Lindsey Rapp Skin

CORTHE is one of Korea's most respected professional skincare houses — a brand built on decades of dermatological research and a deep understanding of what compromised, sensitive, and demanding skin truly needs. Rooted in the Korean philosophy of barrier-first skin health, CORTHE formulates every product with a single unwavering goal: to restore, protect, and elevate the skin at a cellular level.

What sets CORTHE apart is the brand's commitment to clinical efficacy without clinical harshness. Their Dermo Essential line addresses hydration and barrier repair with signature ingredients like Ceracare H30S — a human skin-identical ceramide complex — and Fucoidan from brown algae, a marine powerhouse that hydrates more deeply than hyaluronic acid and actively supports the skin's regenerative capacity. Their Dermo Pure line targets acne, congestion, and sensitized skin with the same intelligence: actives that correct without stripping, formulations that calm while they clarify.

Every CORTHE product available through Lindsey Rapp Skin has been personally curated and esthetician-approved. This is not a brand that follows trends. It is a brand that follows science — and the results speak for themselves.
