Quick Answer
What are skin boosters?
Real glow is built inside the skin — or not at all.
In Brief
Hydration, injected where it works.
Skin boosters are tiny injections of hydrating, skin-loving ingredients, placed into the layer of skin your creams can’t reach. People commonly consider them for dryness, dullness, rough texture, and early fine lines. One thing to clear up right away: they’re not fillers. Boosters make your skin itself better. They don’t add volume or change your shape.

The Line-Up
Every Booster, and What It Does
“Skin booster” covers several different materials doing several different jobs. Here is each one Onlif uses, what it is made of, and what it is actually for.
| Booster | Material | What it is for |
|---|---|---|
| Rejuran | Polynucleotide (PN) | Repair and texture |
| Rejuran i | Polynucleotide (PN) | The eye area |
| Re2O | ECM booster | Structure, not surface |
| Tissivo | hADM — human dermal matrix | Density where skin has thinned |
| Belotero Revive | Hyaluronic acid with glycerol | Deep hydration, low pain |
| Hilloga | High-concentration hyaluronic acid | Onlif’s own formulation |
| ONStem | Stem cell derived components | Regeneration and calming |
| Exosome | Exosome preparation | Damaged or depleted skin |
| MCT | Metacell technology | Face or body |
The collagen stimulators that used to sit on this list — Juvelook i, Juvelook Volume, Radiesse and Gouri — now have their own page: Collagen Biostimulators. These aren’t interchangeable. A polynucleotide booster, a collagen stimulator and a hydration booster do different things, and a plan often uses more than one in sequence. Which applies to you is decided after your skin is examined.
Rejuran
Polynucleotide (PN)
Polynucleotide derived from salmon DNA. It supports the skin’s own repair process and regulates moisture balance, which is why it suits skin that looks tired, rough or irritated rather than skin that has lost volume. Usually a short course, then maintained.
Rejuran i
Polynucleotide (PN)
The same material formulated for the thin, sensitive skin around the eyes, where standard boosters are not appropriate. Used for fine lines and the condition of under-eye skin rather than for hollowness.
Belotero Revive
Hyaluronic acid with glycerol
The first booster in Korea to include glycerol alongside hyaluronic acid. The glycerol holds water for longer, and the formulation is noted for being more comfortable to inject than most. For dryness that moisturiser does not reach.
Hilloga
High-concentration hyaluronic acid
Developed by Onlif’s medical staff and available only here. A high-concentration hyaluronic acid injection for hydration and surface glow. This is the one treatment on this page you cannot get at another clinic.
ONStem
Stem cell derived components
A regenerative booster using stem cell derived components to support cell activity, with a calming effect that suits reactive or inflamed skin. Used where the skin needs settling as well as improving.
Exosome
Exosome preparation
Exosomes are signalling vesicles, not stem cells themselves. The preparation is used to support repair in skin that has been damaged or is slow to recover. Ask what the product is and what it is derived from — this category is marketed loosely across the industry.
Re2O
ECM booster
An extracellular matrix booster, and the one Onlif reaches for most often in this family. It supplies structural material rather than hydration.
Tissivo
hADM · human dermal matrix
Donated human dermis with the cells removed, milled below 70 microns. Supplies collagen, elastin and hyaluronic acid as ready-made scaffold where skin has thinned.

MCT
Your own plasma, processed
Meta Cell Technology. Your own blood is drawn and processed in the MCT unit, where light and heat prompt the sample to release growth factors and exosomes before it is reinjected. Because the material is yours, there is no question of what is in the vial. Used on the face or the body.
Understanding It
Three Boosters, Three Different Jobs
onlif-boosters-anatomy-01 · illustration · 1000×1100 · AI OK
Here’s something most clinics won’t slow down to explain: there are actually three kinds of “booster,” and they do different jobs. Texture boosters, this page, make your skin’s surface better: hydration, glow, smoothness. Regenerative boosters help your skin age better. Collagen boosters firm it up. They look identical in a syringe. Choosing the right one for you is the whole point of a consultation.
A Fair Question
“Fillers, boosters, collagen boosters — are these all the same thing?”
No, and knowing the difference protects your money. Fillers add volume where your face has lost it. Boosters improve the skin itself. Collagen boosters rebuild firmness over months. A clinic that blurs them is selling. A doctor who separates them, and tells you which one you actually need, is planning.
How It Works
Three Jobs, Not One
A booster is a category, not a product. What is in the syringe decides the result.
01
First, what kind of problem is it
Dryness that moisturiser does not reach needs a hydration booster. Skin that has thinned and lost density needs a collagen stimulator or an ECM booster. Skin that is irritated and slow to recover needs a repair booster. These are three different materials, and treating the wrong one wastes a course.

02
Then, which material does that job
Hydration — hyaluronic acid products such as Hilloga and Belotero Revive hold water in the skin. The effect is quick and fades, so they are repeated.
Structure — the collagen stimulators on Collagen Biostimulators prompt your own collagen. These build over months and cannot be dissolved, so they are dosed conservatively.
Repair — Rejuran, ONStem and exosome preparations support the skin’s own recovery. Used where skin is irritated, damaged or slow to heal.
onlif-boosters-mod-02 · family comparison · 1200×900 · AI OK
Hydration
Hilloga, Belotero Revive. Quick, fades, repeated.
Repair
Rejuran, ONStem, exosome. For irritated or slow-healing skin.
Structure
Re2O and Tissivo supply the matrix directly. The materials that prompt your own collagen instead — PDLLA, CaHA, PDO and PCL — are on Collagen Biostimulators. Builds over months, not reversible.
03
Then, how many and how often
Which booster, or whether you need one at all, comes from looking at your skin, not from a price list. Sometimes the plan uses more than one, but only when your skin genuinely calls for it.

