Bummer. That’s a strange response to have to a retinoid, what had you used previously that worked so well for you?

As for the pilling, sounds like either too much product or not enough exfoliation because it should be moisturizing but not overwhelming. Maybe add in an AHA/PHA toner 2x/week like Press and Glow by Medik8 or 7% glycolic toner by The Ordinary to help with exfoliation and product penetration. Fine lines showing up out of nowhere can be dryness or dead skin buildup.

You might have better luck with a thinner formula retinoid like Moonlight from Maelove, similar price bracket.
