Who is performing the treatment, and what is their license?
Ask for the name and license type of the person holding the needle or the device, not the practice owner. In many med spas the owner is a physician who is rarely on site, and the treatment is delegated to staff. You want to know who is treating you and what they are licensed to do.
Who is the supervising physician, and are they reachable?
Many states require a physician to oversee injectable and laser treatments and to be available if something goes wrong. Ask who that physician is and how they are reached during your appointment. A clear answer signals a practice that follows the rules. A vague one is a flag.
How many times have you performed this exact treatment?
Experience with the specific procedure carries more weight than years in the field generally. A provider who does a treatment every week manages it differently from one who does it now and then.
What happens if there is a complication?
Every serious provider has a plan: how they handle an adverse reaction, who they call, and how they reach you afterward. A specific, confident answer tells you they have seen complications and know how to manage them.
Can you show me the product and confirm it is FDA approved?
Ask to see the vial or device and confirm the brand. Counterfeit and unapproved injectables are a real problem at the low end of the market. A reputable provider sources from authorized distributors and will show you without hesitation.
