Dermal fillers are instant, so you can see a visible result immediately after injection.
It also takes up to 4 weeks for the 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.
After dermal filler treatment there is initial swelling (and potential bruising) that can last up to 2 weeks post injection.
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.
