ROUND LAB Birch Juice Mineral Sunscreen SPF 50+ 1.69 oz — Zinc Oxide, Lightweight Hydrating for Sensitive Skin

ROUND LAB Birch Juice Mild-up UV LOCK SPF 50+ is a lightweight mineral sunscreen that provides broad-spectrum zinc-oxide protection while hydrating and calming sensitive skin.

This Korean-formulated face sunscreen pairs high-level mineral sun defense with hydrating birch sap to shield skin from UVA and UVB damage without greasy residue or strong fragrance. Designed for daily wear, it uses non-nano zinc oxide for physical protection, avoids 19 harsh additives, and has been dermatologist-tested for non-comedogenic performance and hypoallergenic safety. The satin, non-greasy finish layers easily under makeup and helps control oil while supporting the skin's moisture barrier.

How does this sunscreen protect sensitive skin?

The product relies on non-nano zinc oxide for physical, broad-spectrum SPF 50+ and PA++++ coverage—reflecting and scattering harmful rays rather than chemical absorption. Because zinc oxide sits on the skin's surface, it minimizes irritation commonly triggered by chemical filters and is appropriate for reactive skin types.

• Mineral-based non-nano zinc oxide SPF 50+ for UVA/UVB defense
• PA++++ rating for enhanced UVA blocking
• Fragrance-free and free from 19 harsh ingredients to reduce sensitivity risk

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

The formula is engineered to be lightweight and non-greasy, blending into skin with a soft satin finish that layers well beneath cosmetics. While mineral sunscreens can sometimes show a white cast, this formulation minimizes that effect and is suitable for everyday layering.

• Light texture that absorbs smoothly without tackiness
• Soft satin finish for makeup-friendly application
• Designed to reduce visible white cast compared with older mineral formulas

How does birch sap benefit my skin in a sunscreen?

Birch sap in the formulation helps deliver lightweight hydration and soothing properties to the skin while supporting the moisture barrier. It complements the physical sunscreen by keeping skin comfortable and less likely to dry or become irritated after sun exposure.

• Hydrates without heaviness to maintain skin balance
• Soothes redness and supports barrier resilience
• Helps reduce dryness that can accompany sun protection products

Is this sunscreen safe and suitable for everyday face use?

Yes—ROUND LAB Mild-up UV LOCK has undergone clinical testing and is labeled dermatologist-tested, non-comedogenic, and hypoallergenic. It excludes parabens, artificial fragrances, mineral oil, and other common irritants, making it a practical daily option for sensitive or reactive skin types seeking mineral protection.

• Dermatest-certified and dermatologist-tested for safety
• Non-comedogenic to avoid pore clogging
• Free of 19 harsh ingredients, including fragrances and parabens

Who is this for: This sunscreen suits people with sensitive, combination, or oily-prone skin who want reliable mineral SPF 50+ protection without greasy residue or strong scents. It's a good pick for those who prefer physical sunscreens, need a makeup-friendly base, or want added hydration from a gentle plant-derived ingredient like birch sap. If you require mineral protection that layers well every day and minimizes irritation, ROUND LAB Birch Juice Mild-up UV LOCK is formulated with those needs in mind.
