Dermal Fillers

What Are the Risks of Fillers?

Fillers are generally safe and non-invasive cosmetic products. However, it may have complications and side effects. This article explains the complications associated with dermal fillers, their safety precautions, and frequently asked questions regarding the fillers.

Cosmetic procedures have gained popularity in rejuvenating the face. Most risks are rare when a professional cosmetic doctor conducts the treatment. Some complications, like edema, granulomas, and erythema, are rare. Side effects associated with the fillers are rare and subside independently after a short period. However, the side effects of complications should be reported to the cosmetic practitioner as soon as they manifest. Similarly, a proper consultation before the treatments could mitigate certain complications like allergic reactions or side effects like bruising and swelling that normally characterize the fillers.

What Are the Risks of Fillers?

After the treatment, clients experience discomfort, bruising, mild pain, redness, and swelling. These temporary side effects are normal after the injection; clients should not be worried about them. They start reducing twenty-four hours after the treatment and subside completely after two weeks. Patients should consult their cosmetic doctor for swelling which persists beyond two weeks. There are many types of filler in the market; some may contain contaminants. According to Nomoto et al. (2021), filler may cause complications like migration. The fillers may migrate to eye bags, cheeks, or other unintended regions. If the filler is not well placed, it could lead to allergic reactions, including scarring, redness, itching, infection, and bruising. Bruising is reduced by vitamin K, aloe vera, or arnica cream. According to Corduff et al. (2022), bumps and lumps occur if the inappropriate filler is used or injected in the wrong place. These may arise instantly or advance from the agglutination of the component due to the activities of muscles. Clients should look for an experienced practitioner to reduce complications or side effects. 

Rare Complications

There are several complications that some clients notice after receiving dermal fillers, although they are very rare. Clients may experience itchiness, prolonged redness, shortness of breath, vomiting and nausea, hypersensitivity, and extreme swelling of the face and lips. It is vital to seek medical attention immediately after these complications arise. According to Jones et al. (2021), most cosmetic doctors use antihistamines to reduce allergic reactions or decide to dissolve the fillers using an enzyme injection.

Dermal fillers can also cause infections; the infections are heir to unhygienic equipment. Infections could manifest through prolonged pain and discomfort, redness and itching, inflammation, and skin shedding. Seeking a professional cosmetic doctor is essential for treating infections before they worsen.

Migration of fillers is another rare complication from the fillers. The filler may migrate and settle on unwanted regions; this happens when the cosmetic doctor injects too much filler. According to Wollina et al. (2020), injecting too much filler can cause bruising, discomfort, and discoloration. The migration of fillers can also be caused by exercises and yoga done after the treatment. Clients should consult a cosmetic doctor when they observe this.

Another complication that clients may experience is necrosis or death of tissue. Necrosis becomes unavoidable when the lips tissue does not obtain enough oxygen or if the blood vessels are blocked; this is a rare side effect unless a nonprofessional cosmetic doctor conducts the treatment. The complication may occur immediately after the treatment or may be observed a day or two after the injection.

Another rare complication is loss of vision; if the filler is injected into the blood vessels, it may cause blockage. Very few clients claim this, but such a complication becomes possible when a nonprofessional cosmetic doctor conducts the treatment. 

Safety and Precaution

Dermal fillers are safe, and clients should consider these steps. When looking for a cosmetic doctor, clients should ensure they choose a licensed cosmetic doctor to inject their filler. Clients should get treatment in a clinic with resources to handle complications or side effects. Patients with allergies should ensure that they understand the ingredients of the stuffing to see if there are any that can affect them. Before the procedure, clients should tell their cosmetic doctor about all their supplements and medications; some medicines may interact with the filler’s components. Some medications thin the blood, like aspirin and Ibuprofen. Clients should not take them before and during the procedure. However, they are advised to disclose the facts to the cosmetic doctor before the treatment. Clients should know the potential side effects and risks when receiving fillers.
