What is a skin booster injection, in one paragraph?
A skin booster injection is a micro-injection that deposits an active ingredient, such as a hyaluronic acid, a polynucleotide, or a collagen biostimulator, into the dermis, the living layer roughly 1.5 to 2.5mm below the surface. Creams stop at the stratum corneum on top; a booster is placed where fibroblasts, collagen, and elastin actually live, so it works on skin density, texture, and hydration from inside. At RE:BERRY Gangnam the diagnosis of which ingredient your skin needs, and the injection itself, are done by the same licensed physician.
Effects & Progress
Effects & Progress
The ingredient is matched to what your skin actually lacks, so the plan is designed around your specific concern rather than around whichever booster is trending.
Small raised bumps appear at each injection point and usually flatten within 2 to 3 days. Any faint redness fades within a day; makeup is fine again by the next morning with sun protection.
Skin often feels more supple as it holds water better and early dermal repair begins. Any pinpoint bruising clears around this point.
The main renewal phase โ hydration, texture, and surface smoothness read differently as the delivered ingredient works within the skin's repair biology. Response speed varies by individual.
Maintenance period. Results from a completed plan generally hold for several months; RE:BERRY will guide the repeat interval that suits your skin.

Effects & Progress
Skin concerns are not interchangeable โ one face is short of water, another has lost dermal density, a third has a fragile barrier. A skin booster plan begins by reading which of these your skin shows, then designing around that specific concern. The physician maps the treatment to your deficit and your zones, so the session answers the face in front of them rather than a generic template or a product picked from a trend.
Different ingredients deliver different results, and that is the point of choosing carefully. A hyaluronic formula binds water and answers dehydration; a polynucleotide supports worn, thinning skin; a collagen biostimulator addresses laxity by prompting the skin to rebuild. Because each molecule acts on a different aspect of skin quality, the effect you feel is defined by the match โ which is why the ingredient is selected for your skin rather than assumed.
Some skin needs more than one thing โ hydration and density, or texture and barrier repair. In those cases the physician composes a protocol, layering or sequencing ingredient classes so each does its part in the right order rather than fighting for the same job. The combination is planned at consultation and adjusted at the four-week reviews, so the course is built around your goals as a structured plan and not a single blunt injection.
A booster is only as good as the product and the hand behind it. Every vial at RE:BERRY is officially imported and shown to you sealed before it is drawn up, and your skin condition is noted under standardized lighting to give a fair baseline. The placement follows a plan the treating physician designed from your skin reading โ depth, spacing, and method chosen for your zones โ and the same physician runs your four-week review.

