Skin Booster Before and After in Cheongdam, Gangnam, Seoul

Three audited booster cases are published below. The rest of this page is about the harder part: a booster changes the surface of skin, and the surface is the single easiest thing in photography to fake with a lamp, a filter or a layer of foundation.

The short answer

What a skin booster pair can honestly show you

A booster works on skin quality: the grain of the surface, how light comes back off it, how deeply fine lines sit in thin skin. So a fair comparison is a close, flat-lit frame of the same patch of skin. Anything shot at a flattering angle in warm light is showing you photography.

That is a narrower claim than the galleries you have probably been scrolling. Boosters are injected into or just under the skin as a field of small deposits, and the material then sits in a layer measured in fractions of a millimetre. A layer that thin cannot reshape a face. When a booster gallery shows a changed jaw outline or a lifted cheek, something other than the booster produced it.

The materials themselves are set out on the skin booster category page, and what each one is quoted at is on the booster price page. This page is only about how to look at the photographs.

A booster baseline is an instrument capture under fixed light, which is the only way a later frame can mean anything at this scale.
What Shows

Four things a booster comparison can legitimately be judged on

Each of these is a surface property, and each one survives being photographed at close range under flat light.

VISIBLE 01

The grain of the skin surface

Fine irregularity across the cheek and around the mouth reads at close range as texture. It is the property boosters are aimed at most directly, and it is the one a macro frame at a fixed distance records reliably.

VISIBLE 02

How light comes back off the skin

Skin that holds water scatters light differently from skin that does not. This is the real content behind the word glow, and it is also the property most easily counterfeited with a lamp, which is why the light has to be identical in both frames.

VISIBLE 03

Fine lines in thin skin

Crepe under the eye, the fine lines at the corner of the mouth, the stacked lines on a thin cheek. These are shallow and surface-bound, so a change in how deeply they sit is visible in a still frame at rest.

VISIBLE 04

The shadow cast by an open pore

What a camera records is not pore diameter but the shadow inside it, which moves with surface firmness and with the angle of the light. Read with that in mind, it is still a real observation about a treated field.

All four are local properties of one patch of skin, and all four want the same frame: close, flat-lit, at rest, with no makeup in either picture. A full-face beauty shot cannot resolve any of them, which is precisely why so many booster galleries are shot that way.

What Does Not Show

Three claims a booster photograph cannot carry, however good it looks

A changed contour. Shape belongs to volume and support, which sit far deeper than an injected skin field. Where a pair shows a lifted cheek or a sharper jaw, ask what else was done and when. A booster caption that claims shape has borrowed the credit from something in a different part of the file.
A brighter or more even tone. Pigment behaves on its own schedule, moves with sun exposure between two frames, and is trivially shifted by white balance. Nothing on this page is offered as a whitening treatment, and no pigment claim is made for any of these materials.
Tightened, lifted skin. Laxity is a mechanical finding in deeper tissue and it answers to energy platforms and threads, listed on the lifting and tightening page. A booster pair presented as a lift is answering a question it was never asked.
And a caption that names no interval. A frame taken the same week as the injection is showing settling. One taken a year later is showing a year of life. Without a stated gap, a booster pair has withheld the number that decides what it means.
Before & After

The audited booster cases Dear Clinic is able to publish

Unretouched cases treated at Dear Clinic and shown with consent. Individual results vary.

Rejuran Healer PDRN booster case at Dear Clinic, same patient photographed before and after a course of injections
Rejuran Healer · PDRN · same person, same conditions, before and after an injected course. Individual results may vary.
Second Rejuran Healer PDRN booster case at Dear Clinic showing the treated skin field before and after
Rejuran Healer · PDRN · a second case, treated field shown before and after. Individual results may vary.
Juvelook PDLLA and hyaluronic acid booster case at Dear Clinic, same patient before and after treatment
Juvelook · PDLLA with HA · same person under the same conditions, before and after. Individual results may vary.

All photos are unretouched before/after cases of the same person under the same conditions, treated at Dear Clinic and shown with consent. Individual results may vary; no specific outcome is implied or promised.

Two materials, three cases. Every booster on our list is injected here, and the archive is larger than what appears above, but a case is only published when consent and a caption that survives scrutiny travel together. Padding this page with unlabelled frames would defeat the standard the page is about.

The Nine Lines

Every booster published at Dear, and what a fair photograph of it could show

Read the middle column before the last one. A material that works on a property no camera resolves will never photograph well, whatever it does for you.

