What is Mosaic Skin Studio?
Mosaic Skin Studio is a medical spa with locations in Oakland (4185 Piedmont Avenue) and San Francisco's Glen Park neighborhood, plus occasional pop-ups elsewhere in the Bay Area. Its main business is cosmetic treatment: Botox and Xeomin, dermal fillers, microneedling, chemical peels, laser treatment with the Aerolase Neo Elite, PRP for skin and hair restoration. Semaglutide injections appear on its service list as one offering among many, described as "Semaglutide compounded with Vitamin B12" along with check-ins, home delivery, wellness coaching and referral to local programs. The practice is co-owned by Dr. Chantal Lunderville, MD, a board certified physician, and Stephanie Hwang, NP. Other nurse practitioners on the team include Annie S., Karen, and Jordan M. A virtual consult can be booked, and the Oakland studio is open seven days a week; the San Francisco location, run in partnership with Pono Boutique, is open Tuesdays and Thursdays only. It is worth knowing this is a cosmetic and aesthetics practice first, with weight loss as one add-on service rather than its focus.
What does it cost?
No price is published for semaglutide injections, consultations, or any membership structure tied to the weight loss service. It states that treatments are HSA and FSA eligible and that "most prescriptions are potentially covered by insurance," but it does not say which prescriptions, or how that would work for a compounded medication like semaglutide. Before assuming any discount or coverage applies, ask directly what the cash price is and whether your insurance would actually apply.
What should you ask before you book?
Ask which clinician at which location actually prescribes and manages the semaglutide program, since the team listed includes an MD and four NPs but none is named specifically for weight loss. Ask whether the semaglutide is compounded (the service description says it is compounded with B12) rather than a brand-name product, and what that means for sourcing and dosing. Ask whether the monthly or per-visit cost includes the medication itself, or is a separate charge on top of an office fee. Ask what the home delivery process involves and whether it changes the price. Ask what follow-up visits cost and how often they are required, and ask what the cancellation terms are if you decide to stop treatment partway through.
In its own words: "We offer injections of Semaglutide compounded with Vitamin B12, personalized check-ins and follow ups, home medication delivery and treatments, wellness coaching, referral to local programs, and customized dosing for you to achieve your goals."
Who is it a good fit for?
This is a good fit if you are already drawn to Mosaic Skin Studio for its cosmetic and injectable services and want to ask about adding a GLP-1 program within that same relationship, and you are comfortable getting pricing, prescriber details, and medication sourcing answered by phone or consult before committing. It is probably not the first call if weight loss is your main goal and you want a clinic built specifically around metabolic or longevity care rather than skin and aesthetics.
