Sunscreens

Photoprotection is an essential component of many dermatologic therapeutic programs, which includes effective sunscreens. An ideal effective sunscreen should provide broad spectrum photoprotection (290-760), photostable, non-toxic, aesthetically acceptable and affordable. Sunscreens are broadly grouped as organic and inorganic. They protect against UV-A and UV-B rays preventing photodamage. The efficacy against UV-B rays is measured by sun protection factor and there is no universal consensus against UV-A protection. Various formulations are available improving the efficacy and aesthetics. Adverse effects are noted in 15-19% of the users. Desired protection is achieved with proper selection, application and compliance to the sunscreens. In addition to effective sunscreens, alternative protection measures like protective clothing and shade are necessary to obtain the maximum benefit.
