YBK Pore Clear Clay Cream Mask

What is this product?

A Korean wash-off clay cream mask from YBK, sold as a 200 ml tub from the brand's own storefront. Four clays, kaolin and bentonite high in the list with illite and montmorillonite low, sit in a glycerin led base that is designed to stay wet rather than set hard. Gluconolactone, a polyhydroxy acid, is the one exfoliating entry, at an undisclosed level. Seven plant extracts, led by houttuynia, and calendula under its statutory name, sit in the middle of the list. No fragrance entry or essential oil is printed. The copy's ten percent houttuynia and two percent calendula figures are not on the statutory list, cooling is claimed with no cooling agent, and two iron oxide pigments sit beside a no artificial colour icon. A patch test caption is shared with the brand's sunscreen page. No pH or lived use reports are available.

What makes it different?

A cream type clay mask that stays wet: humectants lead the list ahead of four clays, and two mild nonionic surfactants help it rinse. It adds one gentle exfoliating acid, gluconolactone, but at an undisclosed level in a ten minute rinse off. Against a landed clay pore pack from another brand it shares the same four clays but carries no mint, so its cooling claim rests on evaporation rather than on an ingredient. Its weakest layer is the numbers in the copy, which the statutory list does not back.

We checked 25 lines this product advertises against the ingredient list and public documents. One of them holds up. The rest are only partly right or have nothing behind them.
