Why we start with pH
pH is one of the fundamental indicators for understanding cleansing behavior and design direction. On this site we publish measured pH values and use them as a basis for multi-faceted analysis.
Our evaluation criteria and commitment to independence.

Evaluation Policy
— As reference for choosing cleansers —
Cleansers are products we use every day, yet there are few opportunities for formulation characteristics to be shared in an organized way. At the same time, factors such as pH and ingredient design do relate to product performance. This platform aims to create an environment where such information can be organized and checked.

Evaluation and analysis are carried out according to criteria independent of any specific company or seller. Some pages include affiliate links, but our evaluation criteria and analysis content are separate from revenue.
We do not judge which products are better or worse. We provide reference material to help you understand product characteristics when considering a purchase.
A reliable source you can refer to when choosing a cleanser. That is the position we aim to hold.
