CORTHE is a professional Korean barrier-focused cosmeceutical brand developed according to the principles of corneotherapy — a scientific approach to restoring and maintaining a healthy skin barrier.

The name CORTHE is derived from the words corneocyte and therapy. The brand’s philosophy focuses on restoring the structure and function of the stratum corneum rather than addressing visible skin concerns alone.

The CORTHE system follows a structured treatment sequence:

• gentle two-step cleansing without drying the skin;

• controlled enzymatic exfoliation;

• targeted professional serums;

• soothing masks for manual and device-assisted procedures;

• lamellar products for barrier restoration and moisture retention;

• a protective, glow-enhancing finish.

Professional protocols are complemented by home care for sensitive, reactive, dehydrated and damaged skin, as well as skin with rosacea, excessive oiliness and breakouts. The range includes products containing centella, probiotics, peptides, amino acids, fucoidan and sebum-regulating ingredients.

CORTHE does not replace active cosmetology. A healthy, resilient skin barrier helps the skin tolerate professional treatments, recover more quickly and maintain the results achieved.
