Why Do Lumps Occur after Lip Filler?

Lumps inside the lips after a filler injection can occur for various reasons. Some are harmless and should resolve by themselves, while others may need to be treated by a professional. The following are the most common reasons:

Swelling & Bruising

Mild bruising and swelling are to be expected following a filler treatment. The lips are tender, and the needle is causing slight trauma, resulting in temporary lumps. These should resolve within a week.

Lip Filler Migration

Lumps and bumps are also signs of lip filler migration. When the filler is not placed uniformly or injected too superficially, it can produce lopsided bumps. A trained practitioner can smooth these out. 

Blood Clots

A hematoma forms when a tiny blood vessel is injured during an injection. It leads to swelling and a lumpy appearance and feel. These usually take a few weeks to clear.

Salivary Gland Obstruction

If filler is injected close to a salivary gland, it will form a cyst filled with fluid within the lip. These lumps can be soft and feel like they are moving inside the lips.

Granulomas

In rare cases, the body sees the filler as foreign and reacts by producing inflammatory bumps known as granulomas. Delayed-onset nodules (DONs) also occur due to bacterial contamination or an immune reaction.

Medical Treatment for Persistent Lumps inside Lips after Filler

If over-the-counter remedies are not helping or the lumps continue, a healthcare professional can provide more sophisticated treatment, including:

Filler Dissolving Injection

If the lumps are formed due to overfilling or migration of the filler, your physician can inject hyaluronidase to break down the filler. The enzyme dissolves hyaluronic acid safely and rapidly.

Steroid Injections

Steroid injections can be employed to decrease swelling in inflammatory nodules such as granulomas.

Aspiration or Minor Surgery

If the lump is a mucocoele (a fluid-filled bump) or a stubborn lump that doesn’t go away,  your doctor might need to drain or surgically remove it to avoid further issues.

With most medical treatments, you may see the results within days.

How to Massage Lip Filler Lumps Correctly?

If your doctor has allowed you to massage your lip filler lumps, follow these tips for best results:

  • Soak a towel in warm water, wring it out and then put on your lips for 1–2 minutes before massaging. 
  • Clean your hands well before handling your lips to avoid infection. 
  • Apply gentle, steady pressure to avoid damaging fragile tissues.​
  • Gently roll and knead the lumps with your fingertips. Push the filler into the surrounding tissue.

Can you Avoid Lumps After Lip Fillers?

Yes, you can take preventive measures to avoid the formation of lumps inside lips after fillers. Here are some practical tips:

Always Consult an Expert Practitioner

An experienced practitioner knows how to inject filler evenly so that lumps do not form. They will assess your lips–shape and size—then inject accordingly to avoid complications post-treatment.

Take Proper Care After Filler

Refrain from over-touching, pressure, and exercise for 24-48 hours. Proper aftercare makes sure your lips heal perfectly and produce the desired outcomes.

Adhere to Credible Filler Brands 

Low-cost, low-grade fillers are more likely to have complications. Consult your practitioner and ask about the quality of filler they use.

Avoid Excessive Filler in One Session 

Gradually adding the volume minimises the likelihood of lump development. If it’s your first time getting the lip job, prefer less volume to avoid overfilling.

If lumps last over two weeks or have warning signs, seek professional assistance. If you’re still in doubt, schedule a consultation for Lip filler Leeds, with a reputable aesthetic practitioner.  A proper pre-treatment consultation will help you prevent any unhappy circumstances.
