The Difference Between BOTOX® Cosmetic and Dermal Fillers

BOTOX® Cosmetic and Hyaluronic Acid dermal fillers are complementary treatments. One does not replace the other.

Static vs. Dynamic

BOTOX® Cosmetic is indicated for the treatment of dynamic wrinkles (expression lines). It is aimed at smoothing away lines of expression that are caused by actions such as frowning, smiling, laughing, and squinting. Contrarily, wrinkles, lines, folds or creases (not caused by repeated expression) can be corrected with injections of dermal filler.

BOTOX® Cosmetic is not effective in treating static wrinkles; wrinkles that appear when your face is at rest. Static lines are not caused by repeated expression and are best treated by injections of dermal fillers.

Cause & Symptoms

BOTOX® Cosmetic treats the cause of dynamic wrinkles as it works on the muscles that produce the appearance of expression lines.

Dermal fillers address the symptoms of static wrinkles which appear as folds, creases, and moderate-to-deep lines as they “fill in” these lines.


As a general rule, a BOTOX® Cosmetic treatment lasts between 4-5 months. After several treatments repeated at recommended intervals, the effects of the treatment tend to last longer.

Generally, the results achieved with dermal fillers last between 8-12 months. At times they last even longer.

Time, Treatment & Recovery

The BOTOX® Cosmetic treatment is quick and does not necessitate any downtime or recovery time. The duration of the treatment itself is between 10 and 20 minutes depending on the quantity of BOTOX® Cosmetic injected.

Dermal filler treatments on the other hand could require a minimal amount of recovery time. Some patients may experience slight bruising, redness, sensitivity in the area injected, or slight discomfort. These possible side effects generally last less than a week. A dermal filler treatment could last between 20 and 60 minutes, again, depending on the amount of filler the physician is injecting.
