Ultraviolet (UV) radiation is the major environmental risk factor for nonmelanoma skin cancer and is a suspected risk factor for melanoma. Avoiding overexposure to direct sunlight during the peak daylight hours, wearing protective clothing, and applying sunscreen are ways to protect the skin. To provide clinicians with the tools to advise patients and to answer their inquiries, including which sunscreen to use, we review UV radiation’s effect on the skin, how sunscreens block UV light, current… 
Sunscreens and Ultraviolet Light: What You Need to Know
TLDR
It is important to understand how UV radiation affects the skin and how sunscreens work and current guidelines on sunscreen use and labeling.
Current principles of sunscreen use in children
TLDR
The interplay between UV radiation, sunscreens and the skin is reviewed, highlighting current controversies and recommendations surrounding sunscreen use, and evidence does not support an association between sunscreen use and melanoma, systemic toxicity or vitamin D deficiency.
Sunscreens in the United States: Current Status and Future Outlook.
TLDR
Although UVR induces endogenous cutaneous production of vitamin D, its damaging effects overshadow this positive benefit, especially in light of the ease of achieving recommended amounts of vitaminD through diet and supplementation.
Sunscreens: A review
Sunlight despite of source of life and energy creating major health challenges like sunburn, pigmentation, wrinkles, dermatitis, urticaria, ageing, immune-suppression and number of skin cancers too.
The sun--our friend or foe?
TLDR
UVR radiation is regarded as representing one of the most important environmental hazards for human skin, and the most dangerous chronic effects of carcinogenesis, and UVR may become the authors' ally in the treatment of selected skin disorders.
Sunce i koža – što moramo znati za pravilnu zaštitu?
Although the sun is the source of life, today it is generally known that exaggerated exposure leads to immunosuppression, rapid aging and skin cancer. However, the undesired effects of sunlight to
Comparison of the Photoprotective Effects of Sunscreens Using Spectrophotometric Measurements or the Survivability of Yeast Cells Exposed to UV Radiation
This work focuses on simple methods that allow comparison of the photoprotective effects of sunscreens. One such method described by Mansur and colleagues relies on the spectrophotometric
FORMULATION AND IN-VITRO EVALUATION OF SUN PROTECTION FACTOR IN A POLYHERBAL CREAM
Sunscreens aid the body's natural defense mechanisms to protect against harmful UV radiation from the sun. The present study involves the formulation of sunscreen cream with herbal active ingredients

Photoprotection by Sunscreens
TLDR
An ideal sunscreen assessment system would address both UVB and UVA protection, but the SPF rating should continue to serve as the major determinant of sunscreen efficacy.
Sunscreen abuse for intentional sun exposure
  • P. Autier
  • Medicine
    The British journal of dermatology
  • 2009
TLDR
Three randomized trials showed that sunscreen use by sun sensitive subjects engaging in intentional sun exposure could increase the duration of exposure without decreasing sunburn occurrence, which could be the reason why melanoma risk is increased when sunscreen is used.
The deceptive nature of UVA tanning versus the modest protective effects of UVB tanning on human skin
TLDR
Although visual skin pigmentation (tanning) elicited by different UV exposure protocols was similar, the melanin content and UV‐protective effects against DNA damage in UVB‐tanned skin (but not in UVA‐ tanned skin) were significantly higher.
An Analysis of UVA Emissions from Sunlamps and the Potential Importance for Melanoma
TLDR
Typical sunlamp use results in an approximate doubling of annual effective dose, if the XFM action spectrum is applied, but frequent use can increase the annual effective XFM dose by as much as 6 times what would be received from the sun alone for fluorescent sunlamps and asMuch as 12 times for newer, high‐pressure sunlamping.
Sunscreen Use and the Risk for Melanoma: A Quantitative Review
TLDR
This meta-analysis of 18 casecontrol studies found no good evidence for an increased risk for melanoma with sunscreen use, and the strength and the consistency of the observed associations between melanoma and sunscreen use were examined.
Reduction of solar keratoses by regular sunscreen use.
TLDR
Regular use of sunscreens prevents the development of solar keratoses and, by implication, possibly reduces the risk of skin cancer in the long-term.
Regulation of human skin pigmentation and responses to ultraviolet radiation.
TLDR
This review summarizes current understanding of the regulation of constitutive human skin pigmentation and responses to UV radiation, with emphasis on physiological factors that influence those processes.
High ultraviolet A protection affords greater immune protection confirming that ultraviolet A contributes to photoimmunosuppression in humans.
TLDR
It is demonstrated that ultraviolet A contributes greatly to human immune suppression and that a broad-spectrum sunscreen with high ultraviolet A filtering capacity results in immune protection that exceeds erythema protection and that highraviolet A protection is required to protect against ultraviolet-induced damage to cutaneous immunity.
