FAQs About ROUND LAB Birch Juice Moisturizing Sunscreen:
- Is ROUND LAB Birch Juice Moisturizing Sunscreen good?
Yes, the Birch Juice Moisturizing Sunscreen is considered one of the best daily facial sunscreens available. Beauty editors, skin care enthusiasts and dermatologists often praise the formula for its cosmetic elegance and overall performance.
For example, in a six-month trial conducted by NBC Select editors in 2025, the Birch Juice Moisturizing Sunscreen was tested alongside 110 other facial SPFs. It ranked #1 overall thanks to its invisible finish, lack of pilling and impressive compatibility with a wide range of skin tones.
This ROUND LAB sunscreen is also backed by clinical testing from the Korea Institute of Dermatological Sciences. Results showed an average SPF rating of 55.0, slightly exceeding its labeled SPF 50+ protection. The formula also achieved a UVA Protection Factor (PFA) of 19.80, meeting the highest PA++++ standard for UVA protection.
- Is ROUND LAB Birch Juice Moisturizing Sunscreen mineral or chemical?
The ROUND LAB Birch Juice Moisturizing Sunscreen is a chemical sunscreen. However, the brand also offers a mineral version, Birch Juice Moisturizing Mild Up Sunscreen, which is designed to be extra gentle on skin.
- Is ROUND LAB Birch Juice Moisturizing Sunscreen waterproof?
No, the Birch Juice Moisturizing Sunscreen is not waterproof or water-resistant. It’s designed for every day, urban wear rather than intense water or sports exposure. For best protection, reapply at least every two hours, and more frequently if you’re swimming, sweating or spending extended time outdoors.
- Is ROUND LAB Birch Juice Moisturizing Sunscreen safe for sensitive skin?
Yes, the Birch Juice Moisturizing Sunscreen is suitable for sensitive skin. It has been clinically tested for skin irritation by the Global Medical Research Center; after a 24-hour assessment, results verified that the ROUND LAB sunscreen is a low-irritation product.
Even better, the formula is packed with soothing ingredients like dipotassium glycyrrhizate, allantoin and portulaca oleracea extract. These actives calm and comfort skin that may feel stressed or sensitized from UV exposure.
