neuromoudulateurs vs agents de comblement

Botox vs. fillers: difference and what’s best for you

The quest for eternal youth and perfect beauty has always fascinated mankind. These dreams are more accessible than ever thanks to injections of dermal fillers and neuromodulators. These non-surgical treatments offer rapid results, few drawbacks and the ability to preserve a natural appearance without the need for invasive surgery. But what type of injection should you choose?
In this article, discover the advantages and differences of these two treatments, so you can make an informed decision for your appearance. Note that an initial consultation with an aesthetic doctor will enable you to refine your objectives and define a treatment plan.

How does it work?

NEUROMODULATORS: Known as Botox, Dysport, or other brands, they are made from botulinum toxin, a protein that blocks the nerve signals responsible for muscle contractions. As a result, neuromodulators relax muscles and reduce the appearance of dynamic fine lines and wrinkles.

DERMAL FILLERS: These are composed of hyaluronic acid, a substance naturally present in the body. Hyaluronic acid is used to fill in areas that have lost volume over time and to smooth out static wrinkles.

What are the main areas treated?

NEUROMODULATORS: Botox is mainly used for areas of the face where muscles are responsible for wrinkles, such as:

  • Forehead lines
  • Frown lines, the area between the eyebrows
  • Eyebrows, to elevate or lift them
  • Crow’s feet, outer corners of the eyes
  • Nose bridge
  • Lips, to reduce fine lines or correct asymmetry
  • Chin, to reduce dimples or mental crease
  • Neck lines

DERMAL FILLERS: They are generally used for areas that have lost volume:

  • Lips, to plump up and redefine the lips
  • Cheeks
  • Under eyes
  • Nose, to define the shape or straighten the tip of the nose
  • Nasolabial folds or laugh lines
  • Chin and facial contours, to reshape them

How long do the effects last?

NEUROMODULATORS: The effects of botulinum toxin (Botox, Dysport…) generally last from 3 to 6 months, after which muscles begin to contract again.

DERMAL FILLERS: Filling agents vary in duration depending on the product used and the area treated, but can last from 6 to 18 months.

Do injections cause pain or side effects?

NEUROMODULATORS: Injections of Botox, Dysport and other brands are generally well tolerated and painless. You may feel a slight stinging sensation, but this quickly disappears. Potential side effects include pain at the injection sites, temporary bruising or mild headaches, although these are rare.

DERMAL FILLERS: Dermal fillers can cause some discomfort during injection, but professionals generally use local anesthetics to minimize pain. Common side effects include bruising, temporary swelling and, rarely, allergic reactions.

How much do injections cost?

NEUROMODULATORS: Botox is generally less expensive per unit than dermal fillers. However, the total cost will depend on the quantity needed to treat the targeted area.

DERMAL FILLERS: Hyaluronic acid is slightly more expensive, but lasts longer. The cost will also depend on the quantity injected.

Combining Botox and hyaluronic acid injections

Since the areas treated and the expected effects are different, it’s common to use Botox and fillers in combination to achieve optimal results.

What’s more, the hyaluronic acid in fillers is less likely to dilute when facial muscle movement is inhibited by Botox. The results of the two synergistic injectables will last longer between treatments.

Ultimately, the choice between neuromodulators and fillers depends on your needs and goals. A consultation with a qualified aesthetic physician will help you determine the treatment plan best suited to your situation.
