do you use a oil before or after moisturizer?

depends on the the type of oil

I usually mix it with my moisturizer :) but like the above comment it depends on the products

They are usually applied after moisturizer

I do not use facial oil at all in my daily routine except some exceptional days in the winter. I rarely use oil because I have super clog pore on my nose and some part of my skin and it kind of breaks me out sometimes.

lately I haven’t been using any serums so after my essence I apply moisturizer. since it is summer I do have the a.c on full blast and it dries my skin out more than normal so I’m currently using squalane oil every night
