title: [Protective effect of tea pigments on mice skin photoaging induced by UV irradiation].
abstract: OBJECTIVE
  To study the protective effect of tea pigments on mice skin photoaging induced by UV irradiation.
  
  
  METHODS
  Total antioxidative ability and content of lipid peroxidation products malondialdehyde in the skin of mice were examined with colorimetry.
  
  
  RESULTS
  By ig or smearing, tea pigments could significantly improve total antioxidative ability and decline content of malondialdehyde in UV-irradiation-induced skin photoaging mice.
  
  
  CONCLUSIONS
  The results suggested that tea pigments could prevent mice skin from free radicals injury resulting from UV irradiation and moderate skin photoaging.
