YBK Pore Full Cover Daily Sunscreen

Ingredient analysis and how the ad lines read

Read on 2026-09-23

What is this product?

A Korean tinted mineral sunscreen from YBK, sold as a 50 ml tube from the brand's own storefront and registered as a UV protection functional cosmetic, SPF50+ and PA++++ on the tube. Zinc oxide is second in the list and titanium dioxide twelfth, with no organic filter, in a water in oil base of silicones and synthetic esters. Two iron oxides give it a light olive tint that the brand sells as redness correction and a makeup base. Seven plant extracts, gluconolactone and calamine sit lower in the list without levels. No fragrance entry or essential oil is printed. Oxybenzone and octinoxate are absent. The non nano and no pore clogging statements carry no particle or comedogenicity data, and the no artificial colour icon sits beside two printed iron oxide pigments. A patch test summary is shown but its document is blurred. No pH, water resistance or lived use reports are available.

What makes it different?

The tint is the defining feature: two iron oxides make it a light olive colour corrector rather than a clear or white cast sunscreen, and the brand positions it as a makeup base for flushed skin. Against the brand's own other sunscreen it is the mineral option, sharing only eight supporting entries with that organic formula. Against a landed tinted mineral sunscreen from another brand it shares 21 entries and the same leading order, and differs by the plant extracts, gluconolactone and calamine it adds. Its weakest layer is the claims around the formula: non nano, no pore clogging and no artificial colour are not backed by what the page shows.

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 3 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: 프로필헵틸카프릴레이트, 폴리글리세릴- 2다이폴리하이드록시스테아레이트, 글리세릴카프릴레이트