What Delivery Into the Dermis Changes โ and When You Notice It
- The ingredient reaches the layer that builds skin: a booster is placed at 1.5 to 2.5mm, where fibroblasts and collagen sit, so it can act on density and elasticity where a cream only sits on the surface
- Micro-points spread the effect evenly: 40 to 150 injection points distribute the active across the treated zone, so the stimulus is carried across the cheeks, under-eyes, or neck and never concentrated at a single spot
- The molecule is chosen for the deficit, not the trend: hyaluronic formulas answer dehydration, polynucleotides answer worn, thinning skin, and collagen biostimulators answer laxity, and the physician reads which one your face needs
- Comfort is built in: a topical numbing cream and a 30G micro-needle keep the intradermal injections manageable for most guests, and downtime is short because nothing is cut
- Genuine product, verified in front of you: every vial at RE:BERRY Gangnam is officially imported and shown sealed before it is opened, with your skin condition noted under standardized lighting
- One physician holds the case: the doctor who reads your skin also places every point and runs your four-week review, so the diagnosis and the injection are never split between people
| Timeline | What to Expect |
|---|---|
| Small raised bumps mark each injection point and any faint redness fades within a day; makeup and normal routines resume by the next morning with sun protection | |
| The tiny bumps flatten and settle, any pinpoint bruising clears, and skin often already feels more supple as it holds water better | |
| The dermis responds to the delivered ingredient, hydration and surface smoothness read differently in the mirror, and this is when the physician re-checks and plans | |
| Skin quality from a completed plan holds through this window before a maintenance session is considered, guided by how your own skin behaves |
Three Ways a Booster Gets Into the Skin โ Manual, Multi-Needle, and MTS
| Criteria | Manual Hand Injection | Multi-Needle Device | MTS / Micro-Channel Delivery |
|---|---|---|---|
| How it works | Physician places each point individually with a single 30G needle | A device head delivers several intradermal points at once at a set depth | Fine channels are opened in the skin and product is driven through them |
| Depth control | Adjusted by hand, point by point | Fixed by the head, uniform across an area | Shallower, spread over the surface layer |
| Best suited to | Delicate zones like the under-eye and jawline, uneven density | Broad even areas such as full cheeks and forehead | Diffuse texture and glow across a whole region |
| Points per pass | Precise, one at a time | Many at once, faster over a large field | Dense micro-channels, surface-weighted |
| Comfort | Depends on technique and numbing | Even, mechanical rhythm | Generally light, surface-level |
| What guides the choice | Skin that needs a tailored, zone-by-zone hand | Large uniform areas that suit an even grid | Overall radiance rather than deep density |
Why This Matters
The method is chosen for the skin, not the other way around. A hand injection lets the physician change depth at the exact millimetre thin under-eye skin needs, while a multi-needle head covers a broad even cheek faster and more uniformly. MTS works closer to the surface for diffuse glow. Many faces get more than one method in the same session because the under-eye and the cheek are simply not the same tissue.
This is also the honest answer to why a booster is not a stronger cream. A topical product has to survive the stratum corneum, the skin's waterproof outer shield, and very little of a large molecule like hyaluronic acid crosses it. An injection steps past that barrier and sets the ingredient beside the cells that use it. The difference is the delivery route, and that route is the whole reason the treatment exists.
KHIDI's 2025 international patient survey found 41.4% of respondents rank keeping the same doctor throughout as their leading criterion. At RE:BERRY Gangnam the physician who reads which ingredient and which method your skin needs is the one who places every point and reads your four-week result โ no handoff between the diagnosis and the needle.

Why Dermal Delivery Works โ The Skin Biology Underneath a Booster
The whole logic of injecting an ingredient, not applying it, rests on where the skin's machinery sits. The dermis holds the fibroblasts that manufacture collagen, elastin, and the ground substance that binds water, and it is this layer that thins with age. Measurements of human skin have shown collagen content and thickness falling steadily across the adult decades, and the mechanical stiffness of the dermis changing measurably with age in vivo. This is the structural loss a booster is placed to address at its source, in the dermis itself, where a surface product never reaches.

Histology explains why the surface alone tells you little. Aging skin shows characteristic changes deep in the dermis โ thinner architecture, fragmented fibres, and less active fibroblast behaviour โ documented in histomorphologic studies of facial skin across age groups. A cream sitting on the stratum corneum cannot reach that. Placing an ingredient intradermally puts it beside the cells whose repair activity determines density and resilience.

What the delivered ingredient does next is a repair response, and the vocabulary of that response is well mapped. Skin regeneration is orchestrated by growth factors and cytokines that fibroblasts and keratinocytes release to rebuild matrix and restore barrier function, a signalling cascade reviewed extensively in the wound-healing literature. A booster deposited in the dermis works within that same biology. Its effect builds gradually over the following weeks, on the timeline of healing, and no visible change appears the moment it is injected.

