Questions,Answered.

Everything you need to know before you get started.

InnerSignal is a Japanese skincare brand developed by Otsuka Pharmaceutical Co., Ltd., designed to support healthy, youthful looking skin through science-backed skincare innovation.

InnerSignal focuses on skin health as the foundation of lasting beauty. Rather than targeting a single concern, the serum is designed to support multiple visible signs of skin aging, including dryness, dullness, uneven tone, and the appearance of fine lines.

AMP (adenosine monophosphate) is a naturally occurring molecule found throughout the body and plays an important role in cellular energy processes.

InnerSignal is suitable for all skin types, including dry, normal, combination, and mature skin. The formula is tested on sensitive skin as well.

Yes. The development of InnerSignal is supported by scientific research conducted by Otsuka and its research teams in Japan.
