It really depends on the problem to address; fillers are gels meant to fill in crease and wrinkles, restore lost volume and Botox is meant to relax muscle tensions causing wrinkles over time. Best outcomes are often achieved with a combination of both. Unlike dermal fillers, Botox injections take effect gradually: within three to five days following the injection, with full results observed around ten days later. The effects last from three to six months and fillers (HA based) between 4 and 24 months, depending on the brand and one’s reaction to the product.

Yes, you have to but only if you want to achieve optimal and lasting results. Injections are scheduled to be administered depending on the lasting effects of the product used. As an example, Allergan Botox can safely be administered every six months and Hugel should be injected every four months.

It is best to not skip the re-injection periods to ensure some stability in the results, however nothing more frequent than every three months as it could lead to some counterproductive effects. If you stop having Botox, you will simply lose the benefits of the past treatments and your skin will gradually go back to its original condition.
