Test of cytophylaxis against oxidative stress (UV and ROS)

Assess protective effect for various kinds of oxidative stresses at normal human corium fibroblast and normal human epidermal basal cells.
Skin gets stimulated by reactive oxygen species like ultraviolet. This stimulation inflicts oxidative stresses which generate aging. Therefore, searching element which has an effect of protection from oxidative stresses is important for developing anti-wrinkle and anti-sagging products.
