Round Lab Birch Moisture Sun Cushion

What is this product?

A reasonable pick when the requirement is a mineral-only SPF50+ filter in a cushion that can be patted over makeup, and a poor one when a cooling effect is the reason for buying. Zinc oxide at position 2 and titanium dioxide at position 5 of 40 declared entries carry the protection, with no organic filter present, and the hydration side rests on propanediol, glycerin, glyceryl glucoside, two hyaluronic forms, and birch sap disclosed at 1,045ppm. The SPF50+/PA++++ designation is graded supported because the Korean functional-cosmetic filing behind it is on record for the matching Olive Young goods number, though no test report is published. No fragrance and no drying alcohol are declared.

What makes it different?

Two things set it apart on the spec sheet. It is a mineral-only sunscreen in cushion form, which is an unusual pairing because inorganic powder is harder to keep dispersed in a compact than organic filters are, and the ester-heavy oil phase visible in the list is the price paid for that. Second, the signature botanical carries a printed concentration, 자작나무수액 at 1,045ppm, a figure the panel was under no obligation to print. The brand's own product page is image-only, so every claim graded here had to be traced to a payload or a retailer listing rather than to brand prose.
