1. Who injects, and do you meet them before injection day?
It must be a licensed doctor, and ideally the same person who consulted with you. A clinic where a sales consultant talks to you and then hands you over on injection day to a doctor you have never met is a sign that the planning was not done by the person doing the work.
2. How often does the doctor do this?
Ask directly how many penile filler cases they do per month, and how many corrections from elsewhere. A doctor who does this regularly answers immediately and can describe difficult cases. A doctor who does it as a sideline to facial work usually answers vaguely. The anatomy here, and how the gel behaves, is very different from the face.
3. Which brand of filler, and do you get to see the box?
They must be able to name the brand before you book. It must be a Thai FDA-registered body filler, and the box must be opened in front of you. A clinic that calls it an imported filler without giving a name has, in effect, given no answer.
4. Is there an ultrasound in the room?
Ultrasound is used to see the skin layers and blood vessels before injection, to see existing gel if you have been injected before, and to guide the needle when dissolving. A clinic that takes this seriously has one and uses it on every case, rather than only for photos.
5. Cannula or needle?
A blunt-tipped cannula reduces bruising, lowers the chance of gel entering a blood vessel, and spreads the gel as a smooth sheet. If a clinic injects with a sharp needle in spots along the shaft, the chance of lumps and unevenness is significantly higher.
6. What is prepared in case of an emergency?
Hyaluronidase must be in the room and ready to use, not ordered when something happens. Alongside it, allergy medication, basic life-support equipment and a hospital referral plan. Ask, and watch the face of the person answering.
7. Who follows up, and how do you reach them out of hours?
You should have a direct line to the doctor or a nurse, not a page admin who replies the next morning. Problems that need to be seen quickly happen in the first hours, and often at night.
8. What does the price include, and who pays if it needs correcting?
Ask for a written quote that states the brand, the volume, what is included, and the policy when the result is uneven. A clinic that is confident in its work states clearly how it will correct it.
9. Data handling and privacy
Can you use a nickname? Is the examination room separate? How are before-and-after photos stored, who can access them, and can they be deleted on request? A clinic that asks for genital photos over chat before an appointment is a warning sign for both privacy and professional standards.
10. How the consultation feels
Does the doctor tell you the limitations and risks without being asked? Do they say who should not have it done? Do they push you to decide today? If you leave the room feeling you were sold to rather than examined, trust that feeling.
Signs to walk away immediately
- The injector is not a doctor, or will not give their name and licence number
- It is done outside a medical facility, such as a condo, hotel or beauty salon
- The price per cc is below 1,000 THB, or the brand is not disclosed
- They offer a substance they claim is permanent
- No consent form, no medical history, no examination first
- Exaggerated claims in adverts, reviews that all look alike, or pressure with a promotion that ends today
