It is a fact that skin changes when growing older, as a result of a lifetime of exposure to environmental agents, personal habits such as smoking and diet, and modifications that happen in the normal process of cellular aging. The skin starts appearing less smooth and tight than before, which can lead to visible sagginess, lines, and wrinkles, among other evidence.
In the past several years, there has been much public debate about the importance of sunlight exposure for maintaining adequate levels of vitamin D, versus the importance of daily protection against solar ultraviolet (UV) radiation. Vitamin D is known to play an important role in bone health and maintaining muscle control.
UV absorbers are substances with the capacity to absorb UV light in the range between 100 and 400 nm and to convert it to a lower level of radiated energy, e.g. radiation in the form of fluorescence or heat. This radiation is not usually capable of causing damage to the product or to the skin.
