When I worked with lasers there was a varying length of downtime between each laser. Fraxel laser on a high setting (for facial rejuvenation) had a longer recovery time than Medlite on a low setting (for removing sun spots). It can take 2 weeks to fully recover after a CO2 laser treatment.
The same can be said for a chemical peel – a Jessner’s peel had a downtime of a few days whereas a light salicylic peel had a shorter recovery period.
When to have dermal filler after a chemical peel or laser
I think the sensible way to approach dermal fillers after a chemical peel or laser is to treat you when the skin has recovered fully and not treating your before this time. This may mean waiting between 2 and 10 days depending on the laser or peel that you had.
When to have anti-wrinkle injections after a chemical peel or laser
I personally feel comfortable treating a patient with anti-wrinkle injections when the redness / inflammation has settled down following laser or chemical peel. There isn’t great science to back this up but just a personal preference.
