GOURI is a collagen stimulator made of liquid PCL (polycaprolactone), an injectable treatment that helps support collagen production in the skin. Kwang Dermatology Clinic Cheongdam has newly introduced GOURI for those concerned about skin elasticity, skin texture, fine lines, and loss of firmness. Options are divided by the number of syringes used: 1 syringe (5cc) treats one area among the butterfly zone, forehead, or jawline; 2 syringes (10cc) treat the butterfly zone plus the forehead or jawline; 3 syringes (15cc) treat the full face; and 4 syringes (20cc) treat the full face and neck. The treatment area and dosage are determined through consultation with the medical staff.
