Purging or breaking out?

Hello! I'm new to WIMJ. My oily, aging, sensitive skin has been dehydrated and breaking out in bumps, zits, irritation for a few weeks (or maybe even months?) now. I was convinced exfoliation and a good face oil might help but they did not. Internet research about irritation brought me here : )

Between this site and another one that evaluates products for comedogenic ingredients I realized pretty much every product I was using contains irritants or pore-clogging ingredients. Picked out some products using the Routine Builder on this site and so far am only using the cleanser, moisturizer and sunscreen.

It's been less than a week since I started using these products. My skintone is already much more more even and appears far more moisturized--sometimes even downright oily (which used to be typical for my skin). I realize it may take some time for the bumps and irritation to really subside but I've also been noticing some new pimples and am wondering if my skin is purging? The acne I was getting before was buried under dead, dry skin and these are definitely more oily (for lack of a better term). My skin seems healthier in all honesty but I can't tell if one of the new products is breaking me out or if my skin is just adjusting to the new routine. Any insight you could offer would be appreciated!
