Injectable fillers, commonly used for cosmetic purposes, come with their own set of risks and potential complications like any other surgical procedure. However, it is important to note that while these procedures are generally considered safe when performed by an experienced cosmetic surgeon in Kolkata, there still remain some inherent risks associated with them.

Here are 10 potential risks and complications of injectable fillers –

Allergic Reactions:

Though rare, some individuals may experience an allergic reaction to the filler material. It is essential to inform your cosmetic surgeon about any known allergies or sensitivities before the procedure.


If you are considering an injectable, it is important for you to know that any injection carries a risk of infection. Therefore, proper sterilization and hygiene protocols should be followed during the procedure to minimize this risk. However, the signs of infection include redness, swelling, pain, or discharge at the injection site.

Bruising and Swelling:

It is also common to experience bruising and swelling after filler injections. This usually resolves within a few days but can persist for a week or more in some rare cases.

Lumps and Bumps:

Uneven distribution of the filler or movement of the injected substance can lead to the formation of lumps or bumps under the skin. Sometimes, these may require additional treatment to correct.

Necrosis (Tissue Death):

In some rare cases, the blood supply to the injected area may be compromised, leading to tissue death (necrosis). This is more likely to occur when the filler is injected into a blood vessel. Immediate medical attention is necessary if this occurs.

Migration of Filler:

Filler material can sometimes migrate from the injection site to other areas, leading to undesirable results. This is more common with certain types of fillers.


Granulomas are small, firm bumps that can develop as a reaction to the filler material. They may require additional treatments, such as steroid injections or surgical removal.

Overfilling or Underfilling:

Achieving the desired cosmetic result requires skill and precision. Overfilling or underfilling can lead to an unnatural appearance that may require correction.

Delayed Onset Reactions:

Some adverse reactions may not become apparent until weeks or months after the injection. These can include delayed swelling, redness, or other signs of inflammation.


In extremely rare cases, filler injections in certain areas, particularly around the eyes, can inadvertently block blood vessels and lead to temporary or permanent vision loss. However, this is a severe complication that requires immediate medical attention. 

Nevertheless, it is crucial to consult with a qualified and experienced cosmetic surgeon in Kolkata before undergoing any cosmetic procedure involving injectable fillers. The best plastic surgeon in Kolkata can provide a thorough assessment, discuss potential risks, and ensure that the procedure is suitable for your individual needs and medical history.
