Moisturising composition comprises a Simarouba plant extract, amino acids and ceramides. The composition may also contain an unsaturated fatty acid or ester. The composition preferably contains (by weight) 5-20% Simarouba extract, 55-85% amino acids, 3-10% ceramides and 0-15% unsaturated fatty acid or ester. The amino acids are especially selected from L-lysine, L-citrulline, L-threonine and L-histidine. The ceramides are especially plant (e.g. wheat) glycoceramides. The unsaturated fatty acid or ester is especially selected from linoleic acid, oleic acid, tocopheryl linoleate or oleate, and 1-12C alkyl esters, e.g. decyl oleate or ethyl linoleate (vitamin F). |
