One Thing is a South Korean skincare brand built around transparency and minimalism. Its products focus on a single key ingredient at a time, so users can clearly understand what theyโre applying and tailor routines more easily.
The range includes toners, essences, creams and serums, each centred on one primary plant or fruit extract such as Centella Asiatica, Hibiscus Sabdariffa Flower, and Artemisia Capillaris. Their single-ingredient approach is designed to reduce unnecessary additives and make an ingredient selection with a clear highlight.
The brand was developed in response to growing consumer demand for clearer ingredient lists and simpler formulations, and it also emphasises sustainability in its product approach.
