FAQs
Do you accept insurance?
Defiant operates as a membership practice outside of insurance. This is by design. Insurance dictates 7-minute visits and reactive care. Our model allows us to spend the time you actually need, use cutting-edge therapies, and focus entirely on your outcomes — not billing codes. Many members use HSA/FSA funds, and we provide superbills for out-of-network reimbursement.
What’s included in the membership fee?
Every membership includes discounts on neurotoxins, dermal fillers, individual services, and peptides. Higher tiers unlock wellness credits for cryotherapy, vitamin shots, 3D body scans, IV drips, hyperbaric sessions, EMS muscle sculpting, lymphatic massage, and chemical peels. There are no hidden fees — your membership covers the perks, not the billing department.
Can I cancel anytime?
Yes. No contracts, no cancellation fees, no guilt trips. We keep members because we deliver results, not because we lock them in. Plus, our 90-day money-back guarantee means if you don’t feel a measurable difference, you get a full refund.
