About Radiant Lab

What is Radiant Lab?

Radiant Lab is a medical spa at 4403 Manchester Ave STE 208 in Encinitas, California, in San Diego County. Most of what it offers is skin and body work: Sofwave skin tightening, Pure Impact muscle sculpting, XERF skin tightening, LaseMD laser hair restoration, Clarity II laser for unwanted hair, injectables, and anti-aging and acne treatments. Weight loss is one service on that list, not the center of the practice. For select clients, the clinic also offers in-home treatments.

The weight loss program builds a plan around GLP-1 medications and may add nutritional guidance and non-invasive treatments. The clinic's blog discusses semaglutide, but the program page names only GLP-1 medications, so the specific drug is worth confirming. Lia Yoon, DNP, FNP-C, RN, is the only prescriber the clinic names. In its own words: "Our approach combines medical expertise with advanced treatments." Google lists the business as a medical spa, with a rating of 5 from 132 reviews.

What does it cost?

The clinic does not publish prices, and it does not list a consultation fee. It does not say whether medication is included in any price. Payment is through Flexible Payment Plans with Cherry Financing. The clinic does not say whether it accepts insurance, and it does not publish membership or cancellation terms. Ask for the monthly cost, what the medication adds to it, and what it costs to stop, all in writing before you book.

What should you ask before you book?

Start with who signs the prescription. Ask whether Lia Yoon, DNP, FNP-C, RN, writes the GLP-1 prescription, and who manages your care after that. Then ask whether any program fee includes the medication, or whether the drug is billed separately. Find out which drug it is and whether it is brand-name or compounded. Ask what follow-up visits and lab work cost, and whether the first consultation can be done by telehealth, which the clinic does not address. If you plan to pay with an HSA or FSA card, ask whether those are accepted. Finally, ask how cancellation works and whether a membership has a term. The clinic lists no hours, so call (760) 334-5351 to confirm them.

Who is it a good fit for?

This is a good fit if you want skin, body, and weight loss care in one medical spa and you are ready to pay out of pocket, with a financing plan if you need one. It is a weaker fit if you need the prices, the medication details, and the prescriber's role confirmed in writing before you commit to anything.
