Many people expect their lips to look plump and full immediately after lip filler injections, but they are worried about whether the filler will have any negative effects. In fact, it can be very dangerous if an excessive amount is injected or if the doctor’s skills are poor. Let’s explore this lip filler injection method in more detail with HBIO Clinic.
Does lip filler injection have any negative effects?
To answer the question of whether lip filler injections have any negative effects, cosmetic dermatologists affirm that this method is completely safe and does not negatively impact health, provided it is performed by a qualified doctor and uses genuine fillers.

Consequences of Lip Filler Abuse
The answer to whether lip filler injections have any effects and what the consequences are can be extremely dangerous if you choose a low-quality facility. Abusing the dosage or using the wrong needle technique will lead to serious consequences:
- Clumping and asymmetry: Uneven distribution of filler or using a product too thick for the thin lip mucosa can cause the lips to become lumpy, uneven, and distorted when smiling.

- Vascular occlusion and tissue necrosis: This is the most serious medical complication when filler is injected directly into a blood vessel, compressing the blood circulation system and leading to necrosis of the lip area if not treated with emergency dissolving injections.
- Infection and purulent inflammation: Using non-sterile instruments creates conditions for bacteria to enter, causing prolonged swelling, pus-filled ulcers, and permanent scarring on your lips.
Criteria for distinguishing between physiological swelling and post-injection complications
In reality, after the procedure, your lips will certainly have a mild physical reaction. You need to understand the following ways to distinguish between them in order to handle them promptly:
Normal physiological swelling
The lips may be slightly swollen, slightly tight, or slightly bruised at the needle site for the first 3 to 5 days due to the water-retention reaction of HA. This phenomenon will gradually subside, and the lips will become soft and take on their normal shape after 1 to 2 weeks.

Complications of a botched lip augmentation procedure
Even after 7 days, the lips remain swollen, tender, and persistently painful. Hard lumps can be clearly felt when the mouth is closed or when the lips are touched. The skin of the lips has turned an unusually pale white or purplish-blue color.

Proper post-operative care helps the lips stabilize quickly.
Home care and lifestyle habits account for up to 40% of the success of lip shaping, helping you completely eliminate unwanted risks:
- Absolutely do not apply colored lipstick, lip balm, or any other cosmetics to your lips for the first 24 hours.
- Avoid touching your lips, do not press your lips together forcefully, do not use straws, and refrain from forceful actions such as kissing during the first week to allow the filler to set.
- Brushing your teeth should be done very gently, avoiding harsh scrubbing of the newly injected lip mucosa.
- Increase your daily water intake to help the HA (hyaluronic acid) retain moisture and maximize the lip shaping effect.
- Absolutely avoid alcohol, beer, stimulants, and foods that easily cause scarring and swelling, such as beef, water spinach, seafood, and sticky rice, for the first two weeks.

Frequently Asked Questions
Does lip filler injection affect my future pregnancy plans?
Injections are contraindicated during pregnancy or breastfeeding. However, if you have had injections before and the filler has stabilized, it will not affect your future pregnancy plans.
How long does the effect of a lip injection last?
The average duration is 12 to 24 months, depending on the type of filler you choose and your body’s natural elimination rate.
If I’m not satisfied with the lip shape after the injection, can it be corrected?
Yes. Doctors at HBIO Clinic can address this by injecting the enzyme Hyaluronidase to gently dissolve the old filler, returning the lips to their original state within 24-48 hours to create a new shape.
