The melody of shells that have colored history

OSAJI Makeup Collection Concept
"Colors to accompany you"
Facial features, expressions, presence.
Subtly highlighting that charm.
Light conveys will, color conveys warmth.
Many colors already hide within every person.
Potential waiting to awaken.
Shedding light on inherent individuality, subtly evolving it toward beauty.
OSAJI's approach to makeup is "amplifying charm through accompaniment."
Nuance colors for adults discovering new expressions as extensions of their usual selves.
Because skin and facial features vary in individuality
As life accumulates, expressions reveal how people have lived. OSAJI colors don't cover this individuality but transform it into charm through layering. So that wrinkles born from habitual expressions and dullness brought by age changes become beloved.
Making sensitive skin beautiful
OSAJI is a brand proposing "skincare for sensitive skin." Therefore, we focus on protecting skin moisture and eliminating potential allergens as much as possible when developing makeup products.
