In their own words
From 526+ verified Google and Yelp reviews — here’s what real patients are saying about their experience at OC Weight Loss & Med Spa.
Lindsay took her time to really understand my goals during the consultation. The staff is warm and the office feels welcoming — not at all clinical. I left with a clear plan I felt good about.
Best experience I’ve had at any medspa in Orange County. They explain everything before treatment and follow up after to make sure I’m comfortable. No pressure, just real care.
Came in for a consultation and felt zero pressure to commit. They built a plan that fit my budget and goals. Already recommending them to my friends — this team is the real deal.
The whole process was professional and personalized. Easy to book online, prompt at appointments, and a results-focused approach. Lindsay is incredible at what she does.
I tried other weight loss clinics before finding this one. The difference is the personalized medical attention — this isn’t a factory. They actually look at your labs and adjust the plan.
Clean office, friendly staff, and a provider who actually listens. They walked me through every option without trying to upsell. That kind of integrity is rare.

Your free consultation is a one-on-one visit with our medical provider to discuss your health goals, review your medical history, and design a personalized plan. There is no cost and no obligation. Book online or call (949) 416-0950.
Am I a candidate for medical weight loss?
Most adults with weight-management goals are candidates. Our provider evaluates your BMI, medical history, hormones and thyroid function, then recommends a combination of medications, injections, and lifestyle support.
Where are you located and what are your hours?
24002 Via Fabricante, Suite 201, Mission Viejo, CA 92691. Serving Orange County including Irvine, Laguna Niguel, Lake Forest, and Aliso Viejo. Open Monday through Friday 9 AM to 5 PM and Saturday 9 AM to 1 PM.
What is GLP-1 and how does Semaglutide help with weight loss?
GLP-1 (glucagon-like peptide-1) is a hormone that regulates appetite and blood sugar. Semaglutide is a GLP-1 receptor agonist medication that mimics this hormone, helping you feel full longer, reducing cravings, and slowing how quickly your stomach empties. Patients on medically supervised GLP-1 programs typically see significant, sustained weight loss when paired with nutrition guidance and lifestyle support.
How much weight can I expect to lose?
Results vary by patient, starting weight, medical history, and adherence to the plan. In clinical trials of GLP-1 medications, patients often lost 12–15% of body weight over 12 months. Your provider will set realistic expectations during your free consultation based on your goals and health profile.
How long do Botox and dermal filler results last?
Botox and other neurotoxins (Dysport, Daxxify, Xeomin) typically last 3–4 months. Hyaluronic acid dermal fillers like Juvederm and Restylane last 6–18 months depending on the product and treatment area. Sculptra (a collagen stimulator) lasts up to 2 years. We’ll recommend a maintenance schedule that fits your lifestyle and budget.
Is CoolSculpting permanent?
CoolSculpting permanently destroys treated fat cells through controlled cooling, and your body naturally eliminates them over 1–3 months. Results in treated areas are long-lasting as long as you maintain a stable weight. Most patients see 20–25% fat reduction in the treated area after one session.
Is hormone replacement therapy safe?
For appropriately screened patients, bioidentical hormone replacement therapy is considered safe and effective when monitored by a qualified medical provider. Before starting HRT, we run comprehensive lab work, review your full medical history, and discuss benefits and risks. Treatment is personalized to your specific hormone levels and adjusted based on follow-up labs.
Do you offer financing for treatments?
Yes. We accept Cherry and CareCredit for medical and aesthetic financing — both offer flexible monthly payment plans, often with 0% promotional APR. We also participate in the Alle loyalty program for Allergan products (Botox, Juvederm, etc.) which earns you points toward future treatments. Ask us about current offers at your consultation.
