Ultracol is a collagen booster made from PDO (polydioxanone) β the same material long used in surgical sutures β processed into fine micro-particles. Injected into the dermis, it stimulates fibroblasts so your skin produces its own collagen. At Seye Clinic in Gangnam, Seoul, it is performed with a pain-reduced technique.
They differ in particle size and target area. 100 has finer particles and works as a skin booster for texture and firmness; 200 has larger particles for areas needing volume and contour, such as under-eye hollows, deep nasolabial folds and cheek volume loss. Your doctor chooses based on your concern.
The PDO particles break down and are naturally absorbed over about 4β6 months, while newly formed collagen fills in volume and firmness. Unlike filler, it does not create immediate shape: change typically begins around 3β4 days, builds after 4 weeks, and is most visible around 8 weeks. Timing and degree vary by individual.
Usually recommended as 3 or more sessions about one month apart to build collagen gradually, then a touch-up roughly once a year. Building up over several sessions looks more natural than placing a lot at once.
The procedure takes around 30 minutes, performed after topical anesthesia (about 20β30 minutes), with local anesthesia added if needed. You can return to daily life right after; minor swelling or redness usually settles within 1β2 days.
Ultracol pricing depends on type (100/200), area, volume and number of sessions. It is finalized after consultation based on your skin and plan; prices in KRW (USD guide on request). English support is available for international patients.
Suited to those with under-eye or cheek hollowing, deep folds such as nasolabial lines, anyone preferring natural improvement over the look of filler, and those who want to build and maintain collagen over several sessions.

Ultracol (PDO) focuses on collagen stimulation; Rejuran (salmon PN) focuses on regeneration and texture; Juvelook (PDLLA) is also a collagen stimulator; RE2O is HA-based. They differ in ingredient and purpose, so the right choice depends on your concern.
Swelling or bruising can occur at the injection sites and usually settles within a few days. Please tell us in advance if you are pregnant or breastfeeding, or have inflammation at the treatment area. Suitability and dosage are decided after a consultation with the doctor.
