02
Design indicators: MoD·CrR
MoD and CrR were measured.
MoD is the amount of crosslinker bound to the chains,
and CrR is the effective crosslinker ratio.
NMR was used for the measurement.
03
In vitro study: methods and results
Cell response was evaluated under defined conditions.
In an in vitro cell study using adipocytes and macrophages, the expression of inflammation-related genes was measured. The results are observations under the conditions of that test.

FAQ
Frequently asked questions
about Preface.
What is a Volume Booster?
A Volume Booster is a product that naturally adds the volume a face needs. A skin booster addresses skin condition, such as skin texture, hydration and radiance, and a Volume Booster supplements the areas of the face where volume is lacking.

What is the main ingredient of Preface?
The main ingredient of Preface is cross-linked hyaluronic acid. In Korea it is approved under the product class ‘biomaterial for tissue restoration’.
What should I check when comparing it with skin boosters and fillers?
Check the main ingredient and the approved intended use first, rather than the name of the product. Design indicators and test results should be reviewed together with their measurement methods and conditions.
Is Lorient Preface the same product as Lorient No.2, No.4 and No.6?
No. Lorient Preface is a Volume Booster made of cross-linked hyaluronic acid and is a separate product from Lorient No.2, No.4 and No.6. Check each product’s main ingredient and approved intended use in its own product information.
What do MoD and CrR measure?
They are indicators that describe the chemical structure of cross-linked hyaluronic acid. MoD is the amount of crosslinker bound to the chains, and CrR is the share of bound crosslinker attached to the chains at both ends; both were measured by NMR. The values are in the product information table, and the definitions, measurement method and sources are on the Science page. These values alone do not predict effectiveness or safety for an individual.
What was examined in the in vitro cell study of Preface?
In an in vitro cell study using adipocytes and macrophages, the expression of inflammation-related genes was measured under defined treatment conditions. The test methods, measured parameters and results are on the Science page. These results are observations under the conditions of that in vitro cell study.
