Abstract:
PROBLEM TO BE SOLVED: To provide a ceramide production promoter and humectant for promoting the production of ceramide which is included in trace amounts in the whole organism but occupies the half or more of lipid components in the horny layer, the outermost layer of the skin, and plays an important role in moisture retention and barrier mechanisms of the skin, in which the ceramide is thought to be useful for prevention and improvement of dry skin, rough skin, atopic dermatitis, senile xerosis, psoriasis or the like.SOLUTION: The ceramide production promoter and humectant include an extract of Picea obovata as an active ingredient.
Abstract:

Abstract:
PROBLEM TO BE SOLVED: To provide a ceramide production enhancer which has a high ceramide production enhancement effect.SOLUTION: The ceramide production enhancer contains a compound expressed by general formula (1) as an active ingredient (in the formula, Rand Rrespectively independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon numbers; and Rand Rrepresent respectively independently a hydrogen atom, a hydroxy group or a methoxy group, or Rand Rform a six-membered ring including -CH=CHC(CH)O- together with carbon atoms to which they are bonded).
Abstract:
PROBLEM TO BE SOLVED: To provide a evaluating and determining method or the like of skin functions such as moisturizing function and barrier function of skin quickly and simply. SOLUTION: The method is provided for determining the skin function which includes measurement of an amount of ceramides in blood collected from trialist and determining skin barrier function based on the measured value concerned. Also, the evaluation or selection method of a skin functional improvement agent is provided which includes (A) the process where test articles are administrated to trialist or animal examinee, and (B) the process where amount of ceramides in blood is measured toevaluate the variation thereof.

Abstract:
PROBLEM TO BE SOLVED: To accurately determine the skin quality of a specimen by clarifying the relation between various skin quality and variation of a lipid component. SOLUTION: The skin quality of the specimen is determined by comparing the information about the lipid component whose composition ratio varies in relation to the skin quality obtained from the lipid composition information acquired from the specimen with a reference value calculated based on the lipid composition information acquired from an able-bodied person. Here, as a lipid component of the comparing object, for example sphingolipid, especially ceramide can be used. COPYRIGHT: (C)2009,JPO&INPIT
