COVERSEOUL BESTIAN SUNSCREEN

Ingredient analysis and how the ad lines read

Read on 2026-09-24

What is this product?

A Korean mineral sunscreen, SPF 50+ PA++++, with zinc oxide as its only UV filter, second in a 61-entry list, and filed as a triple functional cosmetic for UV protection, whitening and wrinkle care (niacinamide and adenosine are listed). Brand test summaries for this sunscreen report SPF 56.2 and UVAPF 16.5 on 10 adults. It has no fragrance entry but does list rosemary leaf oil, plant oils, beeswax and silicones. Its soothing and acne-suitability claims cite small tests that do not name the product, and its non-nano claim has no particle data on the brand pages collected. Suits people who want a mineral-only daily sunscreen.

What makes it different?

A zinc-oxide-only sunscreen that also carries whitening and wrinkle functional filings, with a long botanical and vitamin tail. The protection figures come from product-named SPF and UVAPF test summaries, while the sensitive-skin claims rest on unnamed-sample tests.

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 8 with no dictionary entry, left in Korean.

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.

We could not place these in the list above: 로즈마리잎오일, 카놀라오일, 해바라기씨오일, 프로필헵틸카프릴레이트, 폴리글리세릴-2다이폴리하이드록시스테아레이트

Did the ad claims hold up?
