SOLUTION: This skin preparation for external use contains a compound of formula I [R1 is H, a 1-12C alkyl; R2, R4 are each H or a lower alkyl; R3 is H, a (substituted) alkyl or aralkyl; R5 is H, or is combined with R3 and the adjacent nitrogen atom to form a heterocyclic ring] (for example, a compound of formula II) preferably in an amount of 0.0001-40 wt.%, especially preferably 0.01-20 wt.%. The compound of formula I is obtained, for example, by reacting a glycinamide derivative of formula III with a halocarboxylic acid derivative of formula IV in the presence of a base such as sodium hydroxide at 20-200 deg.C for 10 min to 24 hr, neutralizing the reaction product with an acid such as hydrochloric acid, properly drying the product, and then isolating the product.

Test Example 2 Wrinkle Inhibition Test Using Hairless Mice A hairline mouse (HR / ICR, 6 weeks old at the start of the experiment) was irradiated on the back with a health line lamp (manufactured by Toshiba, SE20) at a dose of 1 MED. Adjust UV-B as follows
Light irradiation was performed. Immediately thereafter, 100 μl of an 80% ethanol solution containing Compounds 1 to 9 in the amounts shown in Table 4 was applied (Test Nos. 11 to 19). This work was performed for 20 weeks. As a control, an 80% ethanol solution containing no carboxyalkylamine derivative (1) or a salt thereof was similarly applied (Test No. 10). The irradiation energy amount is UV-Radiometer (TOKYOOPT)
It was measured using ICAL Co., Ltd., UVR-305 / 365D). After completion of the test, the frequency of the formed wrinkles was visually evaluated according to the following criteria (wrinkle index). Table 4 shows the results. ◎ Wrinkle index 0: No wrinkle formed 1: Wrinkle slightly formed 2: Wrinkle trace formed 3: Slight wrinkle formed 4: Wrinkle formed firmly

Test Example 3 Test for Maintaining Skin Elasticity Using Rats Both soles of 3-week-old SD male rats were divided into four groups. After UV-B light (1 MED or less) was irradiated to the third and fourth groups, 10 μl of an 80% ethanol solution containing the compound 1 or 3 in an amount shown in Table 5 was applied per foot. This work is 1
The test was performed three times a week every other day or every other day for 6 weeks (test numbers 22, 23). The second group includes 80% containing no carboxyalkylamine derivative (1) or a salt thereof.
An ethanol solution was similarly applied (Test No. 21). Nothing was applied to the first group (test number 20). The elasticity of the skin was measured by using a cute meter SES575 (manufactured by Courage Kazaka), suctioning it at 500 mb for 3 seconds, releasing it, and then measuring the displacement for 3 seconds for a total of 6 seconds. The measurement was performed five times per foot, and the Ue value and the Uf value were determined. Next, the sole of the rat was taken from Melcox (Dainippon Ink Co., Ltd.)
The solution was fixed by refluxing, digested with formic acid, and analyzed for linearity of the elastic fiber by a scanning electron microscope (SEM). Analysis was performed by the method of Imokawa et al. (J. Invest. Dermatol., 10
5, 254-258 (1995)). That is, for each sample, 10 representative SEM photographs were extracted from a 1000-fold SEM photograph, enlarged, copied, and then equally divided into 16 parts. An arbitrary elastic fiber was extracted from each region, and was traced on a transparent film with a line having a constant thickness (8 pixels width). The linearity of the elastic fiber is represented by A / (B ×
C). For example, if the torres of the elastic fibers are straight, the linearity is 1. Table 5 shows the results.

Test Example 4 Mouse Hair Growth Inhibition Test The back hairs of 10 6-week-old C3H mice were shaved using an electric clipper and an electric shaver over 2 × 4 cm 2 without damaging the skin. Compound 1 on shaving site
An 80% ethanol solution containing 9 in the amount shown in Table 6 was applied twice a day in 100 μl portions for 4 weeks (test numbers 24-32). As a control, an 80% ethanol solution containing no carboxyalkylamine derivative (1) or a salt thereof was similarly applied (control group). Three weeks later, the shaved portions of the test numbers 24-32 and the control group were photographed at a fixed magnification.
The regenerated hair was observed using an image analyzer, the regenerated hair area ratio (regenerated hair area / shaved area) was determined, and the hair growth inhibition rate (1-
