How to choose
Tips for Choosing a Med Spa in Saint Peters
- Verify medical director credentials. A licensed physician (MD or DO) should oversee injectables and laser care; ask who the medical director is and confirm their license is active in MO.
- Check before/after photos. Look for unretouched, consistent-lighting photos of patients with skin and anatomy similar to yours — not stock or marketing imagery.
- Ask about product brands. Reputable Saint Peters med spas use FDA-approved injectables (Botox, Dysport, Juvéderm, Restylane, RHA). Ask to see the product box at the time of treatment.
- Confirm pricing in writing. Get per-unit (not per-area) pricing for Botox, per-syringe pricing for fillers, and a written estimate for any package deal before paying.
- Read recent reviews. Prioritize reviews from the last 12 months over older ones, and pay attention to how the clinic responds to negative feedback.
