Does the Goowoori Skin Booster Work for My Skin?

How Goowoori, a liquid PCL skin booster, works and which skin concerns it suits.

Published 2026-10-09 Updated 2026-10-09 Reviewed by Taehyung Kim, Medical Director · Dermatology Specialist

Goowoori is a skin booster made from polycaprolactone (PCL) in liquid form, and interest in it has been growing recently. That said, being newly known is not enough of a reason on its own to choose it; whether its mode of action, collagen remodelling, fits a person's own concern should be weighed first.

A dermatologist who has been practising for 11 years has summarised Goowoori's ingredient characteristics, how it differs from existing products, and the criteria to check when having the treatment, so that they can be grasped in 3 minutes. To give the conclusion first, Goowoori's strength lies in re-weaving the collagen mesh across the whole face to lift firmness, and the result varies with how precisely the injection areas and depth are designed.

01

What kind of treatment is the Goowoori skin booster?

Key point
Unlike existing skin boosters, which are used by diluting a powder, Goowoori is a polycaprolactone (PCL)-based skin booster that comes fully prepared in a 100 percent liquid form, and it encourages an environment in which collagen is produced in the dermal layer of the skin.

Existing skin boosters were used by diluting a powder with saline, but Goowoori comes in a 100 percent liquid form, so the way it is made is different. Because it is used straight away without mixing, it spreads evenly and is absorbed smoothly without nodules.

Polycaprolactone (PCL) is an ingredient with a long history of medical use, and it is also used as a material in thread lifting, where it encourages collagen production. Through tissue recovery and the rearrangement of collagen, the process is closer to planting roots from which cells can grow.

  • Manufacturing — comes fully prepared as a 100 percent liquid with no powder dilution, so it spreads evenly
  • Absorption — used straight away with no mixing step, so it is absorbed smoothly into the skin
  • Key ingredient — polycaprolactone (PCL) encourages a collagen-producing environment in the dermis
02

How is it different from existing skin boosters such as Rejuran?

Key point
While Rejuran, which contains a PN (polynucleotide) ingredient, focuses on improving skin texture by filling in moisture and radiance, Goowoori acts in a different way: it reshapes collagen into a mesh-like structure so that the skin can build up its own supporting strength.

Rejuran uses a PN (polynucleotide) ingredient to supplement the condition of the dermis, focusing on filling in moisture and radiance to create a dewy skin texture. Goowoori focuses on collagen remodelling, approaching the skin on the principle of re-weaving and tightening collagen like a mesh to build up the skin's own supporting strength.

By filling thinned skin, it can be expected to soften nasolabial folds and loss of firmness around the mouth, but the choice of treatment divides according to whether volume or firmness is what is needed. Although it is commonly referred to as a filler or a lifting treatment, the range it can address has limits.

03

Which skin concerns is it particularly effective for?

Key point
In cases where the entire face is sagging and fine lines have spread across a wide area, an approach that re-weaves the mesh of collagen is effective, and the lifting effect starts to show gradually after 3 to 4 weeks have passed since the procedure.

If there are many fine lines and the face has sagged, a collagen-mesh treatment is suited to improving firmness, and the effect appears after 3 to 4 weeks. If the nasolabial folds are deep, a filling treatment takes priority; if sagging is severe, combining it with lifting takes priority.

  • Fine lines and general sagging — re-weaving the collagen mesh lifts firmness
  • Deeply hollowed areas — a filling treatment should be combined first
  • Expression lines and severe sagging — muscle-relaxing treatments or lifting are considered alongside it
04

How long does it take to see results, and what determines them?

Key point
Once 3 to 4 weeks have passed after the procedure, the lifting effect gradually starts to become visible. The result of the treatment depends largely on exactly where, at what depth and in what manner the product was injected, rather than on the ingredient itself.

Because every face differs in its contours, degree of hollowing and state of ageing, the first step that determines the result is choosing the areas to focus on and designing which direction the product will spread in. Only after firmness and fat distribution have been checked is it decided whether to inject at the key points.

A real effect comes only from precise injection into the target layer at the right depth, and where sagging is severe, the perceived effect can differ by up to 200% depending on whether Ulthera (ultrasound) or Oligio (radiofrequency) is combined.

05

What criteria should be used to choose a clinic for the treatment?

Key point
A clinic should be judged by whether a board-certified dermatologist personally examines the patient's face and takes charge of everything from designing the treatment to planning it, and by whether the consultation explains the advantages, disadvantages and limitations of each option in sufficient detail.

The first thing to check is whether the doctor personally assesses the patient's skin condition and proposes a treatment that fits it. The criteria to look at are whether a dermatologist makes the diagnosis in person and takes charge from the treatment design onward, and whether the advantages, disadvantages and limitations of each option are fully explained.

It is worth checking whether, during the consultation, enough time was spent with the doctor to explain the condition of the face, the expected effect and the changes that may appear after the treatment. If the decision to proceed is made after only a short consultation, it is worth confirming once more whether the treatment fits the person's concern.

How the doctor decides

Taehyung Kim, Medical Director · Dermatology Specialist

I look at the diagnosis before word of mouth

I do not recommend a treatment just because it is a new ingredient or has a reputation by word of mouth. Only after feeling the face with my own hands to check firmness, fat distribution and skin thickness do I first judge whether this treatment actually suits the person.

I plan the injection areas and depth first

I believe that where, at what depth and in what way the product is injected shapes the result more than the ingredient does. I set the target layer differently for each face, and I proceed with the injection only after accurately fixing the key points first.

I do not try to solve every concern with one treatment

I do not tell patients that a single collagen-remodelling treatment can resolve volume loss, expression lines and sagging all at once. For deeply hollowed areas or areas of severe sagging, I let patients know in advance so that they can consider other treatments alongside it.

I take enough time for consultation

I do not cut consultations short. I first explain the advantages, disadvantages and limitations of each option, and after checking the condition of the face, we discuss whether to proceed and in which direction, and decide together.

Summary

In summary

The Goowoori skin booster remodels collagen with its PCL ingredient to lift firmness, but it is not an all-purpose treatment that resolves every skin concern at once. It can be a good choice when fine lines and general sagging are the concern, but if deeply hollowed areas or severe sagging are also present, whether to combine it with other treatments should be checked first. It is better to have the face diagnosed in person before deciding.

FAQ

Frequently asked questions

QShould I choose Goowoori or Rejuran?
A

Rejuran focuses on improving skin texture by replenishing moisture and radiance with its PN ingredient, while Goowoori focuses on remodelling collagen to establish supporting strength. Both are good products, but the choice should depend on the effect a person expects.

QWhat is Goowoori made of?
A

It is a product in which an ingredient called polycaprolactone (PCL) is completed in a 100 percent liquid form, so even its manufacturing method differs from existing skin boosters that are used by diluting a powder.

QWhen does the effect start to show?
A

Once about 3 to 4 weeks have passed after the procedure, the lifting effect gradually starts to become noticeable.

QDoes it work for deep nasolabial folds?
A

Where the nasolabial folds are deeply hollowed, Goowoori alone has limits, so a treatment that fills that area should be considered alongside it.

QWhat should be checked before the procedure?
A

It should be checked whether a dermatologist makes the diagnosis in person and takes charge from the treatment design through to the plan, and whether the advantages, disadvantages and limitations of each option are fully explained.
