ROUND LAB Birch Juice Moisturizing UV Lock Sunscreen SPF 45 1.69 fl oz — Hydrating, Lightweight, Fragrance-Free

ROUND LAB Birch Juice Moisturizing UV LOCK SPF 45 is a lightweight, lotion-like Korean sunscreen that delivers broad-spectrum UV protection while hydrating without leaving a white cast.

Designed to combine everyday sun protection with a moisturizing finish, this OTC-registered SPF 45 formula adapts the brand’s popular birch-juice moisture complex into a breathable, non-greasy sun protector. It’s fragrance-free, formulated for sensitive and acne-prone skin, and clinically evaluated for low irritation—making it a practical daily sunscreen for under makeup or a no-fuss morning routine.

How does this sunscreen feel on the skin?

The texture is a lightweight essence-lotion that absorbs quickly and leaves a natural, slightly dewy finish rather than a heavy film. It won’t feel greasy or tacky, which helps it layer well under primers and foundations.

• Essence-like, lotion finish for easy spreading
• Non-greasy and breathable for all-day wear
• No white cast—suitable for a range of skin tones

Will it irritate sensitive or acne-prone skin?

ROUND LAB formulates this sunscreen to avoid common irritants and excludes 19 harmful ingredients, aiming to minimize reactions. It has completed low-irritation testing and holds German Dermatest certification, so many users with sensitive or blemish-prone skin find it gentle.

• Fragrance-free and low-irritant formulation
• Non-comedogenic texture that won’t clog pores
• Dermatest-certified and clinically evaluated for sensitivity

How do I use it within my skincare routine?

Apply this sunscreen as the final daytime skincare step after serum and moisturizer. Use a generous, even layer across face and neck; reapply every two hours when exposed to sun for sustained protection.

• Finish with sunscreen after moisturizer and makeup prep
• Gently pat into the delicate eye area—non-stinging formula
• Removes easily with regular cleansing at the end of the day

What practical benefits will I notice day-to-day?

Beyond UV defense, the birch-juice inspired formula offers lightweight hydration that helps skin look smoother and more even under makeup. Its no-white-cast finish and quick absorption reduce the need for waiting time when layering cosmetics.

• Hydrating finish that supports makeup application
• Quick-absorbing texture for busy mornings
• OTC-registered SPF 45 broad-spectrum coverage for daily use

Who is this for: This sunscreen suits anyone seeking reliable daily SPF with a hydrating, non-greasy feel—especially those with sensitive, acne-prone, or combination skin who prefer fragrance-free, clinically tested K-beauty formulations. It’s ideal for people who want a makeup-friendly, no-white-cast protector they can apply quickly each morning and reapply when spending time outdoors.
