Botox vs. Dermal Filler: What's the Difference?

"Should I get Botox or filler?" is one of the most common questions we hear at Ren Aesthetics & Wellness in Ogden, UT. People often use the two terms interchangeably, but they do very different things. Understanding the difference is the first step to getting results that look like you — just more rested and refreshed.

What Botox (and other neuromodulators) does

Botox, Dysport, and Jeuveau are neuromodulators. They work by temporarily relaxing the specific muscles responsible for movement. When those muscles relax, the lines they create soften. That's why neuromodulators are ideal for dynamic lines — the wrinkles that appear when you make expressions, like frown lines between the brows, forehead lines, and crow's feet around the eyes.

What dermal filler does

Dermal fillers don't relax muscles — they add volume. Most are made from hyaluronic acid, a substance your body produces naturally. Filler restores volume that's been lost to aging, enhances features, and smooths static lines (the ones visible even when your face is at rest). Think fuller lips, lifted cheeks, a more defined jawline or chin, and softened smile lines.

The simplest way to remember it

• Botox relaxes — it softens lines caused by movement and muscle activity.
• Filler restores — it replaces lost volume and smooths lines present at rest.
• Lines that appear when you move? Usually Botox. Volume loss or lines at rest? Usually filler.

Can you use both?

Absolutely — and many clients do. Because they address different concerns, Botox and filler are often complementary. A treatment plan might use a neuromodulator to soften the upper face while filler restores volume in the cheeks or lips. Combining them thoughtfully is how skilled injectors create balanced, natural-looking results.

How long does each last?

Neuromodulators like Botox typically last about three to four months. Hyaluronic-acid fillers generally last longer — anywhere from six to eighteen months — depending on the product and the area treated. Filler also has a built-in safety net: if you're ever unhappy with a hyaluronic-acid result, it can be safely dissolved.
