You should not inject filler in areas with major blood vessels, especially those connected to the eye, such as the glabella (between eyebrows), nasal bridge/tip, forehead (near supraorbital/supratrochlear arteries), and temples, due to risks like blindness from vascular occlusion (blockage). Other high-risk spots include the nasolabial folds (NLF), corners of the mouth (oral commissure), and under the eyes (infraorbital region), where arteries are dense. Deep injections on bone in these areas are particularly dangerous.
Identifying High-Risk Areas for Fillers
The areas around the eyes, particularly the tear troughs, and the temples are known for their intricate vascular networks. The nasolabial folds and perioral regions also pose risks due to their proximity to major blood vessels.
Avoid complications by understanding the danger areas and arteries to steer clear of when injecting dermal fillers
Frontal branch of the Superficial temporal artery: This prominent artery along the side of the head can be visible in some individuals. Injecting filler into this artery in the central forehead can lead to haematoma. In rare cases it may cause vascular occlusion with potential ophthalmic complications.
Avoid alcohol, if possible, during this time frame for the same reason. Avoid exercise or strenuous activity for 24 hours to decrease the risk of bruising/swelling. Avoid excessive heat, like a sauna, for 24 to 48 hours to decrease the risk of swelling as well.
Lymphatic spread — Filler can move if it gets into your lymph vessels. Massage — If you rub the area too hard after treatment, it may lead to migration. Muscle activity — The areas around the mouth, lips, and eyes move more than other areas of the face, possibly leading to migration.
Avoiding Physical Disturbance to Facial Fillers
It's particularly important to avoid pressure on the treated area for the first 48 hours after treatment. If you experience any discomfort or minor swelling, apply a cool compress to the area for 10 minutes every half an hour on the day of treatment.
Vascular complication can occur even when being careful and taking into account rules of safe injection: the use of a cannula is better than a needle in a dangerous 3D-anatomy, cannula / needle is withdrawn as the filler is injected depositing small amounts, injecting slowly ensuring to keep the cannula / needle in ...
Areas such as lips and nasolabial folds tend to be the most painful because those areas have more nerves running through them. Cheeks, tear troughs, chin and jaw line tend to be less uncomfortable. Some redness, swelling and discomfort can be expected after receiving fillers.
The riskiest areas for Botox involve locations with crucial blood vessels and delicate muscles, primarily the glabella (between eyebrows) due to arteries that can cause blindness if blocked, the forehead/brow area risking eyelid droop (ptosis) or unnatural brow shapes, and the perioral region (mouth area), where poor placement can affect speech, smiles, or cause puckering. The masseter muscle (jaw) and neck (platysmal bands) are also sensitive, potentially causing chewing difficulty or swallowing issues with improper technique, requiring expertise to avoid complications like necrosis or paralysis.
These danger zones for cheek filler include the infraorbital region under the eyes, the angular artery near the nose, and areas close to the supraorbital and supratrochlear arteries, where improper placement may lead to side effects or adverse effects.
Types of Dermal Fillers and Their Lifespan
These fillers are traditionally thought to last between 6 to 18 months, depending on the specific product and the area treated. They dissolve gradually over time as the body naturally metabolizes the hyaluronic acid.
The "Botox Rule of 3" isn't one single rule but refers to key guidelines: 3 areas (forehead, frown lines, crow's feet are common), waiting at least 3 months between treatments to prevent resistance and maintain results, and a 3-to-5 day period for results to fully appear after the 3-to-4 month duration of the treatment. Key post-injection rules include avoiding bending/lying down for 4 hours and other treatments for 14 days.
Are they safer than Botox®? There are more complications with dermal fillers than with Botox®, hence it is not safer. However, it is not that necessary to compare the two treatments, as they are usually used in different parts of the face and used to treat different problems.
Many people are sharing their journeys of moving away from fillers and embracing their natural look. They often cite reasons such as: Overfilled Look: Over time, the face can appear overly plumped and unnatural. Side Effects: Bruising, swelling, and lumps are common side effects that can be off-putting.
Dermal fillers are injected locally and stay in the tissue where they are placed. When administered properly, fillers are not absorbed into the bloodstream, so they do not transfer into breast milk (Alam, 2021).
The glabella, the area between the eyebrows, and the forehead are some of the most dangerous areas for dermal filler injections. The blood vessels in this region are interconnected and lie close to the skin's surface, increasing the risk of complications.
However, most people find that the pain from fillers is more intense than the pain from Botox injections. This is because Botox is injected into the muscle, while fillers are injected into the skin.
Understanding the True Value of Dermal Fillers
Type of Filler: Hyaluronic acid fillers average $715 per syringe, while non-hyaluronic acid fillers average $901. Treatment Area: Lips may require 1-2 syringes ($650-$1,600), while cheeks can need 2-4 syringes ($1,300-$3,200).
Intense Pain at the Injection Site: The most immediate and common symptom is severe pain. This occurs as the filler material enters the blood vessel and begins to spread. Rapid Swelling of the Lips: Significant swelling can develop within minutes on the side where the injection was made.
DON'T: Engage in Strenuous Exercise or Hot Environments.
Stay away from intense workouts, saunas, or hot tubs for at least 24-48 hours. Increased blood flow can exacerbate swelling and bruising.
With the widespread use of dermal fillers, there has been an ensuing rise in reported adverse events, including intraarterial occlusion. From 2000 to 2020, a three-fold increase of blindness or stroke secondary to filler injection was observed.
Hydration improves hyaluronic acid filler results. Drink plenty of water and use topical moisturizers containing hyaluronic acid.
First of all, can you eat after lip fillers? We recommend that any numbing agent has fully worn off before eating, to avoid accidentally biting your mouth (ouch!). We would also suggest that you avoid overly chewy or crunchy foods in the first 24 hours post-treatment.
In most cases, dermal fillers are safe and temporary. However, improper injection or unapproved filler products can cause long-term issues like scarring, tissue damage, or granulomas. Choosing qualified providers minimizes this risk.
