  • Publication number: 20090298783
    Abstract: Disclosed is a method for preventing and/or soothing dry or sensitive skin against external stresses, comprising contacting the skin with a composition including an agent that decreases the release of granulocyte-macrophage colony-stimulating factor (GMCSF) from keratinocytes in the skin, wherein under conditions of external stress, dry or sensitive skin is soothed and/or prevented. Agents that decrease the release of GMCSF include silybin, piperine, tetrahydropiperine, nortrachelogenine, rhapontin, arctiin, artigenin and mixtures thereof. Also disclosed is a method of identifying an agent that decreases the level of GMCSF released from keratinocytes.
