VALLEJO, EO et al. Genetics perspective of UV rays and new alternatives for sun protection. Rev. argent. dermatol. [online]. 2013, vol.94, n.3. ISSN 1851-300X.

Ultraviolet (UV), has three different wavelengths: UVA (315-400 nm), UVB (280-315 nm) and UVC (100-280 nm), which impact in different ways on the skin of human beings, and may be responsible of skin aging, burns and cancers. Currently we have multiple sunscreen alternatives, ranging from conventional physical methods to complex molecular mechanisms and inducers of cell repair as Polypodium leucotomos. The purpose of this review is to show the implications of ultraviolet rays on human beings exposed to sunlight and the protection alternatives that are available and show what is to come in photo protection towards the future.
