Dumb and obvious question, but I was never taught...

Hmmmmmmmm, it depends on the skin Teni. You can do both.

For minor imperfections, conceal after. Let the foundation do the work for you first and then spot conceal only where you need to. You use less product and you won't be rubbing off all your hard work.

However for clients with major acne, scarring, rosacea etc I colour-correct first and then do foundation.

Agreed!

Yep, depends I generally do the dark shadows under my eyes before foundation (they take a LOT of covering up lol, and I use a really light concealer that brightens the area up so when the foundation goes over, it still looks nice and light), and blemishes/spots after foundation, because the one I use generally covers most of them up HTH!

I do before! I do the bags under my eyes and my eyelids and then around my nose and then put on foundation. If I had a blemish though I would prob do it after so there is better coverage.

I would have thought under.
