numbuzin No.3 Skin Softening Serum

넘버즈인 3번 세럼 · 넘버즈인 3번 스킨 소프트닝 세럼

A high-percentage fermented serum (42% bifida, 21% galactomyces) with niacinamide that smooths rough texture, refines the look of pores, and adds a soft glow.

고함량 발효(바이피다 42%·갈락토미세스 21%)에 나이아신아마이드를 더한 세럼 — 거친 결을 매끈하게, 모공을 정돈하고 부드러운 광채를 더한다.

Best for: Dull, rough, or dehydrated skin that wants fermented hydration and a smoother, glassier finish.

Not for: Anyone sensitive to fermented ingredients, or wanting a rich moisturizer rather than a serum.

이런 사람에게: 발효 보습과 매끈·유리알 마무리를 원하는 칙칙·거친 결·수분부족 피부.

이런 사람에겐 비추: 발효 성분에 예민하거나, 세럼보다 진한 수분크림을 원하는 사람.

What people say [1][3]

Pros and cons reflect recurring themes across retailer reviews; exact counts were not captured.

장단점은 리테일러 리뷰의 반복 주제이며, 정확한 리뷰 수는 미확보.

Pros

  • Smoother texture and a glassy glow for many
  • High fermented content, fragrance-free
  • Great value; layers cleanly
  • 매끈한 결과 유리알 광채 후기 많음
  • 높은 발효 함량, 무향
  • 가성비 좋고 깔끔한 레이어링

Cons

  • Ferments can bother very sensitive skin
  • A serum, not a moisturizer
  • Glow is gradual, not instant
  • 발효 성분이 아주 예민한 피부엔 부담될 수 있음
  • 세럼이지 수분크림은 아님
  • 광채는 점진적, 즉각적이지 않음

Good to know

Ferment-based; patch-test if you react to fermented ingredients. It is a serum step, not a substitute for a moisturizer.

발효 기반이라 발효 성분에 반응하면 패치 테스트를 권한다. 세럼 단계이지 수분크림 대체가 아니다.

Brand claim: numbuzin markets a serum rich in fermented ingredients (bifida, galactomyces) with niacinamide to improve the look of rough texture and complexion while hydrating; it is fragrance-free.

브랜드 주장: 넘버즈인은 발효(바이피다·갈락토미세스)와 나이아신아마이드로 거친 결·안색을 개선하고 보습하는 무향 세럼으로 내세운다.

Independent test data: No independent third-party clinical data confirmed at build time; ingredient percentages are the brand's figures.
