Y&Y MEDICAL · Seoul, Korea

We provide education. The product comes with it.

Y&Y MEDICAL is not a trading company. We work with one Korean brand, lēfilleo, and one core product, INFUSKIN. We bring it to new countries with its registration, and we train the doctors who use it. The training is the part we care about most.

How we work

One brand

One brand, one core product

Not a catalog of whatever sells this season. lēfilleo is the brand and INFUSKIN is the product we put everything behind: registration, training and the films you see here. The rest of the range follows it.

Education

Nothing ships without training

Every product we distribute comes with training from a dermatologist who uses it. A doctor who has learned the technique is the result we measure, so the academy is where our time goes first.

Territory

One distributor per country

The partner who invests in registration and training keeps the market. We do not appoint a second distributor in the same country, and we do not move boxes through anyone else.

Plain facts

We say what is approved, and where

Before you order, we tell you what is registered in your country and what is not yet. If a number on this site matters to your decision, ask us for the document behind it.

On site

We come to your market

Local congresses, launch events and clinic visits in your country, with our doctors where it matters. A partner should not have to do the first season alone.

Korea

Used and marketed in Korea first

INFUSKIN is not an export-only line. We sell it in Korea, show it at Korean dermatology congresses and train Korean doctors on it. What you distribute is a product in use at home.
