When injections do not produce the expected result
Hyaluronic acid injections are now one of the most frequently performed cosmetic procedures, particularly for the lips. When done correctly, they hydrate, reshape, and restore volume naturally.
However, sometimes the result does not meet the patient's expectations: excessive volume, asymmetry, irregularities, product migration, or an artificial appearance. In some more serious cases, particularly after injections performed by unqualified individuals ("fake injectors"), complications can arise.
In all these situations, there is an effective and safe medical solution: hyaluronidase.
What is hyaluronidase?
Hyaluronidase is an enzyme used in aesthetic medicine as antidote to hyaluronic acidIts role is to break down the injected hyaluronic acid in order to:
- ✨ Dissolving excess product
- ✨ Correction of asymmetries or over-corrections
- ✨ Treatment of certain post-injection complications
- ✨ A return to a more natural and harmonious result
Contrary to popular belief, hyaluronidase is not reserved for emergency situations. It is increasingly used in a controlled aesthetic approach, particularly for patients wishing to return to a more natural look.
In what cases is hyaluronidase used?
1. Unsightly or unnatural results
After lip or facial injections, some patients notice:
- Too large a volume
- Swollen or frozen lips
- Visible irregularities
- An asymmetry between the upper and lower lip
Hyaluronidase then allows the result to be adjusted by partially or totally degrading the injected hyaluronic acid.
2. Trend towards a return to natural products
More and more patients today wish to reduce the volume of their lips or correct an old result that no longer suits their face. Hyaluronidase offers the possibility of gradually return to the initial appearance, before any possible further, more subtle injections.
3. Injections performed using fake injectors
Some patients seek medical help several months, or even several years, after receiving injections from unqualified individuals. These injections can lead to:
- Persistent and unsightly volumes
- Marked asymmetries
- A swollen appearance that does not subside over time
In these cases, hyaluronidase is an essential tool for destroying poor quality or improperly injected hyaluronic acid.
How is a hyaluronidase injection performed?
Hyaluronidase injection is a precise medical procedure that must be performed exclusively by an experienced practitioner.
Treated areas
Depending on the problem to be corrected, hyaluronidase can be injected:
- In the red lip
- In the white part of the lip (above and below the lips)
- On the upper lip and the lower lip
Injection technique
- Injection point by point
- The use of micro-bolus along the entire length of the lip
- Very fine needles (34G), making the procedure painless or minimally painful
The goal is to break down the hyaluronic acid responsible for volume or irregularity in a homogeneous manner, while respecting the natural anatomy of the lips.
Results and follow-up
The effects of hyaluronidase are generally rapid. The volume gradually decreases and the lips regain a more natural and balanced appearance.
Depending on the case, a single session may be sufficient, but several adjustments may be necessary to obtain an optimal result.
Beware of illegal injections
⚠️ Hyaluronidase is a powerful medical productIf used incorrectly, it can lead to serious complications.
That is why :
- It should never be injected by an unqualified person
- Injections performed by unlicensed individuals pose serious and sometimes irreversible risks.
