Some people notice fatigue showing up on their faces first. In consultations, I often hear that even after a full night's sleep, the area under the eyes looks shadowed, or the cheeks and jawline look more sagging than before. Many people rush to explore fillers without understanding what is causing these changes. Today, we will take a closer look at how Ultracol works and how it differs from regular fillers.

The Root Cause of Facial Sagging: Yongsan Ultracol

Facial sagging and volume loss are not simply the result of losing weight. Beneath the skin, collagen, a protein, forms a mesh-like network that supports the skin from within. As we age, collagen production naturally declines. As a result, skin elasticity and structural support both weaken, leading to sagging and hollowing at the same time.

Fillers and Ultracol Work Differently: Yongsan Ultracol

Many people think of Ultracol as just another type of filler, but its actual mechanism is different. Standard hyaluronic acid fillers physically fill space by injecting a gel into hollowed areas.

The PDO (polydioxanone) used in Ultracol works by stimulating fibroblasts in the skin, helping the body produce collagen on its own. Research has also reported that PDO stimulates fibroblasts to induce collagen production. PDO is also a material that has long been used in surgical sutures, and it has the property of being naturally broken down by the body over time.

Ultracol is recommended for those wanting natural volume or a simple procedure, or bothered by fading elasticity, wrinkles or dull skin.
Consider a Consultation If These Apply: Yongsan Ultracol

Under-eyes or cheeks that have gradually hollowed out and developed shadows

Discomfort with the artificial look after filler treatments

Preferring natural-looking change over immediate volume

Concern about reduced firmness along the jawline or cheek contour

That said, the degree and causes of these changes vary depending on individual skin condition and the pace of aging. Rather than self-diagnosing, it is essential to first confirm your current condition accurately through a consultation with a specialist.

What to Know Before Treatment: Yongsan Ultracol

Because Ultracol works by stimulating collagen production, results do not appear immediately, and the speed and extent of change can vary depending on each person's skin response. Temporary swelling or bruising may occur depending on the treatment area. Thin-skinned areas such as under the eyes, in particular, may see different outcomes depending on the amount injected and the injection site, so precise assessment is important. Before treatment, be sure to tell your medical team about any medications you are currently taking and any allergy history to ensure a safe procedure.

Frequently Asked Questions: Yongsan Ultracol

Q. Are results visible right after an Ultracol treatment?

Unlike fillers, which provide immediate volume, Ultracol stimulates collagen production, so changes appear gradually. Results vary from person to person, but many people notice gradual improvement over several weeks.

Q. Can it be combined with fillers?

Whether the two can be combined depends on your skin condition and desired results, so it is best to discuss a plan tailored to you during a consultation.

Q. How much pain is involved, and how long is the recovery period?

This depends on the treatment area and individual skin sensitivity, but swelling and bruising usually subside within a few days.

Q. Can thin areas like under the eyes be treated?

Yes, but because the skin is thin, the amount injected and the placement must be carefully determined, and checking left-right balance meticulously is important.

Q. How often should treatments be done?

The recommended interval may vary depending on the speed of collagen production and the degree of aging, so it is best to check during regular consultations.
