About the studio
Dr. Lillian Park founded Lumen with one rule: never inject anything that doesn't make you look like a rested version of yourself. Eight years, three injectors, and twelve-thousand treatments later, the rule is intact.
Dr. Lillian Park trained as a dermatologist at Cedars-Sinai and spent six years inside two of LA’s largest cosmetic groups before opening Lumen in 2017. She left a partnership-track role because she could not, in good conscience, keep upselling treatments that her instinct said weren’t needed yet. The studio is the office she could not find as a patient.
Lumen opened on Sunset with three treatment suites, one injector, and a printed menu with every price visible. The menu has grown. The pricing model has not. We post every number for the same reason a good restaurant does: hiding pricing is the first sign you’re about to be talked into something.
Eight years in, Lumen has performed more than 12,000 treatments, holds a 4.9-star rating across 480 verified reviews, and is one of fewer than fifty Allergan Black Diamond practitioners in California — the highest of Allergan’s clinical tiers. We are still small on purpose: three lead injectors, five suites, never more than two clients on the floor at once.
We don’t accept insurance. We don’t charge consultation fees. We don’t sell “courses.” What you see on the menu is what you’ll see on your receipt. The consult is complimentary. Welcome.

How we work
The commitments every Lumen client gets, every visit, regardless of treatment or membership tier.
We will tell you when a treatment is not worth doing right now. Most consultations end with us recommending less, not more.
Every price is on the public menu. You will pay what you saw. No consultation fee, no facility fee, no surprise add-ons.
Lumen is intentionally small. The person treating you today is the person who knows your face next year and the year after.
Your practitioner texts you personally the next morning, day three, and day seven. Not a call center. Not a chatbot.
Every before/after on this site is a Lumen client who signed a written release. Initials only. We do not sell or license patient photos.
Closed-door consultations, no waiting room overflow, soft music. The studio is built like a salon you'd actually want to spend an afternoon in.
Our injectors
Lumen is intentionally small. The person doing your injection today will be the same person next year. You can book directly with the practitioner who knows your face, every time.

The studio experience
We designed Lumen the way our best clients told us a med spa should feel: quiet, private, slow on purpose. Natural light, soft music, champagne if you want it. Five treatment suites, never more than two clients on the floor at once.
01
Private consult rooms
Every consultation happens behind a closed door, not at an open desk. Bring a friend if you want a second opinion.
02
Same-day appointments
Most injectable appointments can be booked within 48 hours. Botox today, dinner tonight — no downtime, no waiting room.
03
Concierge text follow-up
Your injector personally texts you the next morning, day three, and day seven to check results and adjust if needed. No call centers.
04
No upsell pressure, ever
We will tell you when something is not worth doing. Most consultations end with us suggesting less, not more. The studio rule is built on it.
From our clients
I’ve been to five med spas in LA and Lumen is the only one where I’ve never felt sold to. Dr. Park talked me out of filler the first visit, said come back in six months. That earned my trust forever.
Charlotte M.
The Diamond membership pays for itself if you do Botox quarterly anyway. But what I really love is the texting after — Sofia checks in personally on day three. Concierge service in the truest sense.
Naomi A.
I came in for one thing and Maya walked me through a three-month skin plan that actually worked. Soft, natural, no one at the gala asked what I had done. They asked what skincare I was using.
