ROUND LAB Birch Juice Mineral Sunscreen SPF 50+ 1.69 fl oz — Non‑Nano Zinc Oxide, Lightweight Hydration

ROUND LAB Birch Juice Mild-up UV LOCK SPF 50+ is a mineral facial sunscreen that uses non-nano zinc oxide for broad-spectrum protection while keeping skin hydrated and comfortable.

This Korean-formulated sunscreen combines physical UV filtering with birch sap to deliver high-level UV defense without heavy residue or added fragrance. Designed for daily use on sensitive and combination skin, it sits well under makeup, controls excess oil, and aims to soothe the skin barrier while avoiding common irritants. Clinical testing and a clean-ingredient approach make it a solid option for those who prefer mineral sunscreens but dislike chalky textures.

How does this sunscreen protect my skin from sun damage?

ROUND LAB’s formula relies on non-nano zinc oxide to reflect and scatter UVA and UVB rays, offering broad-spectrum SPF 50+ coverage. Zinc oxide is a physical blocker that sits on the skin surface rather than being absorbed, making it a popular choice for sensitive skin types.

• Mineral-based protection with non-nano zinc oxide for physical UV defense
• High SPF 50+ and PA++++ level for strong UVA/UVB coverage
• Broad-spectrum performance suitable for daily outdoor exposure
• Fragrance-free to reduce potential irritation from added scents

Will it feel heavy or leave a white cast under makeup?

The texture is formulated to be lightweight and non-greasy, absorbing into the skin with a soft satin finish that layers well under foundation. While mineral sunscreens can sometimes leave a faint cast, this product is engineered to minimize that effect on most skin tones.

• Light, fast-absorbing consistency that blends smoothly
• Leaves a natural satin finish suitable for makeup application
• Designed to reduce the typical white cast of mineral sunscreens
• Oil-control properties help reduce midday shine on combination skin

How does the birch sap help my skin while wearing sunscreen?

Infused birch sap provides lightweight hydration and supports the skin’s moisture barrier so sunscreen won’t feel drying over time. The moisturizing component helps soothe and maintain comfort, particularly for those with sensitive or dehydrated skin.

• Birch sap delivers mild, fast-absorbing hydration
• Helps reinforce the skin’s moisture barrier during sun exposure
• Complements mineral UV filters without heavy occlusion
• Non-irritating, fragrance-free formula suitable for reactive skin

Is this product safe for sensitive or acne-prone skin?

ROUND LAB’s sunscreen is formulated without common harsh additives and has undergone dermatological testing, making it appropriate for many sensitive and acne-prone users. It’s non-comedogenic and free from parabens, artificial fragrances, and mineral oil to limit pore-clogging and irritation risks.

• Free of 19 harsh ingredients like parabens and artificial fragrances
• Dermatologist-tested, hypoallergenic, and non-comedogenic
• German Dermatest certification supporting safety claims
• Suitable as a daily face sunscreen for sensitive skin types
