ABSTRACT
Sunlight includes infrared light photons, visible light
and ultraviolet light (UVL) photons. UVL is the main
cause of skin cancer and photo-aging. It is absorbed
by chromophores in the skin, such as melanin,
DNA, RNA, proteins, lipids and aromatic
aminoacids. The absorption of UVL results in photochemical
reactions involving reactive oxygen species
(ROS) with the consequent damages to the
skin. UVL, through different photochemical modifications
forming cyclobutane dimmers, produce
mutations to cells phenomenon called neoplasic
transformation. The protection of the skin against
sunlight is the main action to prevent skin cancer
and photo-aging. Photo-protection is an effective
method for preventing skin damage and its consequences.
The objective of this consensus was to
discuss and propose a Statement Position Paper
on photo-protection and useful measures for their
application by the dermatologist and general practitioner
in Mexican population.
