Sunlight as a source of life for humans and the earth did not always give beneficial effects for humans because it can cause a variety of losses to human skin from ultraviolet rays contained in sunlight. Experts say one skin adverse impacts to human skin is the appearance of premature aging caused by ultraviolet light exposed to continuous.

But not all ultraviolet rays can damage human skin tissue hanging from long range and wave energy that is raised so that the damage occurred in several stages. For example, infra red produced from the sun has a wavelength range and an energy of 1760 nm and 3000 nm and visible wavelengths has only 400 nm to 760 nm. In this phase the low energy no effect in the skin.

Utraviolet C or UVC which has a wavelength less than 290 nm can still be filtered into the category of the ozone layer so no worry of skin damage. "The wavelength UVC, infrared and visible can not be measured directly by humans, so often the light that hits our skin can be ignored," he said. Inne reminded to be careful if ultraviolet B (UVB) and ultraviolet A (UVA) has been addressing the human skin with the power of the wavelength and energy of 290 nm and 320 nm and 320 nm and 400 nm.

He said the UVB and UVA occurs in tropical countries like Indonesia and the Indonesian women in particular are expected to be more careful and can maintain skin moisture.

He suggested compulsory body lotion applied to the skin after a bath and a few hours once if it has been long in air-conditioned room. In addition, maintaining sufficient water that enters the body can also be trusted as an effort to moisture. In addition to the ultraviolet, air pollution, cigarette smoke, pesticides, industrial smoke, alcohol consumption and poor nutrition may be one driver of premature aging.
