From these plant extracts, it is possible to select only one kind and mix it in the external preparation for skin of the present invention, or to mix two or more kinds.

The amount of these plant extracts in the external preparation for skin of the present invention (hereinafter, the amount of the plant extract based on the dry weight) is 0.001 to 1% of the total amount of the external preparation for skin.
0.0% by weight is preferable, and 0.01 to 1.0% by weight is particularly preferable. This amount is 0.0% of the total amount of the external preparation for skin.
If the amount is less than 01% by weight, it is difficult to sufficiently exhibit the desired effect of reducing the stickiness of the desired saccharides, and it is not preferable. If the amount exceeds 10.0% by weight, the effect is increased in proportion to the increase in the blending amount. Not only is not expected, but also tends to be colored by the plant extract, which undesirably lowers the commercial value.

The saccharide incorporated in the external preparation for skin of the present invention is not particularly limited as long as it can be incorporated in cosmetics and the like as a humectant. For example, as monosaccharides, D-glyceraldehyde, dihydroxyacetone and the like can be used.
