ROUND LAB Birch Juice Moisturising UV Lock Sunscreen SPF 45 2-Pack — Lightweight Hydrating, No White Cast

This OTC-registered sunblock adapts ROUND LAB's birch juice–based moisturizing formula into an SPF 45, US-compliant product that aims to combine daily protection with a breathable, non-greasy finish. Awarded top ranking in a comprehensive NBC Select sunscreen test, the formula emphasizes hydration and skin comfort, making it a practical choice to wear under makeup or after your skincare routine.

How does this sunscreen fit into my daily skincare routine?

Use this sunscreen as the final step of a morning routine, after serum and moisturizer. Its essence-like texture spreads easily and layers under foundation without pilling, so you can maintain your usual products and still get SPF 45 protection.

• Apply evenly to face and neck as the last skincare step.
• Lightweight formula for easy layering under makeup.
• Non-stinging around the eye area; can be gently patted on lids.

Will it feel heavy or leave a white cast on my skin?

The sunscreen is formulated to be lightweight and non-greasy, absorbing like an essence rather than a thick cream. Users report a natural, skin-like finish without the pale residue that many mineral sunscreens leave behind.

• Essence texture that blends quickly without greasiness.
• Engineered to avoid visible white cast on most skin tones.
• Leaves a smooth base that won’t disrupt makeup application.

Is this safe for sensitive or acne-prone skin?

ROUND LAB designs its formulas to be gentle: this product is free from a list of 19 potentially harmful ingredients, completed low-irritation testing, and holds a German Dermatest certification. The lightweight, non-comedogenic finish helps minimize pore-clogging and irritation concerns.

• Formulated without common irritants and harsh additives.
• Low-irritation testing completed and German Dermatest approved.
• Suitable for a range of skin types, including sensitive and acne-prone.

What protection level and regulatory status does it have?

This product delivers SPF 45 broad-spectrum protection against UVA and UVB rays and is OTC-registered for the U.S. market. That regulatory status means the product meets U.S. sunscreen labeling and performance requirements while keeping the brand’s moisturizing focus.

• SPF 45 offers substantial daily UVB protection for everyday use.
• Broad-spectrum formulation shields skin from UVA and UVB exposure.
• OTC-registered in the U.S., reflecting compliance with local sunscreen rules.

Who is this for: If you want a daily sunscreen that prioritizes moisture, lightweight wear, and a natural finish, the ROUND LAB Birch Juice Moisturizing UV LOCK SPF 45 1+1 (2-pack) is designed for you. It’s particularly suited to people who wear makeup, have sensitive or acne-prone skin, or prefer hydrating textures over heavy creams. The twin-pack format also makes it convenient for home and travel use, or for keeping a backup in your bag.
