FAQ'S

Is this sunscreen really safe for kids?

Yes! It is officially CPC Certified and clinically proven safe for children aged 6 and older, making it the perfect, irritation-free option for the entire family.

Does it have a strong sunscreen smell?

Not at all. Our formula is completely fragrance-free, meaning no artificial perfumes, no chemical odors, and no stinging eyes.

Will it make my face look oily if I have combination skin?

No. It provides a healthy, hydrated "dewy" finish, but it absorbs completely flat without leaving a greasy film or heavy residue behind.

Is this product authentic? I see other versions online.

Yes, 100% authentic. This is the official OTC Registered version of Round Lab's Birch Juice Sunscreen, specifically compliant with U.S. FDA safety standards. While the packaging might slightly differ from the domestic Korean version, the premium formula is exactly the same authentic, high-quality product.

What is your return policy?

We want you to love your skin. We offer a 30-day money-back guarantee if the product arrives damaged or if you experience any issues. Please refer to our Refund Policy page for more details.

Can I use this if I have highly sensitive or acne-prone skin?

Yes. Our formula is fragrance-free, non-comedogenic (won't clog pores), and clinically tested to be safe, gentle, and soothing even for reactive and breakout-prone skin.
