Sunscreen

In order to achieve complete protection against the cumulative detrimental effects from sun exposure, topical strategies must shield against the range of solar wavelengths that can damage the skin. Existing examples of infrared-protective active agents include mitochondrially targeted antioxidants.

Sunscreens have been around for more than 70 years. This article will review some of the recent advances in photoprotection, including the development of sunscreen formulations offering higher and broader protection against solar radiation.

Ultraviolet (UV) radiation is a carcinogen that also compromises skin appearance and function. Since the UV action spectra for DNA damage, skin cancer, and vitamin D photosynthesis are identical, and vitamin D is readily available from oral supplements, why has sun protection become controversial?

The new generation of sunscreens serve an important role in overall skin protection from the sun. However, they should be used in conjunction with other sun protection measures such as sun protective clothing, hats, and sunglasses.

The skin has evolved to protect us from the harmful effects of ultraviolet light. Sunscreens were first developed to prevent sunburns by blocking UVB; they allowed us to prolong our time in the sun, but that resulted in increased exposure to UVA.

ROSASOL Cream is a novel topical formulation of 1% metronidazole in a vehicle containing sunscreens (SPF 15). This product has demonstrated efficacy in the treatment of inflammatory lesions, erythema, and telangiectasiae associated with rosacea.

This article will focus on cosmetic products that are designed to simulate tanning of the skin by coloring or staining the skin without sun exposure. The cosmetics may or may not contain a sunscreening agent, but the color produced is not protective. Certainly, a cosmetic tan is safe alternative for patients who use a tanning booth or worship the sun.

We review the various controversies surrounding sunscreen use.

Sunscreens have been in use for nearly 70 years. Originally designed to protect against sunburn, enable longer sun exposure and promote tanning, sunscreens are now often promoted as a method for preventing skin cancer and skin aging.
