What is Rella Aesthetics?
Rella Aesthetics is a med spa with offices in Vacaville and Napa, California. Most of its work is aesthetic: Botox, dermal fillers, chemical peels, facials, Hydrafacial, IV hydration, laser treatments and microneedling. Weight loss is one more service on that list, a medical program built around compounded semaglutide, a GLP-1 medication. Dr. Zachary Wagner prescribes it. It does not list hormone therapy or peptide services.
The weight loss program starts with a virtual consultation. In its own words: "No. We can determine if you qualify medically over a brief phone consultation." Patients then give themselves one injection a week at home. Dr. Zachary Wagner holds weekly check-ins. The semaglutide is ordered through a 503A compounding pharmacy, so it is compounded, not brand-name. The clinic has a 4.9 rating on Google from 222 reviews.
This listing is for its Vacaville office at 542 Main St.
What does it cost?
It does not publish a price for the weight loss program, and it does not publish a consultation fee. Its FAQ says medication, syringes and alcohol swabs come with the subscription, but it does not publish the subscription price itself, so ask for the monthly figure before you book. It does not accept insurance, but it does accept HSA and FSA accounts.
Its Rella Memberships start at $30 a month. They are described as discounts on Botox and fillers and as complimentary treatments, not as a weight loss plan. Its FAQ says patients can cancel at any time, but finishing the full treatment, which runs 4 to 6 months, qualifies them for maintenance dosing sold as a pay per vial.
What should you ask before you book?
Ask who signs the prescription, and what medical degree and license Dr. Zachary Wagner holds. It does not print a medical degree beside his name, so ask for it directly.
Ask for the monthly subscription price, and confirm in writing that it covers the medication, syringes and swabs. Ask which pharmacy fills it and how it is tested.
Ask what the required labs cost if your primary care provider cannot send recent results. The clinic asks for hemoglobin A1C, a lipid panel and creatinine, all from within the last 6 months. Ask what follow-up visits cost and whether the weekly check-ins are included.
Ask who you call about side effects between check-ins. Ask what cancelling means in practice. Its blog says no long-term commitment is required, while its FAQ describes maintenance dosing after the full treatment. Get the terms in writing.
Who is it a good fit for?
This is a good fit if you want aesthetic treatments and a physician-guided weight loss program in one place in Vacaville or Napa, you can complete a virtual consultation and recent labs, and you are ready to pay cash for compounded semaglutide on a monthly basis. The clinic describes its program for people with a BMI over 35 who are considering surgery. It does not list hormone or peptide services, so those looking for them should look elsewhere. It is worth a call if the answers to the questions above come back in writing.
