About Rachel Bennett

I'm Rachel. I write about Ultherapy and Ultherapy Prime in Korea, specifically in Gangnam, mostly from a 1st-person perspective. I'm Korean-American, raised in the Sunset District in San Francisco, and I've been on four Seoul trips in five years. I do not work for a clinic. I am not a doctor. What I am is the friend who actually went, took notes, came back, went again, and keeps writing about it because the U.S.-side coverage of these treatments is — to put it generously — thin.

Who I am

I'm a California-based writer in my early 30s, born and raised in San Francisco to Korean immigrant parents. I studied English and journalism at a UC, spent my 20s working in product marketing at a couple of Bay Area tech companies, and started writing about K-beauty and aesthetic medicine on the side around 2021 — right after the borders reopened and my cousin in Seoul finally let me visit. The writing turned into a habit, the habit turned into a column for a couple of U.S. lifestyle outlets, and the column turned into this archive. My beat is narrow on purpose: I write about Ultherapy and Ultherapy Prime in Korea — the device, the protocol, the cost difference versus the U.S., the recovery, and the city you recover in. That's the whole job.

Why I write about Ultherapy Prime, specifically

Honestly? Because the U.S. coverage is bad. When I started looking into MFU skin tightening before my second Seoul trip, almost everything I could find online was either a clinic blog written by a marketing intern or a Reddit thread from 2019. Nobody was writing in long form about what the device actually does, how the Korean version of the protocol differs from the U.S. version, what the realistic outcome envelope looks like across different ages, or what the recovery actually feels like on day three. So I started writing it. I'm not a clinician — I always say so up front — but I am a careful, repeat patient with four trips of personal experience and a small network of Korean-American friends who've been through the same thing. The archive is what I wish had existed when I was researching my first treatment.

How I write — first-person, plainspoken, not a doctor

I write in the first person and in plain English — the way I'd actually tell a friend over coffee. I use hedging language when I'm describing clinical outcomes ("patients report," "may help," "in my experience") because I am not in a position to tell you what your face is going to do — only what mine did, and what the published literature says, and where the two overlap. When I cite a study I link the paper or name the journal in plain text; I do not invent PubMed IDs or stage anecdotes. When I describe a clinic, I describe it categorically — by specialty, by patient experience, by language support, by location — rather than ranking it against another clinic by name. That's both a personal preference and a Korean legal requirement (의료법 제56조 4항), and I treat it as a constraint to work inside rather than around.

Conflict-of-interest disclosure

This is the part you should actually read. This site — gangnam-ultherapy-prime.com — is part of a publisher network operated by HEIM GLOBAL, a Korean medical-tourism coordinator registered with the Ministry of Health and Welfare under foreign-patient registration A-2026-04-02-06873. HEIM GLOBAL pays me to write the editorial coverage for this domain. The Hospital Hub pages on this site carry a WhatsApp coordinator channel that connects readers to HEIM GLOBAL; if a reader who comes through this site books a treatment with one of the coordinator's affiliated clinics, HEIM GLOBAL may earn a referral fee. The general editorial coverage — the treatment guides, the city pieces, the glossary, the news posts — does not carry CTAs and is not sponsored at the article level. I do not accept individual clinic briefs. I do not write under a clinic's direction. I do disclose the publisher relationship up front, here, on the disclaimer page, and in the footer of every page on the site, because that's what an honest reader deserves.

Where else to find me

I keep a low online footprint on purpose — the writing is the work and the rest is mostly noise — but a few placeholder profiles exist for editorial verification. Twitter/X: @rachelbennettsf (placeholder). Instagram: @rachel.bennett.sf (placeholder, mostly food and Han River walks). LinkedIn: linkedin.com/in/rachel-bennett-sf (placeholder, the marketing-day-job version of me). The best way to actually reach me about a piece on this site — a correction, a question, a pitch — is the editorial address on the contact page. I read it weekly. I usually answer within seven business days. If you want a coordinator introduction for an actual clinical consultation, that's the WhatsApp channel on the Hospital Hub pages, not me — I'm not a coordinator and I'd be bad at it.

Frequently asked questions

Are you actually Korean-American or is that a marketing thing?

Actually Korean-American. Both parents immigrated from Busan in the 1980s, I grew up in the Sunset District in San Francisco, and I'm fluent enough to order food and disappoint my grandmother but not fluent enough to read a Korean medical consent form without help. My cousin in Seoul translates the harder parts.

Have you actually had Ultherapy Prime, or are you writing about it from research?

I've had two Ultherapy treatments in Gangnam — both on the original device, on different trips — and one Ultherapy Prime treatment on my fourth trip. Most of the recovery and pain coverage is from my own notes; the technical and comparative coverage is from the published literature plus conversations with the Korean specialists who treated me. I always note which is which in the piece.

Do you get paid by the clinics you write about?

No. I'm paid by HEIM GLOBAL, the publisher of this site, on a flat editorial basis. I do not take individual clinic briefs and I do not write under a clinic's direction. The Hospital Hub pages do connect readers to a HEIM GLOBAL WhatsApp coordinator channel, which may earn a referral fee on bookings — and that's disclosed inline on those pages, on the disclaimer page, and on this page above.
