What are the danger zones of dermal filler injections?

Fillers offer something that almost no other minimally invasive cosmetic procedure, injectable or otherwise, can: instant gratification. Both patient and provider can see the results right away, in real time—something that even the beloved Botulinum Toxin can’t provide.

Dangers of Injecting a Dermal Filler

When performed correctly, injecting a dermal filler is a safe, non-invasive medical procedure with few side effects. However, if the injector is inexperienced or unfamiliar with facial anatomy, there are serious dangers that can cause long-term harm.

The dangers of dermal filler injection include bruising, edema, skin discoloration, infection, nodular masses, paraesthesia, and vascular compromises that could lead to skin necrosis or blindness. 

Fortunately, these dangers can be avoided by observing safety measures that include keeping injections away from the biggest danger zones for dermal filler injections.

Additionally, dermal filler injections should only be performed by a medical practitioner who has received the proper training.

What are the danger zones of dermal filler injections?

Dermal fillers injection six danger zones are the glabellar area, temporal region, lip and perioral area, nasolabial fold area, nasal area and the infraorbital area.

Non-surgical techniques such as injectable treatments often have less risk, overall, than most surgical procedures.  But that does NOT mean they are entirely risk-free.

All invasive procedures carry risks and some are serious; also, patient results can vary.

If a less-trained Clinician administers dermal fillers or anti-wrinkle injections, they might even carry greater risks than a surgical procedure – because of less formal oversight of these cosmetic medicine procedures.

That’s why choosing the right Injector is SO important for your results as well as your safety, as is having a Doctor assessment of your suitability as a candidate for dermal fillers, before you get injections.

Whilst adverse effects or serious complications occur quite rarely for most non-surgical techniques, they are still a possibility.  Every invasive procedure carries risks and Cosmetic Injections and Dermal Fillers are no exception.

1. Nose

The risk of irreversible vision loss when working with the nose is high due to the proximity of the blood vessels that feed the eyes. When working with the nose, the dangerous areas are an external nasal artery and an angular artery.

Most often, cosmetologists correct the hump of the nose. In this area, it is essential to exercise caution due to the dorsal nasal artery’s proximity and the ophthalmic artery’s direct branch.

2. Glabellar Lines

The area of the glabella – the longitudinal and transverse wrinkles between the eyebrows – is one of the most dangerous zones for dermal fillers due to the location of two critical arteries here, which connect with the ophthalmic artery that feeds the retina.

With inept correction, the result can be retinal artery blockage and blindness. When treating glabellar lines, the cosmetologist faces an additional challenge due to the small diameter of the vessels and the passage of the frontal and supraorbital arteries in this area.

3. The Temples

Correction of the cheekbones and temples is dangerous due to the location of the temporal artery, its posterior parietal, and its anterior parietal branches. The temple’s superficial temporal artery is also connected to the ophthalmic nerve.

When a needle or cannula is inserted deep into the bone, an experienced cosmetologist bypasses this artery; this requires a highly qualified and experienced doctor.

4, Periorbital Zone (Under the Eyes)

This area becomes increasingly risky the closer the cannula is advanced towards the nose and the dorsal nasal artery, which is also connected to the ophthalmic artery.

The filler is usually inserted in the medial part under the eyes and not the lateral (closer to the edge of the face). This part of the periorbital zone requires the cosmetologist’s skill to bypass the infraorbital artery.

5. Cheeks

The cheeks appear to be the most protected part of the face, but it is not so simple. There are  potentially dangerous zones in the area, such as the facial, transverse arteries, the buccal branch of the maxillary artery, and the branch of the buccal artery.

Therefore, when doing contour plastic surgery of the nasolabial fold, the beautician should pay attention to the upper labial branch of the nasal artery.

6. Perioral Area

The most common area for a cosmetologist’s work requires the doctor to bypass the upper and lower labial arteries.

It is essential to understand that even innocent lip augmentation can end unexpectedly. A doctor should know where not to inject lip filler and monitor tissue discoloration and darkening (from gray to bluish shade). Worrying symptoms – ecchymosis, reticular erythema, and sharp pain at the injection site – are reasons to take immediate action.

Importance of anatomically based techniques

Facial filler injections continue to grow in popularity, however their complications can be even more impressive than their aesthetic results.

Having a thorough knowledge of the pertinent anatomy and knowing the six danger zones of the face means practitioners can tailor their injection techniques to maximise safety.

Despite detailed published descriptions of the facial vasculature, the anatomy can be quite variable, and vascular injuries can occur even after the best precautions are taken.

Likewise, actual needle depth can be difficult to track and at times unpredictable. Most importantly, practitioners need to recognise complications in a timely manner and take the appropriate measures to minimise what can be a devastating result.

Soft-tissue filler injections can revitalize the skin of the face, chest, hands, and scarred body areas. Anatomy-appropriate injection techniques, performed by certified providers with a proven track record yield the best results.
