What is this product?

Dear Klairs' All Day Airy mineral sunscreen is a zinc-only SPF50+ PA++++ cream sold in 35g and 60g. 징크옥사이드 at position 2 is the sole UV filter across 33 items with no organic filter present, which makes the 무기자차 label exact. The statutory block on the brand's own page files two functions, UV protection and whitening, with 나이아신아마이드 at 9 matching the second; wrinkle improvement and tone-up are not filed. A real barrier block sits from position 20 down: ectoin, panthenol, ceramide NP, phytosphingosine, tocopherol, all at undisclosed levels. The finish is set-down and dry, built from isododecane at 8 and polymer spheres at 17 and 22. No fragrance entry, no alcohol. SPF50+ and PA++++ appear in brand-published product naming but not in any statutory row, and four named tests (human application, eye irritation, primary irritation, non-comedogenic) carry no institution, panel size or date. Press wording claims both no white cast and a tone-up effect for the same mineral layer.

What makes it different?

Three things separate it from neighbouring mineral sunscreens. First, the filter list is inorganic without hedging: one zinc entry and not a single organic filter across 33 items, where many products carrying the 무기자차 label still include an organic booster. Second, the barrier block is unusually complete for a sunscreen, pairing ceramide NP with phytosphingosine and ectoin rather than the single token humectant the category usually offers, though all of it sits below position 20 at undisclosed levels. Third, it is a clean worked example of the gap between a filed function and a marketed one: the statutory row files UV protection and whitening, while the press material sells tone-up and no-white-cast, two claims that describe the same optical property of zinc with opposite valence.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

This brand publishes its ingredient list in Korean only. Names below are the matching INCI names from the Korean Cosmetic Association ingredient dictionary, except 2 with no dictionary entry, left in Korean.

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

We could not place these in the list above: 프로필헵틸카프릴레이트, 세틸에틸헥사노에이트, 하이드로제네이티드코코넛오일, 트라이에틸헥사노인, 폴리글리세릴-6폴리리시놀리에이트, 폴리글리세릴-2다이폴리하이드록시스테아레이트, 글리세릴카프릴레이트, 드럼스틱씨오일
