Korean Exosomes vs American Exosomes: What Actually Differs, and What to Ask Before You Pay

I'm Dr. Hyunji Kim, Director and Lead Physician at Delphic Clinic in Gangnam. I trained at Korea University Medical Center and focus on lifting, lasers and anti-aging care, which these days includes a lot of questions about exosomes.

'Korean exosomes vs American exosomes' is a question I now hear from American, Canadian and Australian patients almost weekly. Usually they've seen the same word on a US med-spa menu at a very different price and want to know whether they're buying the same thing. This guide is my answer, including the parts the comparison usually leaves out.

Korean vs American exosomes: what actually differs

Notice the last row is the same on both sides. A good result depends on the right patient, the right amount, and a careful microneedling technique. None of that is decided by which country the vial came from.

What doesn't differ, whatever the marketing says

Exosome research is promising but early, and much of it is still lab and small-study work. That's true in Seoul and in Los Angeles. I've written about the evidence and who should simply wait in a separate guide.

Label numbers like '10 billion' or '40 billion' are another trap. They're hard to verify and don't compare cleanly between brands. I explain how to read them, and what to compare instead, in my exosome price guide.

Ask what's in the vial and how it goes in. Where it was made is the last question, not the first.— Dr. Hyunji Kim, Delphic Clinic

What exosomes cost at our clinic

We use a 5th generation exosome product, ExoHealer, usually combined with microneedling (MTS) so it reaches the skin evenly. Prices are the same for Korean and foreign patients. Details are on our ExoHealer exosome treatment page.

Who exosomes suit, and who they don't

• Suits: tired, dull or sensitive skin that's slow to recover after procedures.
• Suits: an add-on to support recovery after lasers or other skin boosters.
• Doesn't suit: sagging jawlines, where lifting is the right tool.
• Doesn't suit: deep acne scars as a stand-alone fix, or active acne breakouts on the day.

If you're comparing skin boosters more broadly, my guide to microneedling with exosomes covers how the session itself runs and what to expect after.

Five questions to send any clinic, here or at home

1. 1What is the exact product name, and what category is it sold under?
2. 2How many cc will I receive, and is microneedling included?
3. 3Who performs the treatment, a doctor or another staff member?
4. 4What redness and downtime should I plan for on my trip?
5. 5Is the price the same for foreign patients?

Consultation at Delphic Clinic is free, English and Chinese interpreters are on site, and we're near Sinnonhyeon Station Exit 3. Send these five questions with a daylight photo of your skin and I'll tell you whether exosomes are worth it for you, or whether something else would serve you better.
