PROBLEM TO BE SOLVED: To obtain a preparation for external use for skin capable of arresting collagen crosslinking in the epidermis, thus preventing skin aging, by formulating specific aminoethyl compound(s) and a tea extract. SOLUTION: This preparation contains pref. 0.001-1.0 (esp. 0.01-0.5)wt.% of one or two kinds of aminoethyl compounds of the formula (X is SO2 H or SO2 SH) and pref. 0.001-20 (esp. 0.01-10)wt.% of a tea extract. The preparation is capable of preventing skin from lowering in elasticity and from developing wrinkles/pouches due to skin aging by suppressing skin aging caused by sensility as well as ultraviolet light exposure from the sun.
