We do not use any ingredients that are toxic, comedogenic or harmful to your skin. We have blacklisted more than 2000 "toxic" ingredients and base our formulations on factual evidence, using natural botanicals and plant-based actives as our primary formulation. All our products are dermatologist-tested to be hypoallergenic.

Our products are made in Japan.

No, We are Leaping Bunny certified, which means we have passed all the strict international guidelines to not test on animals throughout our supply and production chain. The Leaping Bunny is the most trusted cruelty free certification for non-animal tested products.

We believe skin concerns are more important. Skin types can be too generic; it is possible to have dry and dehydrated skin, yet still suffer from acne. It is also possible for oily skin types to be prone to sensitivity. A generic indication leads to using generic products catered for one generic use. By targeting skin concerns instead, we created custom serums to solve your specific skin concerns. Skin concerns change often due to age, stress, environmental attacks, climate or hormonal changes. We encourage you to be attentive to your skin needs, while we promise to deliver more visible and positive results.
