Wrinkle-Relaxing Injections vs Dermal Fillers: What’s the Difference and Which Do You Need?
These two treatments are often mentioned together, but they do very different things. Patients frequently know they want to look less tired, smoother, or more refreshed — but are not always sure whether that points toward wrinkle-relaxing injections, dermal fillers, or sometimes both.
Understanding the distinction is one of the best ways to make treatment decisions with confidence.
At One8Clinic in Melrose Arch, Sandton, Johannesburg, facial rejuvenation is never approached as a one-size-fits-all menu. The reason is simple: wrinkles caused by muscle movement are not the same as volume loss, and they should not be treated in the same way.

What Are Wrinkle-Relaxing Injections Used For?
Wrinkle-relaxing injections are used primarily for dynamic wrinkles — lines that form because muscles repeatedly contract when you frown, smile, or raise your brows.
It softens common expression lines:
frown lines
crow’s feet
forehead lines
In practical terms, this means wrinkle-relaxing injections target movement. They work by temporarily relaxing targeted muscles, allowing the skin to appear smoother.
“Muscle-relaxing treatments can soften expression lines and help prevent deeper wrinkles from forming over time.”
— American Academy of Dermatology (AAD):
What Are Dermal Fillers Used For?
Dermal fillers treat volume loss, contour, and support. These injections plump wrinkles, restore fullness, and smooth facial lines, with immediate results that can last months or even longer depending on the type used.
In practical terms, fillers are most often used to:
restore cheek support
enhance lips
refine jawline or chin shape
soften folds and hollows
Unlike wrinkle-relaxing injections, fillers do not affect muscle movement — they enhance and support facial contours.
Why Do Patients Sometimes Need Both?

Because ageing rarely shows up in just one way.
A patient may have:
forehead or eye lines from muscle movement
cheek flattening from volume loss
deeper folds that are more structural than dynamic
This is why a combined treatment approach is often more balanced than trying to make one treatment solve every problem. Recent literature also continues to describe the distinct roles of muscle-relaxing agents and hyaluronic acid fillers in facial rejuvenation, reinforcing that they work through different mechanisms and are often complementary
Which Treatment Is Right for You?
A useful way to think about it is:
If the line appears mostly when you move → wrinkle-relaxing injections may be more relevant
If the concern is flattening, hollowness, or contour → dermal fillers may be more relevant
Of course, real faces are more complex than this simple rule, which is why consultation matters.
At One8Clinic in Sandton, the aim is not to recommend treatment based on trends, but on what your anatomy and goals actually require.
Why Choose One8Clinic in Johannesburg?

Patients often come in asking for a specific treatment when what they actually need is a proper assessment. At One8Clinic in Melrose Arch, treatment planning starts with the face in front of us, not with assumptions.
That means considering:
where movement is creating lines
where volume is missing
what will still look natural
whether a single treatment or combination approach makes more sense
This is what helps avoid over-treatment and keeps results elegant rather than obvious.

Final Thoughts
Wrinkle-relaxing injections and dermal fillers are not interchangeable. One targets expression-related wrinkles, while the other restores support, volume, and contour. The right choice depends on what is actually causing the concern you want to treat.
