Ultracol
A PDO collagen booster hydrated separately for each patient

Ultracol is a treatment that injects a collagen booster made from fine particles of PDO (polydioxanone). PDO is a material that has long been used in medical sutures and other applications. It is used to improve skin firmness, density, fine lines, and shallow hollows over time.

The principle is that while the injected PDO particles gradually break down in the body, they induce collagen formation in the surrounding tissue. The injected material does not create volume right away, so change appears gradually over time. The degree of change varies by individual depending on skin condition.

Yes, it can be used on thin-skinned areas such as under the eyes or the forehead. However, these areas have delicate anatomy, so the concentration and injection layer are chosen with extra precision. Under-eye hollowing has various causes, so depending on the cause, another approach such as filler or lifting may be more suitable.

We consider it for those whose skin has become thinner and less firm, or who are concerned about fine lines and subtle hollowing in shallow areas. Conversely, if you want clear volume change right after injection, or the area needs defined shape such as the nose or chin, filler may be more suitable. We decide together after checking skin thickness and the cause of hollowing at consultation.

As a rule, Ultracol is not mixed just before treatment; it is prepared through a thorough hydration process. Once your booking is confirmed, we record the patient's name and the hydration start date and begin hydrating that vial in advance. The prepared product is used exclusively for that patient, and even if the treatment does not take place, it is discarded rather than used for another patient.

There is an injection sensation, so topical numbing cream is applied beforehand to reduce discomfort. Treatment time depends on the area and coverage and is advised at your visit. How it feels varies by area and individual sensitivity.

Injection marks or slight swelling and bruising may appear, and they usually settle within a few days. For 24 hours after treatment, do not rub or press the injection sites, and avoid alcohol, strenuous exercise, and saunas on the day of treatment. We recommend waiting 2 weeks before massage or intensive skin treatments, and please contact us right away if pain worsens or you notice unexpected changes.

Because collagen formation takes time, many people notice change as time passes rather than right after treatment. When change appears and how long it lasts depend on the area, number of sessions, and skin condition, and are advised at your visit. How long results last also varies by individual depending on lifestyle.

The number of sessions and intervals needed are decided after consultation based on skin thickness, your goal, and progress after 1 session. Rather than judging change from a single session, we adjust the plan while checking progress. We also advise on the timing of care after completing the sessions.

Both are boosters that induce collagen formation, but their ingredients differ: PDO (Ultracol) and PDLLA (Juvelook Volume). Grays Dermatology performs collagen boosters mainly with these two, choosing one or planning both together depending on the area, skin thickness, and degree of hollowing. Which approach suits you is advised after consultation.

Along with bruising and swelling at the injection site, adverse reactions such as lumps (nodules) may rarely occur, so a board-certified dermatologist injects directly, following the set preparation process and injection method. Be sure to tell us at your visit if you are pregnant or breastfeeding, taking anticoagulants, or have ever had a hypersensitivity reaction to the product's ingredients. Treatment may be postponed if there is inflammation or infection at the injection site.

The cost depends on the area, volume, and number of sessions, and is confirmed after consultation; reference prices can be found on the price list on our website. Because Ultracol requires hydration preparation for each patient, same-day treatment is difficult and booking at least 5 days in advance is required.
