I THINK it may be heavy product on top of heavy product. So I looked it up. Vanicream contains heavy product like petrolatum and forms a barrier on the skin meant to help lock in moisture. Spf ALSO forms a barrier. And then Haus is silicone right? Also heavy. Basically your products are slipping and sliding over one another with nothing to grip on (just speculation)
Oh and if it helps, I use hyaluronic acid for hydration in my skin prep. I do a toner with hyaluronic acid, use a bit of azelaic acid, then use a thin layer of pond’s moisturizing cream. Then I do the same thing after washing my face at night, but I swap the azelaic acid for night retinol and then slather my moisturizer on thick.
