Headaches or pain in the area of injection may be a common occurrence after fillings. Generally, this is mild and goes away quickly. Taking Tylenol or Motrin can help alleviate the headache or pain. In some cases, anti-wrinkle injections can cause a tension headache for 24 hours after the injection.
This usually happens from the frown line, as once the muscle starts to relax and you try to frown, as you normally do, it can create a little tension since you can't frown like before. Most people who have never been treated before may experience this, but after a couple of treatments, the muscle is already relaxed and prevents you from frowning, so you are less likely to frown as much after the initial treatment. Accidental injections of facial filler into blood vessels can occur anywhere on the face. However, an FDA analysis of studies and reported problems found that it was more likely to occur between the eyebrows and nose, in and around the nose, on the forehead and around the eyes. For people who are already predisposed to additional swelling in this area, rejuvenation with facial filler products may not be an ideal option for cosmetic enhancement of the lower eyelids.
Complications from improper facial filler injections under the eyes have recently become much more common, and these complications can be very noticeable and disturbing in the highly visible area of the face around the eyes. It is important to understand that the skin of the eyelid and the surrounding areas of the face are some of the most sensitive areas of the body and, unfortunately, lacrimal rejuvenation may not be ideal for each individual patient. For this reason, hyaluronidase injections remain an important therapeutic option for treating unwanted facial filler product in the lower eyelids. Most facial filler products injected into this area should ideally be placed in the tissue plane directly above the bone, or at least below the muscle layer of the eyelid. In some cases, however, due to anatomical differences in individuals, rejuvenation with facial fillers may not be suitable for everyone. As noted above, some hyaluronic acid products tend to spread more than others after being injected, and these products may not be the ideal choice for treating tear canal or lower eyelid voids. In addition, due to the delicate and complex anatomy around the eyes, not all injectors that can pick up a syringe and perform facial filler injections are qualified with the specific knowledge and advanced technical expertise necessary to perform this procedure properly and effectively.
Not all patients who have an appearance of lacrimalia or hollows of the lower eyelid are good candidates for facial filler injections in this area. It is also important to understand that revision procedures after an unsatisfactory outcome of previous facial filler injections under the eyes can sometimes be more complex than the original procedure, and there may be certain steps that need to be followed as part of a treatment plan to properly address the area of concern. Sometimes too much facial filler product may have been placed in the recesses of the lower eyelid creating an overfilling effect that can make the area look more puffy. In these cases, surgical rejuvenation of the lower eyelids is usually necessary to achieve a satisfactory cosmetic result. Often HA facial fillers can still be seen in the area under the eyes for many years after injection (in some cases up to five years later).
