Eyebrows are one of the fastest ways to shift a person’s “vibe” without changing anything else—because they subtly reframe the eyes, lift (or soften) the face, and control how sharp or gentle the overall impression feels. A recent Korean beauty feature compared Jang Wonyoung and aespa’s NingNing as two clear references for today’s brow split: soft straight vs. soft semi-arch.

Jang Wonyoung: “Soft Straight” Brows for a warmer, gentler impression

The article notes Wonyoung previously leaned more semi-arch, but recently shows a more natural straight brow—not the old, rigid straight-brow trend. Instead, the brow peak isn’t erased completely; the tail is slightly lowered and cleaned up, creating a softer, younger, more approachable mood.

Mood effect: softer atmosphere, warmer impression, “gentle but polished.”

NingNing: A “Semi-Arch” Brow for refined, lifted energy

NingNing is described as wearing an understated semi-arch—a smooth curve without an exaggerated peak. That gentle lift naturally pulls the gaze upward and adds a more “refined” edge to her visuals. The article also points out a gradient-like density (lighter at the front, more defined toward the tail) to keep it from looking too harsh. Mood effect: cleaner definition around the eyes, more sleek and sophisticated “sharpness” without being aggressive.

What brow shape changes visually

• Straight-leaning brows: visually soften angles and make the face read younger, calmer, warmer.
• Semi-arch brows: add dimension and lift, making the eyes look more defined and the face feel more structured.

If you’re deciding “straight or arch,” Wonyoung and NingNing are strong reference points: straight for gentle warmth, semi-arch for refined lift—two different moods driven primarily by brow geometry.
