Ingredient analysis and how the ad lines read

Read on 2026-09-21

What is this product?

A zinc oxide based mineral-leaning sunscreen with 20.752% zinc oxide placed second in the list, plus niacinamide, panthenol and adenosine for soothing and hydrating support. The list contains no added fragrance and no drying alcohol, which suits sensitive skin, though the many esters should be checked against personal tolerances.

What makes it different?

Zinc oxide sits second at a disclosed 20.752%, an unusually transparent figure for a sunscreen. A second UV filter, ethylhexyl methoxycrylene at position 7, works alongside it, so the texture may feel lighter than a pure zinc paste. Niacinamide at position 8, panthenol at 22 and adenosine at 34 add soothing and skin-conditioning support, and 병풀잎소포 is included at a disclosed 1ppm. The list is free of added fragrance and drying alcohol.

Key ingredient

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.
