Understanding the difference is the first step towards choosing the right treatment.
Botox and dermal fillers are two of the most widely used treatments in aesthetic medicine. Yet they are frequently confused, sometimes even by beauty journalists who write regularly about cosmetic treatments. It's a fundamental distinction, Botox and dermal fillers are not competing treatments. They do entirely different jobs.
Although both involve injections and can help improve the appearance of facial ageing, they work in completely different ways. Botox relaxes muscles. Dermal fillers restore volume.
What Does Botox Do?
Botox is a brand name for botulinum toxin, a prescription-only medicine that temporarily reduces the activity of selected facial muscles.
Many facial lines develop because of repeated muscle movements such as frowning, smiling or raising our eyebrows. Over time, these movements can produce lines that become increasingly noticeable, even when those muscles are not active.
By relaxing the muscles responsible, Botox can soften these lines and help prevent them from becoming more deeply established.
It is most commonly used for:
Frown lines between the eyebrows
Horizontal forehead lines
Crow's feet around the eyes
Botox does not fill wrinkles or replace lost facial volume. Its primary action is on muscle activity.
See our main Botox information page for more useful information.
What Do Dermal Fillers Do?
Dermal fillers work quite differently.
Most modern dermal fillers contain hyaluronic acid, a substance that occurs naturally in our skin and other tissues.
As we age, changes in facial fat, bone and skin contribute to a loss of volume and alterations in facial contours.
Dermal fillers can be used to restore some of that lost volume, improve facial proportions and soften certain lines and folds.
Common treatment areas include:
Cheeks and midface
Lips
Nasolabial folds
Marionette lines
Fine surface lines, for example smokers lines
Dermal fillers do not relax facial muscles. They work by adding volume and providing structural support to the tissues.

Botox vs. Dermal Fillers — At a Glance:

So Which Treatment Is Better?
Neither. They address different aspects of facial ageing.
A patient concerned about frown lines may benefit from Botox, while someone noticing a loss of cheek volume may be better suited to dermal fillers.
Some patients benefit from a combination of both treatments. Others may need neither.
And importantly, not every wrinkle needs to be treated with an injection.
