ABSTRACT
Purpose:
The aim of this clinical study was to evaluate the effects of toner, lotion, and cream containing Scenedesmus deserticola JD052 (JD052) extract on UV-induced skin irritation, dermal density, facial wrinkles, and dermal moisture.
Method:
22 female volunteers over 29 years of age were selected on the basis of predetermined inclusion and exclusion criteria. Every morning and night for 4 weeks, each subject washed their face and left upper arm and then applied the same amount of each test material on these areas in the following sequence: toner, lotion, and cream. The following effects were then evaluated: the skin soothing effect on UV-induced skin irritation using a solar simulator and the ANTERA 3D Dermal Imaging Device; dermal density improvement using the DUB®SkinScanner; facial wrinkle improvement using the ANTERA 3D; and dermal moisture improvement using the MoistureMeterD Compact.
Results:
After 2 and 4 weeks, respectively, of application of the test materials, the a* value, which indicated skin redness, was reduced by 5.30% and 5.54%, dermal density was increased by 12.08% and 21.15%, and the wrinkles small value, which indicates the number of skin wrinkles, was decreased by 5.58% and 8.35% compared with pre-treatment levels. Furthermore, dermal moisture was increased by 23.54%, 4.32%, and 6.48% immediately, 2, and 4 weeks, respectively, after application of the test materials compared with pre-treatment levels.
Conclusions:
Toner, lotion, and cream containing JD052 extract were found to have a skin soothing effect on UV-induced skin irritation and to improve dermal density, facial wrinkles, and dermal moisture.
