When Botox isn't enough for frown lines, can hyaluronic acid be applied afterward as a compliment, to improve results? (Photos)

The most important concept to get across is that Botox (and its competitors, Dysport & Xeomin) are used for injecting age-related hyperactivity of the muscles of facial expression, such as those responsible for the frown (scowl, angry) lines between the eyebrows. Fillers, such as Belotero Balance, on the other hand are used for elevating and smoothing fine lines, such as those present at rest between the eyebrows and that have resulted from years of daily frowning and emoting when concentrating. The point is that very often both kinds of treatments are needed to best treat this area (as well as the forehead and crow's feet regions). Botox benefits typically last three to seven months, and filler results around six to nine months. However, when both are done, the results typically synergistically last for about a year. Botox injections in the glabellar region have become quite routine over the years since I first began injecting them back in 1991. Most even novice injectors routinely perform them. However, filler injections for this region should be left to experienced injectors. Make sure to vet your doctors well and best to consult with an experienced board certified aesthetic physician. Best of luck and Happy New Year. 

As others have said, hylauronic acid fillers can be injected in this area, but make sure you seek out an experienced injector because this is a challenging and potentially dangerous area to fill. The other thing to consider is whether you still have motion of the muscles in this area after you get botox? Some patients require a higher than standard dose of botox to achieve full muscle paralysis for the glabella. Best of luck.Emile Brown, MDJohns Hopkins & Harvard Trained Plastic Surgeon

Hello,Thank you for your question and pictures. Filler can be used to help the forehead area, but please treat with someone who is experienced in filling this area as it can easily be overfilled. Consulting with a local physician in person will help you determine the best course of action for your concerns. Best of luck!

Botox often needs a little filler to fully get rid of the creases when the botox isn't enough.  You can do them on the same day if you want.

Yes, once the Botox has taken full effect and weakened the muscle sufficiently if there is still lines present at rest they can be further softened with fillers. They can be improved, but may not be fully erased. Sometimes a resurfacing treatment is also added to further improve. This is a high risk area for injection of fillers because of the blood supply, so make sure you are under the care of an experienced physician provider to minimize the risks of complications.

Some patients may simply require additional Botox if there continues to be some movement of the muscles in between the brows. If it is due to volume loss then fillers can be used but this area is associated with an increased risk in serious adverse events. I would start with PDO threads to increase collagen synthesis. Also, combining PDO threads with PRP and micro needling is an effective treatment. If these treatments were not effective then proceeding to filler injection could be an option although I would be very cautious and should only be done by those with experience in this area. Using a cannula might reduce the risk of complications. Best of luck!

If there is volume loss between the brows, or if the lines are etched in at rest, then Botox alone for the frown lines may not be enough. A little bit of filler can make a big difference, although this area is more prone to side effects, so make sure to only get injected by a highly trained cosmetic physician such as a dermatologist for optimal results (look, duration, etc), and optimal safety.

what your are explaining is not an uncommon phenomenon - over time we can get some volume loss in the brows that cause our brows to deflate in 3D - and while movement can exacerbate this, some patients will see lines even with no movement. some filler to re-inflate the fat pads beneath can help with this, and as a by-product you will also notice some brow elevation and re-shaping. 
be sure to see an experienced injector as there are many large vessels in this area.
good luck

If you really want to get rid of those wrinkles, you might want to consider treatment with fractionated lasers or microneedling. These options are a more permanent solution that fillers and are much safer for use on the forehead. These treatments are also more optimal for addressing fine lines and wrinkles than fillers.

I love placing Belatero in the elevens before I treat the glabella with Xeomin or Botox. It makes treating this area last longer with a better result.  I have been doing this for years with great results and my clients love the results.
