Extreme tightness in face after microdermabrasion and spot Intense Pulse Light treatment. Which procedure could be causing this?

Three weeks ago I had microdermabrasion and IPl to a surgical facial scar and some brown spots, but not the whole face. Last week (two weeks from procedure), I noticed enlarged pores and oily skin, tightness at times. Now three weeks after procedures, I have a lot of tightness in my face and pores are enlarged still, although not as much as last week. I know this is from one or both of the procedures. Is this common or could something else be going on?
