ROUND LAB Birch Juice Moisturizing UV LOCK SPF45 Sunscreen 2‑Pack — Lightweight Hydrating, Fragrance‑Free for Sensitive Skin

ROUND LAB Birch Juice Moisturizing UV LOCK SPF45 is a lightweight, lotion-like sunscreen that delivers broad-spectrum UV protection while leaving skin hydrated and free of white cast.

This Korean-formulated sunscreen pairs a moisturizing birch sap base with an oil-free, essence texture designed for everyday wear. Developed as an OTC-registered SPF 45 product for the US market, it preserves the soothing benefits of ROUND LAB’s Birch Juice series while meeting broad-spectrum sun protection standards. The formula is fragrance-free, non-greasy, and made to sit comfortably under makeup without clogging pores.

How will this sunscreen feel on sensitive or acne-prone skin?

The texture is a lightweight, lotion-essence hybrid that absorbs quickly and leaves a natural, non-shiny finish. It’s formulated without common irritants and has passed low-irritation and dermatological assessments for gentle wear.

• Fragrance-free and free from 19 potentially harmful ingredients
• Non-comedogenic texture that won’t clog pores
• German Dermatest certification and low-irritation testing completed

Will I get a white cast or look greasy after applying?

NO — the formula is engineered to avoid a white cast and to blend into various skin tones. It leaves a soft, natural finish that works well as a base under makeup or alone for a subtle glow.

• Essence-like, oil-free consistency that spreads evenly
• Creates a breathable UV barrier without visible residue
• Rated highly in independent testing for finish and comfort

How should I use this SPF 45 sunscreen in my routine?

Apply as the final step of your skincare routine after moisturizer and serums. Pat gently to ensure even coverage over face and neck; reapply every two hours when exposed to sun for continuous protection.

• Use daily as the last skincare step before makeup
• Safe for the eye area; removes easily with regular cleansers
• 2-pack provides an extra tube for travel or backup
