Why We Don't Open Juvelook on the Day of the Procedure

Hello,

This is nbom Clinic.

"Have you ever wondered why we don't open a brand-new box of Juvelook right in front of you during the procedure?"

For Juvelook, a process called 'hydration'

—dissolving the powder-type ingredients into a saline solution—

is absolutely essential, and this process takes at least 24 hours.

If hydration is rushed on the day of the procedure, the particles may not dissolve properly, leading to the side effect of 'nodules'

(lumps forming under the skin).

For safe and natural collagen generation, meticulous pre-hydration is not an option but a mandatory process. This is exactly why it is difficult

to open the product right in front of your eyes.

1. What is Juvelook 'Hydration'?

PDLLA, the main ingredient of Juvelook, originally comes in a 'powder' form, so it cannot be injected directly into the skin.

Therefore, before the procedure, it requires a process of mixing it with a liquid, such as physiological saline, to dissolve it into an opaque white

solution. This is called Hydration.

It is not simply mixing powder into water; it is a highly delicate and core stage that requires controlling numerous variables such as time,

temperature, and concentration.

Juvelook Hydration Process

According to the basic guidelines from the Juvelook headquarters, it is recommended to inject physiological saline and leave it at room

temperature for at least 24 hours to ensure the product is completely dissolved.

If water is hastily mixed and injected on the day of the procedure, there is a very high probability that the powder will not be 100% dissolved.

If undissolved powder particles enter the skin, they cannot spread evenly and may clump together, causing side effects.

Based on personal experience and medical evaluations, 'nodules'—hard lumps felt under the skin after a Juvelook procedure—mainly

occur when the following three conditions are met.

Main Causes of Nodules	Detailed Explanation & Prevention Principles
① Improper Dilution (Insufficient Hydration)	When the powder particles are injected in an incompletely dissolved state due to a lack of time. (Prevented by ensuring a sufficient hydration period of 1 to 3 days before the procedure.)
② Shallow Injection	When the medication is injected into a superficial skin layer that is too shallow compared to the target layer.
③ Excessive & Uneven Injection	When an excessively high concentration is injected into one area, or the medication goes in in clumps. (Must avoid high concentrations and inject evenly.)

There are no absolute figures for the exact volume of saline or temperature for Juvelook hydration.

Each clinic has differences in temperature (room temperature vs. refrigerated) and dilution volume, and these details significantly impact the

results of the procedure.

Experienced Clinics: Due to a high volume of cases, they consistently perform hydration and always keep a safe, perfectly dissolved
reserve stock. Before the procedure, they thoroughly check to ensure no powder or suspended matter remains.

Inexperienced Clinics: When an unscheduled procedure is booked, there is a higher chance of rushing the hydration process, which can
directly lead to incomplete dilution (increasing the risk of nodules).

Juvelook is not a filler that instantly adds volume; rather, it improves the environment within the dermis to help your skin gradually

produce its own collagen. (True effects usually appear after about a month.)

Because the results appear gradually, the preparation process (hydration) must also not be rushed and should be given sufficient time.

While nodules can be treated after they occur, the best treatment is 'prevention' through perfect hydration so they don't happen in the first

place.

If you want safe and satisfactory results, please make sure to check the clinic's hydration principles on the day of your procedure.
