Knowing the Difference Between Botox® and Fillers

Botox® and fillers both get mentioned in conversations about facial rejuvenation, but they’re not interchangeable. Confusing them is easy when you’re new to injectables, but understanding the difference helps you figure out which one addresses your specific concern.

At Laguna Beach Aesthetics in Laguna Beach, California, Adrienne O’Connell, DO, uses both Botox and dermal fillers depending on what’s causing the lines or volume loss on your face. Here’s how to tell which one you need.

How Botox relaxes facial muscles

Botox — like its cousins Dysport®, Xeomin®, and Jeuveau® — is a neurotoxin that blocks the chemical signal between your nerves and muscles. When that signal gets interrupted, the muscle can’t contract fully. The result is less movement in the treated area, which means the skin above it stops folding into the same creases over and over.

It works on lines that show up when you make facial expressions, including:

• Forehead wrinkles when you raise your eyebrows
• Frown lines between your brows
• Crow’s feet when you smile
• Bunny lines when you scrunch your nose

Botox weakens specific muscles temporarily — typically for 3-4 months — until your body metabolizes the protein and nerve signals return. The treatment doesn’t add or remove anything from your face. It just reduces how much certain muscles move.

How dermal fillers restore volume

Dermal fillers are gels, usually made with hyaluronic acid, that are injected under your skin to add volume where tissue has thinned or sunken. Hyaluronic acid is a substance your body produces naturally to keep skin hydrated and plump, so fillers use a version of what is already present in your tissues.

Fillers treat:

• Nasolabial folds from your nose to your mouth
• Marionette lines dragging down from the corners of your mouth
• Lips that have thinned with age
• Hollow cheeks or temples
• Undereye bags and troughs
• Static lines around your mouth

The gel sits beneath the skin, propping it up from below, and alters the contour and fullness of the treated area. Most filler results last for about 6 months to 2 years.

Targeting dynamic wrinkles from muscle movement

Dynamic wrinkles occur because muscles keep pulling skin into the same fold. Every time you frown or squint, the skin creases. Do it enough times over enough years, and the crease starts to remain even when the muscle relaxes. Botox stops the muscle from yanking the skin into that position.

Static wrinkles from volume loss

Static wrinkles exist because something under the skin has changed — fat has disappeared, collagen has broken down, and bone has resorbed. The wrinkle sits there regardless of what your muscles are doing. Filler physically props the skin back up from underneath.

Which facial areas need Botox vs. filler

Upper face problems — forehead, frown lines, crow’s feet — almost always call for Botox. These are muscle-driven wrinkles. Filler won’t stop your forehead from wrinkling when you raise your eyebrows.

Lower and mid-face problems — sunken cheeks, deep folds, thin lips — usually need filler. Volume loss is the issue. Botox can’t replace fat that's disappeared or plump up a thinning lip.

When combining Botox and fillers makes sense

Plenty of people need Botox and filler because aging hits from multiple angles. Your forehead wrinkles from muscle movement, and your cheeks hollow from fat loss. Botox fixes one, filler fixes the other, and you need both to address what’s happening on your face.

Dr. O’Connell can do them in the same appointment if your treatment plan includes both.
