The Origin of
Yii
The name "Yii" draws inspiration from the philosophy of change in the *Yi Jing* (Book of Changes).
Life is an ever-flowing cycle of transformation, where moments of ease and challenge shape our journey. By embracing balance and adaptability, we cultivate resilience amid change and maintain serenity through life’s ebbs and flows. This philosophy of thriving through transformation is at the heart of Yii’s skincare vision.

Skincare Philosophy of Yii
Embrace Life’s Changes
Embrace life’s changes, set your own pace, and live with mindfulness. When it comes to skincare, we advocate attuning to the subtle shifts in your skin’s condition, embracing seasonal changes, and harmonizing with environmental transitions. By doing so, your skin can thrive in its natural state, free from constraints, and prepared for any challenge.
“Achieving balance in every skin state, thriving through change”- this is Yii’s skincare philosophy. Yii’s skincare philosophy seeks balance amidst change, fostering resilience and growth. Inspired by the harmony of the four seasons, we focus on addressing your skin’s immediate needs, moving beyond traditional notions of skin type or age. We champion effortless skincare, breaking free from rigid categories and redefining skin minimalism.
Product Philosophy of Yii
Address the Needs of Sensitive, Barrier-Compromised Skin
All Yii skincare products are crafted in Japan, certified as quasi-drugs by the Japanese Ministry of Health, Labour and Welfare, and pass U.S. FDA-standard allergy tests. Formulated for gentleness and safety, they are suitable for use around the delicate eye area and prioritize strengthening the skin’s immune barrier.
With high-potency ingredients and advanced penetration technology, Yii products are designed to address the needs of sensitive, barrier-compromised, and early aging skin.The skin’s barrier function is the key to a radiant complexion and skin vitality. Specifically targeting weak skin barrier concerns, Yii employs Dual-Penetration Technology to deliver highly penetrative emulsions that repair imbalanced cells. Over the skin’s 28-day renewal cycle, our products stimulate cell regeneration, fortify the immune barrier, enhance microcirculation, and restore hydration and oil balance. This transformative process prepares your skin to adapt to seasonal and environmental changes, delivering visible results that reflect Yii’s commitment to radiant, healthy skin.
