Brand book · v1.1 · Nov 2026
Seoul’s favorite big sister, in a sheet mask.
언니 un·nie, noun big sister; the one you trust.
01
The idea
Some things you ask Mom. Skincare, you ask Unnie. She has tried everything in Seoul, reads ingredient lists for fun, and tells her little sister what’s worth it. Every touchpoint should feel like advice from her.
1
Knows first.
The ingredients Seoul is talking about now: PDRN, rice, ceramides, peptides.
2
Tells it straight.
Plain benefits on the front, a tip on the back. No jargon walls.
3
Keeps it real.
Good ingredients, made in Korea, no splurge required.
Personality
Four words to check every piece against.In the knowSeoul-current, specific about ingredients. Never vague.
Straight-talkingShort sentences. Says what it does and who it’s for.
WarmBig-sister care. On your side, never preachy.
PlayfulWinks, speech bubbles, a little Korean. Fun, not childish.
“The character sells the trial; the ingredient earns the repeat.”The brand’s working rule: Unnie gets you to pick it up, the formula makes you come back.
02
Logo
A hand-lettered retro wordmark with the Korean tagline 언니는 다 알지! (“Unnie knows it all!”). The lettering is custom: never retype it in a font.
Tagline · 언니는 다 알지!
Wordmark · Unnie Wine
Cream keyline
Wordmark · Unnie Wine
Cream keyline
One lockup
Tagline and wordmark always travel together. The tagline sits top-left with its three “spark” strokes.
The keyline is part of it
The cream outline lets the logo sit on any pouch color. Keep it on light and mid-tone backgrounds.
Favicon / tiny sizes
Below the minimum size, use the wordmark-free “언니” seal or a pouch thumbnail instead of shrinking the logo.
Versions
All four come as transparent PNGs in the kit.Full color

The lineup
Four reasons people reach for a mask, one SKU each. Every SKU owns a color, an Unnie moment, a line, and an ingredient pair. Keep those four things locked together.
Dewy
Ceramide + Hyaluronic Acid“So juicy.”
Deep hydration that is still there in the morning.
Glow
Rice + Niacinamide“Lights on.”
Brighter, more even tone. The Seoul rice trick, made real.
Beauty Sleep
Peptide + Ceramide“Do not disturb.”
20 minutes before bed. Wake up looking rested.
07
The pouch
One layout for all four SKUs; only the color, scene, line and ingredients change. From the end of the aisle it should read as a color block with a face.

How Unnie talks
Like a big sister texting you: short, specific, a little teasing, always on your side. She names the ingredient and says what it does. She never oversells.
