Clinical studies have shown that 4 weeks is the peak effect for dermal fillers. As we don’t want to disrupt the fillers from where they were injected, I advise my patients to be gentle when they cleanse their skin over the next couple of days after treatment, no facials, lasers, waxing, anything to the face for 2 weeks after injection and avoiding excessive hot temperatures such as saunas, steam rooms and hot yoga for 2 weeks after injection, along with no exercise for 24hrs. These will all help dermal fillers to “set in the face”, after injection.
Dermal fillers are instant, so you can see a visible result immediately after injection. However, there is initial swelling (and potential bruising) that can last up to 2 weeks post injection. It also takes up to 4 weeks for th filler to integrate into the tissue, as some fillers are more cohesive than others. I often advise my patients that they should drink plenty of water to stay hydrated after treatment, as hyaluronic based fillers are water-binding. The skin is the last organ that water goes to, so staying well hydrated can also have an effect of the result of the dermal filler.
