Dermal Fillers: The Safety Conversation to Have Before You Book

Filler is a medical procedure, and the room it happens in should look like one. Most people who ask me about dermal fillers have already decided what they want. Fuller lips, softer cheeks, a smoother line from the nose to the mouth. What they have usually not decided is what they want to know before someone puts a needle near their face.

I am a registered nurse in Knoxville, Tennessee, and I spent most of my nursing career in the emergency department before transitioning to medical aesthetics. That background shapes how I talk about fillers. The result matters, but the conversation about safety comes first, and it should happen before you book, not in the chair.

Here is what I think that conversation should cover.

Start with what filler is

Most of the fillers used in the face today are made from hyaluronic acid, a sugar molecule your body already makes. At Sarah Hitchcox Aesthetics we use hyaluronic acid fillers to restore volume and add definition to areas like the cheeks and lips.

The gel is placed under the skin in small amounts. It adds volume where volume has been lost, or shape where you want more of it. It is not a neurotoxin. Botox and similar products work intramuscularly. HA filler addresses volume loss and structural deficit.

That difference matters. It tells you what a filler can and cannot do, and it explains why the safety questions are different from the ones you would ask about Botox Knox Med Spa.

Ask about anatomy, not just areas

The face is not a flat surface. Under the skin there are arteries, veins and nerves, and their paths vary from one person to the next. A good injector is not thinking about "the lips" or "the cheeks." They are thinking about where the vessels run in your face and how deep or how superficial the product should be injected based on the area of the face we are treating.

The most serious filler complication is product entering or pressing on a blood vessel. It is uncommon, but it is the reason the training and anatomy knowledge of your injector matter more than the brand of filler.

So ask directly. What is your training? What license do you hold? How do you plan the injection around the vessels in this area? An injector who welcomes those questions is telling you something. One who brushes them off is telling you something too.

Some areas call for more caution

A complication can happen in any area, so caution matters everywhere, but some areas do carry more risk than others. Lips and cheeks are the areas people ask me about most. Other areas, such as the nose, the space between the eyebrows and the skin under the eyes, sit close to important vessels, and I do not inject filler in those areas because of that risk.

A good injector should be able to explain what makes those areas different, and why they might decline to treat them at all. I would rather tell someone an area is not a good fit than take the risk.
