YBK Ceramide Relief Hydration Emulsion
Ingredient analysis and how the ad lines read

What is this product?
Reach for this 120ml pump emulsion if the goal is water and lipids on skin that is dehydrated, reactive or barrier-tired: the lotion step is where it belongs, after a toner and under a cream. Two things make the case. The lipid deck is the full lamellar set, five ceramides plus cholesterol and phytosphingosine, which is rare at this list length, and the soothing side runs on centella printed first ahead of water at a self-reported 79.9 percent, with all four centella acids listed separately. A brand-published 30-subject primary irritation study reported an index of 0.0, and the 46-item list names no fragrance, no drying alcohol and no exfoliating acid. Skip it for shine control: nothing in the formula acts on sebum, and the page's oil-balance promise reduces to a dosing instruction. Skip it too if flaking dryness needs sealing, since the formula holds water but forms no film. pH and an English INCI list are not published, and the brand's EWG green and only-efficacy-ingredients wording is self-assigned and contradicted by its own list.
What makes it different?
Two things separate it inside the Korean lotion-step field. It prints centella extract ahead of purified water and then lists all four centella acids and all five stratum corneum ceramides plus cholesterol and phytosphingosine as separate entries, so the soothing and barrier stories are both carried by named molecules rather than by one extract doing double duty. And it is built around a dosing instruction rather than a fixed application: one, two or three pumps by skin condition, which is unusually concrete advice on a page whose other promises are not.
