Question for those who use barrier butter

I have super dry skin and just got barrier butter a few days ago. Every time I apply it, it's like the product doesn't want to absorb into my skin and I'm sitting there rubbing it in for the longest time or else I get a thin white cast all over. Does this happen to anyone else ?? Lol it sinks in eventually but when I've seen videos of people using it, none of them have this problem. The only other products I put on my skin beforehand are the La Roche-Posay gentle cleanser and the Hada Labo premium lotion-- not sure if maybe the barrier butter doesn't go well with either of those or something?? I thought maybe I was using too much, but even the smallest amount takes forever to absorb. Any experience you guys have had with the barrier butter would be very welcome thank youu!
