A professional Korean corneotherapy line built around one idea: healthy skin starts with a strong barrier.

Instead of aggressively stripping or overstimulating the skin, Corthe works from the outside in. It’s formulas restore, protect, and support the stratum corneum—the skin’s first line of defense. The result is calmer, more resilient, better-functioning skin that can actually hold onto hydration and respond to treatment.

At the heart of the line is CTS™ (Corneotherapeutic System), which delivers human growth factors in liposomes so they can be absorbed more effectively. These help replenish what declines with age, support cell activity, and reinforce the barrier. Around that foundation you’ll find ceramides, centella, niacinamide, peptides, gentle enzymes, and soothing botanicals—medical-grade ingredients chosen for results and comfort.

Corthe is especially well suited for sensitive, reactive, dehydrated, post-treatment, or pigment-prone skin.
