[ skin For care Effectiveness test of composition]

Sodium dodecyl sulfate, an anionic surfactant, is applied daily to the skin to induce skin irritation, which causes the skin to dry out, to cause erythema on the skin, and to lose moisture due to the skin barrier function deterioration. For each skin care composition The skin moisture increase rate, erythema and transdermal water loss were tested to confirm that the skin function was restored and maintained.

For the test method, 5% aqueous solution of sodium dodecyl sulfate was applied to the inside of the subject's skin for 5 minutes and dried at room temperature. After 1 hour, skin moisture, erythema and transdermal water loss were measured for initial measurement.

Each of the skin care compositions prepared after 2 hours and 6 hours after application of a 5% aqueous solution of sodium dodecyl sulfate (hereinafter referred to as SDS aqueous solution) to the inside of the subject's skin was applied twice. After repeated daily for 2 weeks, measure the skin moisture, erythema and transdermal water loss in each test site as the final measurement. The skin improvement effect is evaluated by comparing the initial measurement value with the final measurement value for each test site. The skin measurements for each were repeated 5 times, and the subjects were subjected to 10 persons of 20-40 years of age to obtain an average value.

Mexameter MX18, Corneometer CM825, and Tewameter TM300 from CK Electronic GmbH of Germany were used as the test apparatus, and the results are shown in Tables 7 to 9 below.