Regenerative Boosters
The Repair-Speed Idea
onlif-regenerative-anatomy-01 · illustration · 1000×1100 · AI OK
“You can repaint a house every season — or you can look after the crew that maintains it.”
Before wrinkles, there’s a quieter change: your skin gets slower. Slower to bounce back from a late night. Slower to heal a breakout. A little thinner, a little less resilient. Most treatments chase the visible signs one by one. The regenerative boosters in this list support the machinery underneath, so your skin keeps up better on its own.
Young skin repairs itself quickly, and that pace slows well before any obvious wrinkle announces it. Rejuran and Rejuran i carry polynucleotides aimed at those repair processes. Exosome and ONStem are used where skin is depleted or irritated and needs calming as well as support. MCT goes further and uses your own plasma. None of them is chasing glow.
A Fair Question
“Isn’t this just a skin booster with a fancier name?”
They look identical going in. The difference is what’s in the syringe and what it’s for. Hydration boosters carry water-binding material for glow and smoothness. Regenerative boosters carry ingredients aimed at your skin’s repair processes themselves. Which one your skin actually needs — or whether it’s both, in order — is a decision your doctor makes with you. A clinic that blurs the two is just selling boosters.
Candidacy
Who It May Be For
— Your skin looks tired or flat even when you feel great.
— Fine dehydration lines are showing up, and no cream seems to reach them.
— You want that lit-from-within glow. Built into your skin, not brushed on top of it.
— You’d rather start small and gentle before considering anything bigger.

Side by Side
Which Injectable Does What
| Dermal filler | Skin booster | Collagen stimulator | Anti-wrinkle injection | |
|---|---|---|---|---|
| What it changes | Shape and volume in one place | Skin quality across an area | Support, then volume, as collagen builds | Movement of a specific muscle |
| Best for | A hollow, a fold, a defined lack of volume | Dullness, dryness, texture, pores | Overall slackness rather than one hollow | Lines caused by expression |
| When you see it | Immediately | Gradually, over weeks | Volume soon, collagen over months | Three to seven days |
| How long it lasts | Typically 6–18 months | Months; repeated as a course | Often 12 months or more | Typically 3–4 months |
| Reversible? | Yes, if hyaluronic acid | Not applicable; it fades | No — which is why it is dosed conservatively | No; it wears off |
| At Onlif | Dermal Fillers | Re2O, Skin Boosters | ONVolassom, Regenerative Boosters | Botox |
Most plans use more than one of these. Which combination suits you is something your doctor decides with you, after your face has been examined.
On the Day
What Actually Happens
Four steps, and the appointment is shorter than most people expect.
01
Consultation before anything is drawn up
Your skin is examined and the concern identified — dryness, thinning, irritation, texture. That decides which material is appropriate, and whether an injectable is the right answer at all.
02
Cleansing, then numbing cream
The area is cleansed and numbing cream applied, then left to take effect. Injections into the skin are uncomfortable without it, and skipping this step is not a kindness.
03
The injection itself
Small injections place the product into the layer where it works. How many, how deep, and across which areas follows from the plan rather than from a standard pattern.
04
Pressure, then aftercare
The injection sites are compressed to stop bleeding and dressed. Small raised points and some redness are normal and settle within hours for most people.
Key Points
What to Take Away
- “Skin booster” covers several different materials that do different jobs. Onlif uses nine.
- Polynucleotide supports repair. Hyaluronic acid holds water. ECM boosters supply the matrix itself. MCT uses your own plasma.
- Hydration boosters fade over months and are repeated; regenerative boosters are planned as a series.
- Rejuran i is formulated for the eye area.
- Exosome products are not stem cell therapy, whatever the marketing says.
- Collagen stimulators — Juvelook i, Juvelook Volume, Radiesse, Gouri — are a different family and cannot be dissolved. They are on Collagen Biostimulators.
- Wrong tool if the concern is volume or laxity.
FAQ
Questions People Ask
Fillers add volume, they change contours. Boosters improve your skin itself, glow, hydration, texture. If you actually need definition, a booster won’t get you there, and we’ll say so.
That can’t be decided from a webpage. It depends what your skin shows in person. That’s exactly what the consultation is for, and it’s a decision your doctor makes with you.
Boosters build up over a planned series, with changes appearing gradually. We’ll map your timeline before you start.
Very little. Maybe tiny marks at the injection points for a day or so. We’ll walk you through it at your visit.
No. They do what skincare can’t, and your skincare does what they don’t. Sunscreen and daily care still matter. Think of them as teammates.
Same needle, different job. A hydration booster carries water-binding material and gives glow and smoothness that fades over months, so it is repeated. A regenerative booster — Rejuran, Rejuran i, Exosome, ONStem — carries ingredients aimed at your skin’s repair processes rather than at how it looks this week. The change is slower and less photogenic early on. Which one your skin needs, or whether it is both in sequence, is decided at examination. A clinic that blurs the two is just selling boosters.
Not the same. MCT stands for Meta Cell Technology: your own blood is drawn, processed in the MCT unit where light and heat prompt the sample to release growth factors and exosomes, then reinjected. The material is yours, which removes the usual question of what is in the vial. A bought exosome product is manufactured and comes in a vial. Neither is stem cell therapy, whatever the marketing around them says.
They are collagen stimulators rather than skin boosters, so they now sit on their own page: Collagen Biostimulators. The distinction matters because they work on a different timescale and, unlike a hyaluronic acid booster, they cannot be dissolved.
