ROUND LAB Birch Mild-Up UVlock SPF 50+ 50ml NPN (HC VERSION) is the brand’s star "mild + high-protection" sunscreen for sensitive skin, with three core advantages:"birch extract soothing & hydrating","SPF 50+ broad-spectrum UV protection", and"HC-compliant safe formula".
1. Core Efficacy: Soothing Protection & Hydration
Broad-Spectrum UV Blocking: Adopts a "physical + chemical hybrid UV filter" (titanium dioxide + ethylhexyl triazone + bis-ethylhexyloxyphenol methoxyphenyl triazine) — effectively blocks both UVB (causes sunburn) and UVA (causes aging/dark spots), with SPF 50+ (UVB protection) and PA++++ equivalent (UVA protection), meeting the high-protection needs of daily outdoor activities and long-term sun exposure.
Birch-Derived Soothing & Hydration: Contains 8000ppm birch sap and birch bark extract — birch sap is rich in amino acids, minerals, and sugars, which replenish skin moisture and enhance barrier function; birch bark extract inhibits inflammatory factors (e.g., IL-6), relieving sun-induced redness and sensitivity.
2. Formula & Texture: Mild & Lightweight
HC-Compliant Safe Formula: The HC VERSION excludes over 20 harmful ingredients banned by Health Canada (e.g., oxybenzone, octinoxate, synthetic fragrances, alcohol) and uses mild preservatives (phenoxyethanol ≤ 0.8%) and natural moisturizers — certified by Health Canada with NPN, ensuring safety for sensitive skin and even post-procedure use.
Weightless Watery Texture: The sunscreen has a transparent, watery liquid texture (no white cast) — spreads smoothly on the skin, absorbs within 30 seconds, and leaves no sticky or greasy residue. It is compatible with all skin types, especially suitable for those who dislike the "heavy, 闷" feeling of traditional sunscreens.
3. Product Design: Practical & Travel-Friendly
Capacity & Packaging: 50ml tube with a flip-top cap — easy to control dosage (1 pump = 0.5ml, enough for the whole face), hygienic (avoids direct contact with air), and suitable for carry-on luggage (meets airline liquid volume restrictions).
Makeup Compatibility: The non-greasy, non-pilling formula can be used as a makeup base — it adheres well to subsequent foundation or cushion, preventing "cakey" makeup caused by heavy sunscreens.
The product breaks the stereotype that "high-protection sunscreens are stimulating" or "mild sunscreens lack protection", positioning itself as "a daily sunscreen for sensitive skin that meets both Canadian regulatory standards and global mild skincare needs".
