1. 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 PA.
2. Check before/after photos. Look for unretouched, consistent-lighting photos of patients with skin and anatomy similar to yours — not stock or marketing imagery.
3. Ask about product brands. Reputable King of Prussia med spas use FDA-approved injectables (Botox, Dysport, Juvéderm, Restylane, RHA). Ask to see the product box at the time of treatment.
4. 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.
5. Read recent reviews. Prioritize reviews from the last 12 months over older ones, and pay attention to how the clinic responds to negative feedback.
