Take our Skin Ritual Quiz and have your skin needs accessed by our resident dermatologist. Based on your results, have the best suited products reccommended to you.
Inspired by the Japanese Art of Layering and thanks to our Encapsulated BIYUSEN™ Technology, all our serums can be mixed without any contradiction. You can either (1) use the serum alone, (2) layer the serums on different zones of the face, or (3) mix up to three serums in one single step for a customized and targeted treatment.
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.
All our products go through a rigid and complex testing process by our internal R&D team to guarantee visible results and maximum efficacy. To ensure that the active ingredients have the optimal amount for the best efficacy, we recommend mixing up to three serums. Mixing more than three serums in one time would result in having insufficient active ingredients from each serum to have a satisfactory effect.
Please refer to the packaging of the product purchased. The instruction of use can usually be found under the product description. There are certain products that can be used under the eye area.
We reccommend two serums which are best used to address the under eye area: Forever Young Anti-Aging Serum and Skin Reboot Antioxidant Serum.
The Forever Young Anti-Aging Serum helps to lift and tone the eye area, reducing fine lines around the eyes. The Skin Reboot Antioxidant Serum contains caffeine solutions that will synergically work to reduce eye puffiness and improve circulation to lighten dark eye circles.
Results are very personal and depend on many factors, including your own skin genetics. Skin reacts differently and the time taken to see final results would vary for every individual.
In general, thanks to our Encapsulated BIYUSEN™ Technology, which aids in faster visible results, you would find that skin is smoother, calmer and more glowy upon usage. We invite you to wait several weeks (at least two cycles of cell renewal) to see the final effects of the product because a cell renewal lasts up to 4 weeks. The active ingredients contained in the products can be visibly effective on the skin usually after 6 weeks.
