The influence of stress factors on human skin induces the production of free radicals. Free
radicals react immediately with antioxidants contained in the skin, giving rise to their …

Production of free radicals in the human skin subsequent to IR irradiation has been
demonstrated by means of two different methods. The first technique, based on resonance …

The influence of the ultraviolet (UV) irradiation of the sun on the formation of free radicals in
human skin is well investigated. Up to now, only small amounts of data are available stating …

Resonance Raman spectroscopy was used as a fast and non-invasive optical method for
the determination of the influence of IR radiation on the degradation of carotenoid …

UV irradiation is one of the most harmful exogenous factors for the human skin. In addition to
the development of erythema, free radicals, that is reactive oxygen species (ROS), are …

In contrast to ultraviolet and infrared irradiation, which are known to facilitate cutaneous
photoaging, immunosuppression, or tumour emergence due to formation of free radicals and …

It is well known from the literature that carotenoid antioxidant substances decrease after the
irradiation of the skin with UV light. Available literature has shown no information about the …

Resonance Raman spectroscopy was used for the fast in vivo detection of the concentration
of carotenoid antioxidant substances such as beta‐carotene and lycopene in human skin …

Environmental factors like air pollutants, radiation of the sun and stress factors such as
illness, smoking, or alcohol abuse produce free radicals in the human tissue as well as in …

The predominant long-chain carotenoids found in human skin are lycopene and β-carotene.
They are powerful antioxidants and thought to act as scavengers for free radicals and singlet …
