InnerSignal is based on the concept of making 40-year-old skin look half its age.

With the idea that activating the energy metabolism of skin cells is the key to youthful skin, Otsuka pursued unique research by examining over 1,000 varieties of plants and yeasts. These efforts were rewarded in 2004, with the development of the active medicated ingredient Energy Signal AMP^*. This was the first ingredient in Japan's skin lightening field to obtain approval for effects and efficacy in suppressing the accumulation of melanin and preventing skin blemishes and freckles.

Preventing accumulation of melanin by stimulating turnover is a natural and positive approach to skin lightening.

Based on study of the process from formation through elimination of melanin, the source of discoloration, medicated brightening extract Sakuraé Double Action Serum inhibits formation of melanin with long-acting vitamin C precursor Ascorbic acid 2-glucoside^*1 and promotes elimination of accumulated melanin with unique Otsuka Pharmaceutical active ingredient AMP^*2.
Through continued use, the repeated Melanin Clear Cycle of inhibition and elimination promotes a clear, translucent complexion.
