Genuine Products & Safety Standards

Home › About › Genuine Products & Safety

Genuine products, correct dosage and safety standards are the principles Yaan Clinic uses to make sure patients receive authentic, properly dosed products from verified sources, delivered with safety tools that reduce complications. At Yaan Clinic in Gangnam, Seoul, several brands can be verified by patients directly, through authenticity cards, serial numbers, QR codes and treatment certificates.

Counterfeit, diluted or under-dosed products are a real risk in aesthetic medicine worldwide. This page explains how Yaan Clinic addresses that risk and what you can check yourself.

What does "genuine products, correct dosage" mean?

It means Yaan Clinic uses authentic products sourced through official channels and injects the dose the treatment plan requires, without diluting or splitting products to cut costs. It is one of the six core commitments the clinic lists for patients.

Yaan Clinic's other stated commitments are dedicated doctors with no substitute practitioners and treatment liability insurance; continuous research and conference activity; 1:1 consultation and analysis; high-quality care; and safety-first treatment.

How can I verify that my products are genuine?

For several brands, Yaan Clinic gives patients a way to check authenticity themselves, such as authenticity cards, serial numbers or digital verification. Ask to see the product or tip before treatment starts.

Which filler and Botox brands does Yaan Clinic use?

For Botox, Yaan Clinic uses Xeomin by MERZ (Germany) and is an Official Key Doctor clinic for MERZ. For fillers, Yaan names Bellast, Restylane, Juvederm and Skin Plus-Hyal, and its doctors are official key doctors for Restylane and Radiesse.

Other brand statuses Yaan states include Juvelook Meister Key Doctor (over 1,000 genuine vials used by 13 March 2025), Skin Plus-Hyal Key Doctor, Silhouette Soft TOP 100 clinic, Alma Elite Club, Oligio Partner Clinic and Elravie Re2O Silver Club. Learn more on the dermal filler and Botox pages.

Why does correct dosage matter?

Under-dosing or diluting a product can give weak or short-lived results, while poor preparation can raise the risk of lumps or uneven results. Correct dosage and preparation help the treatment work as designed.

Yaan Clinic gives concrete examples. Sculptra is prepared with a precise mixing system to prevent clumping, and a full vial is used rather than divided by cc, which Yaan says reduces nodules. Juvelook products are prepared at a controlled temperature and timing to dissolve properly. Thermage FLX shot counts are planned by area, with the full-face tip used for 300–900 shots and the eye tip for 225–450 shots.

What safety tools does Yaan Clinic use?

Yaan Clinic uses blunt cannulas, an infrared vein finder, a patented skin protector, 3D skin analysis and inhaled sedation to make treatments safer and more comfortable.

• Blunt microcannulas – round-ended cannulas that reduce the chance of vessel injury, bruising and swelling during filler.
• AccuVein infrared vein finder – shows blood vessels under the skin before injection.
• Protecter – a skin protector developed and patented by Yaan's medical team, used with fat-dissolving injections to limit irritation and entry-point scarring.
• 3D Meta-Vu analysis – maps pores, wrinkles, texture and pigmentation so energy and dose can be planned by area.
• AirNox – inhaled oxygen and nitrous oxide sedation for pain control.

How can I choose a safe clinic in Korea?

Look for a clinic that names its products, lets you verify authenticity, tells you who will treat you and gives a clear quote before treatment. Ask whether tips are single-use and MFDS-approved, and whether the injector uses cannulas and vessel mapping.
