Star Ingredients

This sunscreen is powered by nature and perfected by science:

• Birch Sap: Sourced from the Silver Birch trees of Inje, Korea, this nutrient-rich sap deeply hydrates and purifies the skin with its cocktail of minerals and amino acids.
• Niacinamide: A true multitasker, it helps brighten skin, reduce the look of pores, and improve your skin’s overall health.
• Hyaluronic Acid: This moisture magnet pulls water into the skin, locking in hydration for a plump, smooth look all day long.

How to Use

1. Complete your morning skincare routine (cleanser, toner, serum, moisturizer).
2. As the final step, dispense a generous amount of sunscreen. A good measure is the ‘two-finger rule’—squeeze a line of product onto your index and middle fingers.
3. Gently apply to your face, neck, and any other areas exposed to the sun.
4. Pat it in until fully absorbed. Wait about 15 minutes before sun exposure.
5. Frequency: Use every single morning, rain or shine! Reapply every 2 hours if you’re outdoors.

Expert Tips & Tricks

• The Perfect Pair: Apply this sunscreen over your favorite Vitamin C serum in the morning. Vitamin C provides antioxidant protection that enhances your SPF’s ability to fight sun damage.
• Retinol Routine Must-Have: Using a retinoid at night? This sunscreen is your non-negotiable morning essential to protect newly sensitive skin.
• Pro Tip: Don’t forget your ears, the back of your neck, and your hands! These areas show signs of aging too and need daily protection.

Q&A: Your Questions, Answered

Is the Round Lab Birch Sunscreen good for oily or acne-prone skin?

Yes! Its lightweight, non-comedogenic formula feels more like a hydrating essence than a heavy cream. It absorbs quickly without clogging pores or feeling greasy, making it a favorite even for those with oily and acne-prone skin types.

Does this sunscreen leave a white cast?

Absolutely not. As a chemical sunscreen, it uses modern UV filters that absorb invisibly into the skin. It’s designed to be completely transparent on all skin tones, from the very fairest to the very deepest, leaving only a fresh, dewy finish.
