To obtain a sebum secretion-inhibiting cosmetic which is useful in inhibition of sebum secretion on the skin and scalp by using a lipid higher in the polarity than cholesterol.
Skin surface lipid of mammalian animals is extracted with an organic solvent, for example, chloroform, preferably at 5-40°C for 1-3 minutes, subjected to chromatography and eluted sequentially with a hexane/diethyl ether 1:1 volume ratio mixture, a hexane/diethyl ether 1:1 volume ratio mixture, and further with a higher polar solvent than the hexane/diethyl ether mixture (for example, an ether such as diethyl ether) to collect the fraction containing a lipid component higher than cholesterol in polarity (sebum lipid synthesis inhibitor). This inhibitor is formulated to a cosmetic in an amount of 0.01-50wt.% and is used as a sebum secretion-inhibiting cosmetic (cosmetic of external use for skin or for hair growth and restoration).