Groundwork Questions About Skin Booster Injections
What exactly is a skin booster injection?
It is a micro-injection that places an active ingredient inside the dermis, the living layer about 1.5 to 2.5mm below the surface where collagen and fibroblasts sit. The ingredient can be a hyaluronic acid, a polynucleotide, or a collagen biostimulator. Because it is delivered under the skin rather than onto it, a booster acts on density, texture, and hydration in a way a topical product cannot.
Why does a booster need a needle when I already use a strong serum?
A serum has to cross the stratum corneum, the waterproof outer shield of the skin, and large molecules like hyaluronic acid barely get through it. Most of what you apply stays near the surface. An injection steps past that barrier and sets the ingredient beside the cells that actually use it, which is the reason boosters are injected at all.
How deep does the needle actually go?
Into the upper dermis, roughly 1.5 to 2.5mm, using a fine 30G needle. That is shallow, only a millimetre or two, so most guests feel small stings once the numbing cream has been on for 20 to 30 minutes. The physician adjusts depth by zone, since under-eye skin is far thinner than the cheek.
What are the different ways a booster can be injected?
Three common methods. A manual hand injection places each point individually and lets the physician tailor depth to delicate zones. A multi-needle device delivers several points at once at a set depth, useful for broad even areas. MTS opens fine surface channels for diffuse glow. Many faces get more than one method in a single session because different areas need different handling.
How many injection points are there in one session?
Usually between 40 and 150 micro-points, spread across the treated area so the ingredient is distributed evenly across the whole field and never pooled in one place. A session runs about 15 to 90 minutes depending on how many products are layered and how large the treated field is.
Which skin booster should I choose for my first one?
That decision starts with a skin reading, not a product name. Hyaluronic formulas answer dehydration, polynucleotides suit worn or thinning skin, and collagen biostimulators address laxity. At RE:BERRY Gangnam the physician identifies what your skin is actually short of and matches the ingredient class to it before anything is opened. Individual products have their own pages with their own detail.
Does a skin booster add volume like a filler?
No. A filler is placed deeper to create structure and lift, and it changes shape. A booster is placed in the dermis to improve the quality of the skin itself โ hydration, density, and texture โ without building contour. They answer different goals, and the physician will tell you plainly if what you want is actually a filler question.
How long is the downtime after a booster injection?
Short. Tiny 1 to 2mm bumps mark each injection point and flatten over 2 to 3 days. Any redness settles within a day, and a small number of guests get pinpoint bruising that clears in a couple of days. Makeup is fine again by the next morning with SPF 50, and you avoid sauna, alcohol, and hard exercise for about 48 hours.
When will I see a difference?
Skin often feels more supple within the first week as it holds water better, but the real change is a repair response that builds over the following weeks. By the four-week review, hydration and surface smoothness usually read differently. This gradual timeline is normal โ the ingredient works with the skin's own healing biology, which takes time.
How many sessions make up a course?
A common starting plan is three sessions spaced three to four weeks apart, then maintenance every six to twelve months, though the exact plan depends on the product and your skin. The physician confirms your own schedule at the four-week checks and does not commit you to a fixed block up front.
Does it hurt, and is there anaesthetic?
A topical numbing cream is applied and left for 20 to 30 minutes before the injections begin, so the surface is quiet by the time the needle is used. Since the needle only travels a millimetre or two, most guests describe small stings. The physician also adjusts to your feedback as the session goes on.
Is the product genuine, and how do I know?
Every vial at RE:BERRY Gangnam is officially imported, and the sealed product is shown to you and confirmed before it is drawn up. Your skin condition is noted under standardized clinic lighting at the start, which also gives you and the physician a fair baseline to compare against at the four-week review.
Who performs the injection at RE:BERRY Gangnam?
Dr. Yoon-Gon Ryu, the clinic's medical director, reads your skin, chooses the ingredient and method, and places every point personally. The diagnosis and the needle are not split between different staff, and the same physician runs your four-week review.
Where is the clinic, and how do I get there?

The case for injecting an ingredient, not applying it, rests on the biology of the dermis, the layer a booster targets. Human skin studies documented collagen content and thickness declining across the adult decades (Shuster 1975) and the mechanical properties of the dermis changing measurably with age in vivo (Escoffier 1989), while histomorphologic work traced the structural and fibroblast changes of aging skin below the surface (Bhattacharyya 2004). What a delivered ingredient triggers next is a repair response coordinated by growth factors and cytokines, mapped in depth across the wound-healing literature (Werner 2003; Barrientos 2008). A booster's effect therefore builds over weeks inside the skin's own healing biology, gradually rather than the instant it is placed.

This evidence shapes how a first skin booster is approached at RE:BERRY's Gangnam aesthetic clinic: a physician skin reading to locate the deficit before any product is named, intradermal placement at the depth where fibroblasts and collagen sit, and a four-week reassessment through the window in which the repair response develops, all under the same licensed physician.
