

The role of ultraviolet radiation in causing skin cancer is looked at; the available evidence on both the beneficial and harmful effects of sunscreen use is summarized; and practical advice on how to advise patients to best protect themselves from photocarcinogenesis is concluded.

UV‐blocking potential of oils and juices

The potential for oils and fruit and vegetable juices to be substitutes for organic sunscreens shown to pass through the skin during wear is explored.

Photoprotection With Mineral-Based Sunscreens.

Mineral sunscreens are an attractive, efficacious option for consumers who prefer alternative choices in sun protection and safety concerns, including the controversy surrounding the use of nanoparticles are reviewed.

Does sunscreen use comply with official recommendations? Results of a nationwide survey in Germany

Recommendations for the correct use of sunscreen use: Sufficient amount of sunscreen should be applied at least 30 min before the sun exposure and should be reapplied every 2 h.

Sunscreens and Ultraviolet Light: What You Need to Know

It is important to understand how UV radiation affects the skin and how sunscreens work and current guidelines on sunscreen use and labeling.



The relation between sun protection factor and amount of suncreen applied in vivo

Theoretical calculations have suggested that the effective SPF is related to sunscreen quantity in an exponential way but this was not confirmed in vitro and has not been studied in vivo.

Quantity of sunscreen used by European students

Background The ability of sunscreen products to delay sun‐induced skin erythema is indicated by the sun protection factor (SPF), which is measured using an internationally agreed sunscreen thickness

Photoallergy to benzophenone.

The cases of four individuals with photoallergy to oxybenzone in sunscreens are reported, likely that such reactions will become more commonplace since oxyben Zone is by far the most frequently used agent in modern, high sun protection factor sun screens being marketed today.

Photocontact allergy to oxybenzone: ten years of experience.

The aims of this study were to establish the incidence of photocontact allergy to oxybenzone and its relationship with the use of other cosmetics, and to investigate the relationship between sunscreen agents and photoallergy.

The role of sunlight exposure in determining the vitamin D status of the U.K. white adult population

This data indicates that the current circulating 25‐hydroxyvitamin D level is low enough to be protective against a range of malignancies, but not high enough to cause disease.

Distribution of sunscreens on skin.

Sunbathers' application of sunscreen is probably inadequate to obtain the sun protection factor assigned to the preparation.

A large number of volunteers on a beach applied their own sunscreen all over the body and the amount of the applied sunscreen was on average 0.5 mg/cm2, indicating that the labelled SPF is probably considerably higher than the obtained degree of protection against sunburn.

High sun protection factor sunscreens in the suppression of actinic neoplasia.

The regular use of sunscreens can significantly reduce cutaneous neoplasia, as indicated by its suppression of precancerous lesions.

Photocontact dermatitis

ABSTRACT:  Photocontact dermatitis is not a common condition, but neither is it rare. Both photo‐irritant contact dermatitis (PICD) and photoallergic contact dermatitis (PACD) are seen by most

Contact and photocontact sensitivity to sunscreens

Clinicians should consider contact and photocontact allergy, especially in patients with photodermatoses and photo‐aggravated dermatoses and they should perform photopatch testing, and patients must be warned to avoid products containing the (photo)allergen.
