1. Severe Edema (Swelling Beyond Normal)
The tissue of the lips is highly sensitive. Filler substances have the ability to retain water. A certain amount of swelling is normal immediately after the procedure, but extreme cases like the one in the video indicate an aggressive response from the body to the procedure.
2. Allergic Reaction
This is one of the most common causes. The body may show hypersensitivity to the filler substance or to the local anesthetic (such as lidocaine) used in the filler. This condition is called 'angioedema' and it causes the tissues to swell rapidly.
3. Incorrect Technique and Excessive Product
If more filler is injected into the lip in a single session than it can handle, the tissue cannot withstand this pressure. Additionally, if the filler is injected at the wrong depth or too close to a blood vessel, it can disrupt circulation and trigger this appearance.
4. Vascular Occlusion (Blood Vessel Blockage)
This is the most serious scenario. If the filler substance is accidentally injected into a blood vessel, the blood flow in that area stops. This can lead not only to swelling, but if not intervened, it can also lead to tissue loss (necrosis).
