This Korean Serum Supports the Skin Barrier
In this video, board‑certified dermatologist Dr. Jane Yoo introduces the Korean skincare brand Demath (Dear My Friends), founded by Regina Choi, and reviews its flagship product, Hero My First Serum. She explains the brand’s focus on skin‑barrier health and accessibility, then details the serum’s unique airy‑foam texture and its blend of botanical oils (macadamia seed oil, jojoba seed oil, evening‑primrose flower extract) that provide lightweight hydration and balance the oil‑moisture ratio. Dr. Yoo highlights the inclusion of low‑molecular‑weight hyaluronic acid (< 500 Da) for deep, lasting moisture, as well as barrier‑supporting actives such as panthenol, ceramide, and allantoin. She notes the fragrance‑ and color‑free formulation, its suitability for sensitive or acne‑prone skin, and the quick‑absorbing, non‑pilling finish that aims to give a “glass‑like” complexion.