MaterialSold inWhat a comparison of it could reasonably showListed rate
Juvelook — skin and volume lines1 ccSurface grain and pore shadow across the injected field. PDLLA in an HA carrier, so any collagen-driven part is gradual and belongs in a late frame₩100,000 (≈ $70)
Juvelook Volume — specialty area1 ccThe same material at the specialty-area rate. It is not placed on the forehead or under the eye, so no pair should show it there₩200,000 (≈ $145)
Rejuran Healer2 ccFine texture and the fine lines of thin skin. PDRN, the polynucleotide purified from salmon DNA, and the most photographed booster on the list₩300,000 (≈ $215)

Sculptra1 vialPLLA, a collagen stimulator. Its change is slow and structural, so an early frame shows nothing and a fair pair is a late one₩1,000,000 (≈ $715)
Radiesse1 vialCaHA, placed neat or diluted across a plane. What a diluted plane does to surface quality is the only part a close frame can speak to₩1,200,000 (≈ $855)
Skinvive1 ccAn HA booster delivered inside the skin as a field of tiny deposits. Light behaviour is the property to look at, under identical lighting₩450,000 (≈ $320)
Belotero Revive1 ccA separate Merz product carrying the same published rate as the line above, and routinely confused with it online₩450,000 (≈ $320)
Laetigen2 ccStocked and quoted by the 2 cc unit. Whether it suits your finding is settled at diagnosis, and no published pair is offered for it here₩800,000 (≈ $570)

Rates are published in KRW with an approximate USD figure beside them, and they are the same figures whichever passport sits on the file. No course, package or session count is promised in advance on this page — what a field needs is decided at the review. The full card is on the published price list.

The Frame

How to photograph an injected skin field without flattering it

Five conditions. Break any one of them and the pair stops being evidence about a booster.

Bare skin in both frames. No makeup, no primer, no facial oil, and the same hours since cleansing. A base product changes surface reflection more than any injectable on this list.
Flat, identical light. Side light carves texture into the skin and a ring light erases it. Photograph facing the same source at the same intensity, and note where you stood.
Close and fixed. Same lens, same distance, same patch of cheek filling the same share of the frame. Texture is small, and a step back throws it away.
Every enhancement off. Beauty modes, skin smoothing and HDR are on by default on most phones and several of them do not announce it. Compare home frames against home frames only.
Write the date beside the file. Date, material, and whether anything else was done to the same field in between. A pair without those three is uninterpretable three months later, including by the person who took it.

Dear, Knowhow

How a booster outcome is measured at Dear Clinic

01 — DIAGNOSIS FIRST

Your skin-quality baseline is a measurement

EVE Muse captures in 3D under five light sources with AI analysis before the material is chosen, and the scores for texture, moisture and fine lines are kept on file. The review compares your later capture against those figures. How your skin looked in a selfie from March is not a baseline.

02 — THE FULL ARSENAL

Nine materials on one trolley, and no quota on any

Because every line on the table above is stocked here, the answer to a skin-quality complaint can be the cheapest row or none at all. Where the finding is laxity or lost volume, we do not recommend a booster course and say so at the consultation.

03 — DIRECTOR-PERFORMED

The hand that mapped the field reads the follow-up

Depth decides everything with an injected field: placed too superficially a deposit shows as a visible bump, placed too deep it does nothing for the surface. Your injection is director-performed, and the doctor who chose the depth is the one who has to account for the later frame.

Every published line is stocked, so the recommendation is not limited by what is in the fridge

The Injection Window

Why the days right after a booster produce unusable photographs

An injected field carries the marks of having been injected. Pinpoint entry points, small raised deposits that have not yet dispersed, bruising where a vessel was crossed, and general puffiness across the treated area are all ordinary and all temporary. Every one of them is also clearly visible in a close frame, which is the frame this kind of treatment has to be judged in.

So the useful frame comes after that window has closed, and the length of the window differs by material and by person. No interval is promised in advance here. Your director gives you a conservative date at the appointment and books the review for it, and the comparison is made then, against the capture rather than against a memory.

Collagen-driven materials complicate the timing further, because the part of their effect that comes from stimulation appears late by design. A pair photographed early is not evidence that the material failed; it is evidence that the photograph was taken too soon. Reported experience varies widely between individuals in the published literature, which is why no month figure appears anywhere on this page.

