Ingredient analysis and how the ad lines read

Read on 2026-09-22

What is this product?

A tone-up sun serum built on mineral and organic UV filters with niacinamide at position 9 and ectoin at a disclosed 0.1%, though ectoin itself sits mid-to-late at position 26 of 51. Reasonable to consider for a peach-toned daily sunscreen, less so if you want fragrance-free or high-dose actives.

What makes it different?

The filter system combines titanium dioxide with three organic filters (diethylamino hydroxybenzoyl hexyl benzoate, ethylhexyl triazone, diethylhexyl butamido triazone), all in the top 11 entries. Multiple hyaluronic acid derivatives cluster near the end of the list, alongside aloe, eucalyptus, mint and lemongrass extracts. The disclosed ectoin level of 0.1% is modest, and fragrance is included at position 25.

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: 에틸헥실팔미테이트, 아이소프로필미리스테이트, 폴리글리세릴-3폴리리시놀리에이트, 스테아릭애씨드

Did the ad claims hold up?

We checked the one line this product advertises against the ingredient list and public documents. None of them hold up on their own. They are partly right at best.

Claims translated from Korean, originals preserved.
