In Japan, we reported Sodium-L-Ascorbic phosphate (AP) had various effects; removal of active oxygen species, normalization of follicular abnormal keratinization, control of sebum output. These effects imply AP is very effective for acne.

The common aspect of these three types is the damage of barrier function. Aitamin derivatives are very helpful for the maintenance of skin homeostasis, and therefore these are to be very effective for the treatmetn of sensitive skin.
