Ultracol 100

Ultracol 100 (or UltraCol) is a next-generation, U.S. FDA-registered collagen stimulator (biostimulator) from South Korea, often referred to as “liquid thread” or “melting thread” (PDO). It is designed to rejuvenate skin, increase density, and stimulate collagen production without adding significant volume, making it ideal for treating fine lines, large pores, and skin texture, particularly under the eyes or for acne scars
