• 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".

UV Protection Core:
Titanium Dioxide (physical UV filter, blocks UVB/UVA, mild, no skin penetration);
Ethylhexyl Triazone (chemical UV filter, high-efficiency UVB blocker, low irritation);
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (chemical UV filter, broad-spectrum UVA/UVB blocker, stable in sunlight).
Soothing & Hydrating Core:
Birch Sap (8000ppm, rich in amino acids, minerals, sugars — replenishes moisture, strengthens barrier);
Birch Bark Extract (contains betulinic acid — inhibits inflammation, relieves sun-induced redness);
Sodium Hyaluronate (small-molecule hyaluronic acid — deep hydration, reduces dryness);
Glycerin (natural humectant — attracts environmental moisture, maintains skin hydration).
Mild Stabilizers & Preservatives:
Phenoxyethanol (mild preservative, ≤0.8% concentration, compliant with Health Canada standards — prevents microbial growth);
Xanthan Gum (natural thickener — adjusts texture, no irritation);
Disodium EDTA (chelating agent — stabilizes formula, enhances ingredient efficacy).
Safe Base:
Free of alcohol, synthetic fragrances, parabens, oxybenzone, octinoxate, mineral oil, and artificial colorants;
All ingredients are listed in Health Canada’s Natural Health Products Ingredients Database (NHPID), ensuring compliance with local regulations and suitability for sensitive skin.

Pre-Use Preparation: Complete basic skincare (cleanser → toner → serum → moisturizer) and wait 5-10 minutes until the moisturizer is fully absorbed — applying sunscreen on damp skin may cause pilling.
Dispense the Sunscreen: Open the flip-top cap, press 1 pump (about 0.5ml) of sunscreen onto the palm of your hand (increase to 1.5 pumps for the face + neck to ensure even coverage).
Apply Evenly:
Gently spread the sunscreen over the entire face with your fingertips, starting from the center (nose, cheeks) and moving outward (forehead, jawline). Avoid the eye area (use a dedicated eye sunscreen if needed) and lip contour (apply lipstick or lip balm afterward).
Extend the application to the neck, earlobes, and the back of the hands (areas often exposed to UV rays but easily overlooked) to prevent uneven tanning or aging.
Wait for Absorption: Wait 10-15 minutes until the sunscreen forms a protective film before applying makeup or going outdoors — this ensures optimal UV protection efficacy (unabsorbed sunscreen may rub off or reduce protection).
Reapply Regularly: Reapply every 2 hours when outdoors (especially during sweating or swimming, as water-resistant properties may weaken over time). For indoor use, reapply every 4 hours if near windows (UVA can penetrate glass).
Note: Do not remove sunscreen with just water — use a mild cleanser (foaming or oil cleanser) to ensure thorough removal, avoiding clogged pores.
