YŌKI KNOWLEDGE

Ingredient Library

Discover what's inside YŌKI — the ingredients we choose, what they do, and why they belong in our formulas.

OUR APPROACH

Good skincare starts with understanding what's inside it.

We believe skincare shouldn't be mysterious. That's why we want to be transparent about the ingredients in our formulas — from everyday hydration essentials to the Japanese-inspired botanicals that make YŌKI unique.
