Ultraviolette supreme screen

Hey hey, so I’ve been using the ultraviolette supreme screen for the past year and lately I’ve noticed it’s started pilling up on me and peeling off! This is with a bare face, with makeup, with skincare - no matter what it peels off. The product isn’t out of date. Am I doing something wrong? Has anyone else been suffering this? I opened up the next tube (my backup) I have just in case that one has gone out of date and this one is doing the same. Absolutely gutted as it’s my favourite sun cream :(
