Botox vs. Dermal Fillers: Which One Do You Actually Need?

"Should I get Botox or fillers?" is the most common question we hear at our Myrtle Beach practice, and the honest answer is: it depends entirely on what is causing the thing you want to address. Botox and fillers are not interchangeable.

They work on completely different problems through completely different mechanisms. Getting the wrong one will not hurt you, but it also will not help you.

Here is how to know which one you actually need before you book anything.

What Botox Actually Does

Botox (and its cousins Dysport, Xeomin, Daxxify, and Jeuveau) contains botulinum toxin type A, a purified protein that temporarily blocks the nerve signal to specific facial muscles. When those muscles cannot fully contract, the overlying skin stops creasing.

That is it. It does one thing: relax a muscle.

This makes Botox extraordinarily effective for dynamic wrinkles, which are lines that form when you make expressions. Forehead lines that appear when you raise your eyebrows, crow's feet that fan out when you smile, the "11" lines between your brows when you frown: all dynamic. All excellent Botox candidates.

Botox will not do anything useful for a deep, static line that is present even when your face is completely relaxed, because that line is not caused by muscle movement.

Results appear within 3 to 14 days and last approximately 3 to 4 months, longer with Daxxify.

What Dermal Fillers Actually Do

Dermal fillers do something completely different: they add volume. Most modern fillers are made from hyaluronic acid, a substance your body naturally produces that attracts and holds water. Injected into specific areas, they restore volume that has been lost through the natural aging process, lift tissue, and smooth lines that are caused by structural deficiency rather than muscle movement.

Hollowed cheeks, sunken under-eye areas, flattened lips, deepened nasolabial folds, and undefined jawlines are all filler territory. These concerns exist because tissue volume has shifted or diminished over time.

A muscle relaxer will not fix a hollow cheek. You need to physically replace what is missing.

Hyaluronic acid fillers are also reversible with an enzyme called hyaluronidase, which is a meaningful safety advantage. Results typically last 9 to 18 months depending on the product and location.

The Simple Self-Test

Here is the quickest way to figure out which you need. Relax your face completely and look in a mirror.

Now make the expression that bothers you.

• If the line or crease appears only when you make an expression, you are dealing with a dynamic wrinkle. Botox.
• If the line or shadow is present even when your face is relaxed, you are looking at lost volume or deep static wrinkling. Filler, or possibly a skin resurfacing treatment.
• If you have both, you likely need both, which brings us to the liquid facelift.

Can You Get Both at the Same Time?

Yes, and for many patients it is the right call. Combining Botox in the upper face with strategic filler in the midface and lower face is often called a liquid facelift. It addresses dynamic wrinkles above while restoring structural volume below, creating a refreshed, balanced result that neither treatment achieves alone.

This is a good option if you are starting to notice your face looks tired even when you are not, your upper face looks tight but your cheeks are flat, or your overall appearance has shifted in a way that feels like "all of the above."

What About the Neck, Chin, and Under-Eye Area?

Loose, banded skin on the neck responds well to Botox injected into the platysmal bands, a technique called a Nefertiti lift. It creates a subtle tightening of the lower face and neck contour without surgery.

Under-eye hollowness and tear troughs respond well to carefully placed hyaluronic acid filler. Both require an injector who knows the anatomy of these areas well.

If submental fat (the double chin) is your concern, neither Botox nor traditional fillers address it. That is the territory of Kybella, which destroys fat cells directly.
