Verifying Genuine Botox and Filler Before Treatment 2015.06.29

Check the Product and the Doctor First: Dr. Wontak Choi on Genuine Botox and Filler

Inquiries about aesthetic procedures climb every year when the summer holiday season starts, and Botox and filler lead the list. Yaan Clinic in Gangnam, Seoul, was featured in a Korean news article that used these two treatments to explain why product authenticity matters. The article quoted Dr. Wontak Choi, the clinic’s representative director, who is described as a Seoul National University graduate with teaching experience and a past post as clinical instructor at an obesity clinic.

All treatments at Yaan Clinic are performed by a skilled, specialized medical team, delivering standardized, high-quality care based on the clinic's own proven clinical protocols.

Why the product matters

The article points out that both treatments rely on drugs, so the type of product, whether it is genuine, and the skill of the injector all affect the outcome. Botox is described as a way to soften facial lines and, in recent years, to reduce an overdeveloped jaw muscle and shape a V-line jaw. Its effect generally lasts six months to a year, depending on the person’s muscle development.

Both treatments have little downtime. Because no incision is needed, the report says aftereffects are limited and concern about swelling or pain is low.

What Dr. Choi advises

Before treatment, Dr. Choi recommends asking three questions:

• Is the product genuine?
• Which drug will actually be used?
• How much treatment experience does the medical team have?

He also advises patients to look for a clinic that can explain these points in detail.

Both treatments are suited to the holiday period because patients can return to daily life afterward. The article notes that Botox for the jaw is injected into the chewing muscle in several places, and that, unlike surgery that shaves the jawbone, it leaves no scar. Jawbone surgery, by comparison, can cause heavy swelling for two weeks to a month, which keeps patients away from daily activities.
