Recommended Collagen Boosters: A Comparison of Juvelook Volume, Rejuran, and Radiesse

I’m Dr. Park Tae-oh from Relieve Clinic, focusing on procedures that are as painless as possible.

"Can a collagen booster actually add volume?"

That’s a question I hear quite often in consultations.

Many people think collagen boosters are procedures that only improve skin texture, but depending on the skin condition, they can create volume much more naturally than fillers.

The fillers we commonly refer to are not all the same. Hyaluronic acid fillers, collagen-induction agents, and collagen boosters (skin boosters) are clearly different in their characteristics.

In this article, I’ll focus on collagen-based treatments used for the purpose of improving volume, especially collagen boosters.

As the weather gets colder, the skin changes noticeably. Moisture evaporates more easily, and as a result, elasticity, skin texture, and hydration all begin to break down together.

At times like this, treatments that simply fill the surface have their limits. An approach that re-stabilizes the deeper layers rather than the skin surface is needed, and the 대표적인 방법 is the collagen booster.

What is a collagen booster?

A collagen booster is a treatment that acts directly on the dermis to encourage the skin to produce collagen on its own. You can think of it as a regenerative treatment that restores dermal thickness and density while improving elasticity, skin texture, and hydration overall.

Unlike hyaluronic acid fillers, which create an immediate visible change by filling space as soon as they are injected, the biggest characteristic of a collagen booster is that the skin itself gradually improves over time.

Rather than expecting a fast collagen skin-booster effect, it is closer to restoring the skin’s basic condition.

Differences between hyaluronic acid fillers and collagen boosters

Hyaluronic acid fillers are injected into sunken areas using HA ingredients, and they maintain shape and create immediate volume based on viscosity, elasticity, and cohesiveness. Their advantages are speed and predictability.

However, because they are designed to "create volume by filling," some people may feel a foreign-body sensation or an unnatural look in certain cases.

By contrast, collagen boosters are formulated in a more liquid form, so when injected into tissue they spread quickly and are absorbed. The visible change is not immediate, but the absorbed ingredients stimulate fibroblasts in the skin and reactivate collagen production.

You can think of it as reactivating the collagen-producing ability that declines with age.

How are collagen boosters used?

Skin boosters and collagen are not procedures used only to improve skin texture. Depending on the skin condition and treatment goal, they can also be used effectively to improve volume.

When the goal is volume improvement, a special needle called a cannula is used to inject into the deep subcutaneous layer. When the goal is improving skin texture or elasticity, a thin, fine needle is used to inject multiple shallow points into the skin surface.

This is why the lineup is divided by purpose even within the same brand. A representative example is Juvelook, which is divided into Juvelook Skin and Juvelook Volume.

• Juvelook Volume

Juvelook Volume, whose key ingredient is PDLLA, has a structure that gradually breaks down in the body while stimulating fibroblasts to induce collagen production. Rather than immediately creating a large plumping effect, it focuses on creating volume by making the skin itself thicker and firmer over time.

It is suitable for areas that look sunken because the skin has become thin, or when you want to naturally restore both volume and elasticity. However, because it is a collagen-production-based treatment, proper dosage and layer design tailored to the skin condition are more important than excessive injection.

• Radiesse

Radiesse is a collagen booster based on CaHA ingredients. In the early stage, its microparticles act as a structural scaffold to create volume, and over time they continue to support collagen production. Among collagen boosters, it offers relatively distinct early volume and structure, and it is often used in areas that need support, such as the neck, jawline, and nasolabial folds.

Because it is particle-based, if the injection depth or volume is not designed precisely, a palpable sensation may remain. For this reason, the effect of Radiesse depends greatly on the injector’s experience and technique.

• Rituo

Rituo is made from acellular allograft dermis (hADM), which is created by removing only the cells from actual human dermis while leaving the collagen, elastin, GAGs, and other ECM structures intact.

It is a concept that rebuilds the "framework" of skin tissue, restoring damaged dermal structure and creating an environment where new tissue can settle in. It tends to be especially noticeable in sunken scars or areas where the skin has become very thin, and the duration of effect is also often felt to be relatively long.

Personally, I use Rituo more for improving the skin barrier and skin texture rather than for volume, and I prefer Radiesse. When I performed both treatments, I could see that Radiesse produced higher satisfaction than Rituo in terms of volume.

In the end, what matters is not the "product" but the "design"

Juvelook, Radiesse, and Rituo all share the common feature of being collagen boosters, but the choice varies depending on skin thickness, the degree of sunken areas, and the type of volume desired.

That is why I always look at the face first, assess the skin condition by area, and then choose the appropriate procedure and product instead of picking a product first. If that process is skipped, even a good product can struggle to lead to a satisfying result.

A collagen booster is not a treatment that creates rapid change; it is a tool for creating a face that improves naturally over time.

If you want slow but definite changes, first set the direction based on your own skin condition, and I hope you can experience satisfaction at Relieve through a 1:1 personalized consultation with the doctor.

Thank you. This was Dr. Park.
