Glass Skin and “The Amount of Trust I Have”: Roslyn's Visit, and What Earns That Trust in My Treatment Room
Roslyn (@ohbiscuiits) captioned her glass-skin visit with one line about trust. Her doctor explains what a careful clinic should show you before a needle comes near your face.

Lying back and letting a doctor you met an hour ago work on your face, in a country where you don't speak the language, takes real trust. I'm Dr. Hyunji Kim, director of Delphic Clinic in Sinnonhyeon, Gangnam, trained at Korea University Medical Center, and I consult and treat international patients myself. Roslyn's caption is six words about trust, tagged #glassskin, and it doesn't name the treatment. So this page answers two things I'm asked about almost daily: how I approach glass skin, and what a clinic should show you before you trust it.

In her own words
the amount of trust i have
What your trust should rest on before anything starts
Trust shouldn't come from a clinic's Instagram. It should come from what happens in the room before treatment. I think it's fair for any patient, anywhere, to expect these four things.
- The doctor who examines you is the doctor who treats you — at Delphic, that's me.
- You understand what is being injected and why, with an interpreter if you need one. We have English and Chinese interpreters on site.
- The price is shown before you agree, and it's the same price a Korean patient would pay.
- You're told who the treatment does not suit, including, sometimes, you.
I wrote a longer piece on how a visitor can tell a careful clinic from a busy one, because it matters more than any single device.
Glass skin is a skin condition, not a filter
The reflective look people call glass skin comes from a smooth, well-hydrated surface. When skin is dry, rough or tired, light scatters instead of reflecting, and no serum fully fixes that. That's where skin boosters come in — tiny amounts placed in the skin to support hydration and repair.
The three boosters I choose between
- 1
Aqua glow injection
Hyaluronic acid delivered into the dermis to raise moisture levels. I choose it when the main issue is dryness. Small marks can take 3–7 days to settle.
- 2
PDRN salmon injection
PDRN and growth factors that support collagen and tissue repair. It suits tired, stressed or acne-marked skin. Skip alcohol, saunas, hot baths and hard exercise for a week afterwards.
- 3
SkinVive
A booster I use for a lit-from-within smoothness on the cheeks, 30–45 minutes, usually with same-day return. It costs more, so I keep it for patients whose skin I think will respond to it.
The parts of a booster visit nobody films
Boosters are injections, so there will be small bumps or pinpoint marks right after, and occasionally a little bruising. Most of it settles within days, but it's why I don't book boosters on your last afternoon before a flight.
The glass-skin effect also isn't instant. Hydration can look better within days, while repair-type boosters tend to show more over a few weeks. I've laid out each step's side effects, and who should wait, in a separate guide.
What glass-skin boosters cost at Delphic
Roslyn's post doesn't say what she had, so these are example first-visit menu prices for the two boosters I use most for this concern:
- Aqua Glow Injection 2.5CC (First-visit trial)₩79,000≈ $60
- Salmon Injection (First-visit trial)₩99,000≈ $70
Example first-visit menu prices for this concern, not what Roslyn paid · VAT excluded · same price for Korean and international patients · regular prices: aqua glow injection 2.5cc ₩150,000, salmon injection 3cc ₩180,000 · SkinVive 1cc first-visit ₩259,000 · your plan is set at the free consultation.
Most first visits need one booster, not two. For how the bill builds visit by visit, see my glass-skin cost breakdown.
Before you book: a short checklist
- 1
Send a photo first
Message us on WhatsApp with a bare-skin photo in daylight and your dates. I'll tell you which booster, if any, fits.
- 2
Leave a buffer
Book boosters early in your trip so small marks can settle before photos or your flight.
- 3
Ask anything
The consultation is free and 1:1. If something isn't clear, ask again — that's what it's for.
- 4
Finding us
We're a short walk from Exit 3 of Sinnonhyeon Station in Gangnam.
Is this for you?
Who this combination genuinely suits
Signs it may be time
- Your skin feels tight within hours of moisturising
- Makeup looks patchy on your cheeks by midday
- Your skin looks dull even when it's clear
- You've seen glass-skin results and want to know if your skin is a good candidate
A good fit if
- Your skin looks dry, rough or tired rather than spotty
- Skincare alone isn't giving you the smooth, reflective look you want
- You can leave a few days in your trip for small injection marks to settle
- You want a doctor to choose the booster for your skin instead of following a trend
Not the right first step if: you have active inflamed acne or a skin infection, are pregnant, bruise very easily, or fly home the same evening — in those cases I'd wait or suggest a gentler first step.
“Send me a daylight photo of your bare skin before you travel. I'll tell you honestly whether a booster will move you closer to glass skin, or whether basic care should come first.”
Questions patients ask me about this
What is the glass skin treatment in Korea?
There is no single glass-skin treatment. Most clinics use skin boosters such as hydrating or PDRN injections to improve hydration and surface smoothness, sometimes alongside gentle care. The right one depends on whether your skin is mainly dry, tired or marked.
How much do skin boosters cost in Seoul?
At Delphic Clinic, first-visit prices are ₩79,000 for a 2.5cc aqua glow injection, ₩99,000 for a salmon (PDRN) injection and ₩259,000 for SkinVive 1cc, VAT excluded. Korean and international patients pay the same.
How do I know I can trust a Korean skin clinic?
Look for a clinic where the examining doctor is the one who treats you, prices are shown before you agree, and you can understand the plan in your language. A clinic that tells you who a treatment doesn't suit is usually a good sign.
Is there downtime after a glass skin booster?
Small bumps or pinpoint marks are common right after, and some people bruise slightly. With an aqua glow injection this can take 3–7 days to settle, so it's wise to book early in your trip.
How soon will I see glass skin after a booster?
Hydration can look better within days, while repair-focused boosters tend to show more over several weeks. Results vary, and many patients plan a short series rather than one session.
