ROUND LAB Birch Juice Moisturizing Sun Cream SPF50+ PA++++

라운드랩 자작나무 선크림 · 라운드랩 자작나무 수분 선크림 SPF50+ PA++++

A moisturizing chemical sunscreen built on birch juice with hyaluronic acid and niacinamide — high protection, a hydrating finish, and little to no white cast.

자작나무 수액에 히알루론산·나이아신아마이드를 더한 수분 화학 선크림 — 높은 차단, 촉촉한 마무리, 백탁 거의 없음.

Best for: Normal to dry or combination skin wanting a hydrating daily sunscreen without a heavy or greasy feel.

Not for: Those who prefer a matte finish or who react to chemical UV filters.

이런 사람에게: 무겁거나 번들거리지 않는 촉촉한 데일리 선크림을 원하는 보통·건성·복합 피부.

이런 사람에겐 비추: 매트한 마무리를 원하거나 화학 자외선 필터에 반응하는 사람.

What people say [1]

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

장단점은 리테일러 리뷰의 반복 주제이며, 정확한 리뷰 수는 미확보.

Pros

  • Little to no white cast
  • Layers well under makeup
  • 촉촉하고 편안한 데일리 마무리
  • 백탁이 거의 없음

Cons

  • Moisturizing finish is less ideal for very oily skin
  • Chemical filters may not suit reactive skin
  • 50 ml runs out quickly with proper reapplication
  • 촉촉한 마무리라 지성엔 다소 부담
  • 화학 필터가 예민 피부엔 안 맞을 수 있음
  • 제대로 덧바르면 50ml가 금방 소진

Good to know

It uses chemical UV filters; patch-test if your skin reacts to sunscreens. Reapplication matters more than the SPF number on the label.

화학 자외선 필터를 쓴다 — 선크림에 반응하는 피부라면 패치 테스트를 권한다. 표기 SPF 숫자보다 덧바르는 습관이 더 중요하다.

Brand claim: ROUND LAB positions it as a moisturizing sunscreen built on birch juice with hyaluronic acid to protect and hydrate in a lightweight, quick-absorbing, no-white-cast formula.

브랜드 주장: 라운드랩은 자작나무 수액과 히알루론산으로 보호·보습하는 가볍고 빠른 흡수·무백탁 수분 선크림으로 내세운다.