Caution

What belongs in a booster caption besides the result

Risks stated beside results are part of the picture. Left out, the picture has been edited before you saw it.

The ordinary reactions. Redness and pinpoint swelling on the day, bruising that can last several days, tenderness across the field, and small palpable deposits while the material disperses.
The less common ones. A visible bump or nodule where a deposit sat too superficially, a lump that persists, and infection at an entry point. Any of these is reviewed by the director who performed the injection.
Who is turned away. Active infection or inflamed skin in the field postpones an appointment. Pregnancy and breastfeeding change what is appropriate. Where the complaint is laxity, lost volume or pigment, we do not recommend a booster and the reason is given at the consultation.
What the caption should disclose. The material, the unit placed, the field treated, the interval since the last injection, and anything else done to the same area in between. Consent belongs there too, which is why a publishable archive is always smaller than the one a clinic holds.
Call, do not wait. Spreading redness, increasing pain, a hard lump that grows, or any skin colour change means contacting the clinic immediately, ahead of the booked review.

Comfort measures during an injected session are confirmed at your consultation and are set to the material and to you. Tell your director about bleeding disorders, blood-thinning medication, previous injectable treatment in the same field, autoimmune conditions, pregnancy and breastfeeding.

FAQ

Reading booster results, question by question

What actually changes in a skin booster before and after photo?
Surface properties: the grain of the skin, how light comes back off it, how deeply fine lines sit in thin skin, and the shadow inside an open pore. All four are local to the treated patch, and all four need a close, flat-lit frame at rest to be seen at all.
Why does Dear Clinic publish only three booster cases?
Because three cases in the audited archive carry both written consent and a caption that survives scrutiny. The number follows from the standard and says nothing about how much booster work is done here. More frames exist in patient files; they stay there.
Can a booster pair show a slimmer or lifted face?
No, and a pair that appears to is telling you about something else in the file. Boosters are placed in or just under the skin as a field of small deposits. Shape belongs to volume and support, which sit far deeper, so a contour change did not come from the booster in the caption.
Will a booster make my skin brighter in photographs?
Skin that holds water scatters light differently, and that is what people are seeing when they say glow. Pigment and tone are a separate matter entirely, they move with sun exposure between two frames, and no whitening claim is made for any material on this page.
How long after the injection should the second photo be taken?
After the injection marks have gone, and that window differs by material and by person. No interval is published here in advance. Your director gives a conservative date at the appointment and the review is booked for it, which is when the comparison is actually made.
How many sessions will I need before anything shows?
No session count is promised here before you are examined, and a clinic that offers one over a message has not looked at your skin. What is decided at the consultation is the material, the unit and the field. Whether anything further is worth buying is decided at the review, with the baseline capture on screen.
Why do Rejuran and Juvelook photograph differently?
They are different materials with different timing. Rejuran Healer is PDRN, the polynucleotide purified from salmon DNA, and it is aimed at fine texture in thin skin. Juvelook is PDLLA in an HA carrier, so part of its effect is collagen-driven and appears late. The two are compared directly on our Rejuran and Juvelook comparison.
Can I take my own booster before and after photos at home?
You can, if you fix the conditions: bare skin, the same flat light, the same lens at the same distance, every beauty setting switched off, and the date written beside the file. Compare home frames against home frames. A clinic capture and a phone photo are not the same measurement.
What makes a booster gallery untrustworthy?
No interval stated. Different lighting or distance between frames. Makeup in one picture and not the other. A contour or pigment claim attached to an injected skin field. Two different people offered as one comparison. Any of those, taken alone, is enough to put the pair aside.
Does bruising show up in the after photo?
It does if the photo is taken inside the injection window. Pinpoint entry marks, small raised deposits, bruising where a vessel was crossed and general puffiness are ordinary and temporary, and they are all obvious in the close frame this treatment has to be judged in. That is the main reason the frame waits.
Do the published cases mean I will get the same outcome?
No, and nothing here implies it. Each published pair is an individual case shown with consent, photographed under the same conditions in both frames. Skin quality outcomes vary with age, skin type, sun history, what else you are doing to your skin, and the material actually placed.
Can I have the assessment and an injection in one visit to Seoul?
Usually, once the capture and the consultation confirm the material suits your finding. The baseline is taken the same day, and the follow-up frame is taken at the interval your director sets, from home if you have travelled. We are open 365 days a year and answer enquiries in English as soon as possible.
