What Are The Side Effects Of Hyaluronic Acid?

Hyaluronic acid is a biocompatible product that has multiple uses in the field of aesthetics. There are side effects, but a trained specialist can easily prevent them.

Lately, there has been a lot of talk about the side effects of hyaluronic acid. This is because it is one of the most appreciated skin regeneration products. This fabric gives volume to those areas where certain fabrics have become too thin. Beauty and personal care employment continues to grow.

The person using the substance must be aware of certain guidelines to avoid side effects and achieve optimal results. Read on to find some recommendations on what to avoid.

Side Effects Of Hyaluronic Acid

After applying hyaluronic acid, you need to follow a series of indications to avoid side effects. These reactions are not always a direct result of the product, but also occur when a patient does not follow professional instructions.

Redness of the area

Erythema, a side effect of hyaluronic acid, is caused by the same trauma as local injections. However, it also depends on the properties of the product used. This symptom manifests as temporary redness with mild inflammation.

It usually takes a few hours to 2 days, but you can speed up the healing process and use special creams after a session to stimulate healing that way.

Bruising due to hyaluronic acid

This is usually expected along with some inflammation and should not last more than a few days. Apply firm pressure and apply ice packs before, after or during the session to minimize both adverse effects.

If you use anticoagulants, talk to your doctor about whether you can (temporarily) stop taking them. According to a study published in The Journal of Clinical and Aesthetic Dermatology, the incidence of bruising after dermal fillers is between 19% and 24%.

asymmetry

The amount of hyaluronic acid can lead to asymmetry. That is a temporary discrepancy in the volume of the face on each side of the nose, one area being larger than the other.

Allergic reactions and hypersensitivity

These reactions are rare, as hyaluronic acid is a biocompatible product. The body assimilates it without identifying it as an external agent. This is because its components are similar to natural body substances. All allergies would manifest as local irritation.

Skin necrosis

Cutaneous necrosis, caused by compression or obstruction of a blood vessel, is a rare complication. The place most at risk of this happening is between the eyebrows. This is because this area is fed by the supratrochlear artery, which does not have a strong secondary circulation. So it cannot receive blood from any other place.

In plastic and reconstructive surgery, aspiration with a needle in a constant reciprocating motion is recommended before the filler is injected. That could prevent these kinds of complications.

Short Term Hyaluronic Acid Side Effects

Some side effects of hyaluronic acid, such as those mentioned above, appear in the short term, but not immediately. This means that they can manifest themselves a few days after the application.

Tactile or visible nodules

Lumps and bumps are common complications that result from the use of dermal fillers. They are classified as inflammatory or non-inflammatory. Late-appearing nodules lasting 4 weeks to 1 year or more are often inflammatory immune responses to hyaluronic acid.

According to the American Journal of Clinical Dermatology, inflammatory nodules are more common with permanent fillings. However, there are also reports of their development after the use of temporary fillings.

Hyaluronic acid activates the herpes simplex virus

The technician in charge must carry out prophylactic anti-herpetic treatment in surgery on the lip area of people with herpes. This is because one of the side effects of hyaluronic acid is the activation of this infection, which usually occurs in the nerves of the face.

Long Term Side Effects Of Hyaluronic Acid

Complications can occur for months or years after applying hyaluronic acid. However, these are usually misdiagnosed because of the time in between. So it is difficult to refer to it in connection with this type of treatment.

granulomas

A granulomatous reaction to a foreign substance can occur several years after these types of injections. This process is asymptomatic or accompanied by erythema and swelling.

You can treat persistent reactions to a foreign substance with intralesional corticosteroid injections. However, the American Society for Dermatologic Surgery (English link) positions hyaluronidase through studies as a viable therapy for this undesired effect.

Product migration

Hyaluronic acid migration is one of the potential complications associated with the injection of soft tissue fillers. So keep in mind that the applied substance may migrate to a site far from the injection site.

Even years later, during an evaluation of nodules, masses or swelling in the face, the filler can still be in the tissue.

The importance of going to a professional

There are many strategies to reduce the risk of complications from hyaluronic acid fillers. A good working knowledge of the side effects by a professional is essential.

Adverse reactions are rare when the correct injection technique is used. However, people should be aware that unforeseen adverse effects can occur. So be informed and follow the instructions before and after one of these sessions.
