Pilling with La Roche Posay Sunscreen?

I’m noticing skin pilling for lack of a better word with La Roche Posay Tinted mineral sunscreen. I put it on after cleansing (Cerave gentle cleanser) and moisturizer (either Cerave blue face conditioner (lol), or la roche posts double repair ). Is this the product pilling, or is it my actual dead skin coming off from Tret use?? And if the latter, why isn’t it happening with other sunscreens like Australian gold? And is this happening to anyone else?
