润肤膏 (rùn fū gāo) literally means 'moisturizing skin ointment' — 润 means 'to moisten' or 'to nourish', 肤 means 'skin', and 膏 refers to a thick, semi-solid preparation like an ointment or cream. Together, the term describes a topical product designed to hydrate, soften, and protect the skin. It is commonly used in daily skincare routines, especially in dry climates or during winter.

This word is standard in mainland China and widely understood across Chinese-speaking regions. While it can refer to both medicated and non-medicated creams, it typically implies a thicker, richer formulation than lighter lotions (乳液 rǔyè). You’ll see 润肤膏 on pharmacy shelves, cosmetic packaging, and in medical advice for conditions like eczema or dryness-related irritation.
