How soon can I wear makeup after a peel?

This question tends to surface when a peel is on the calendar and an event is close behind it.
The plain answer
According to my.clevelandclinic.org, you can wear makeup immediately after treatment or the next day. That is one source's answer for chemical peels in general, so the instructions your own provider gives for your peel come first.
Where makeup sits in the recovery timeline
Makeup is one small step in a longer recovery. For the wider picture, the Cleveland Clinic overview of chemical peels covers types of peels, conditions treated and what to expect. If your provider is using a specific brand, what makes VI chemical peels unique explains one such line.
The weeks after the peel
After makeup comes the stretch where you decide how to look after the skin for the weeks ahead. Two more references help you prepare for that conversation: the American Society of Plastic Surgeons page on chemical peels and a skin-treatment guide to chemical peels.
Skin that does not match your aftercare sheet
If your skin is doing something your aftercare sheet did not describe, call the provider who did the peel before you add anything on top. Covering a surprise with product only delays the answer.
