Redness?!

I have a lot of redness mainly on my right cheek and a little on my left, I think I may just have sensitive skin but I’m not sure. I am currently using the tea tree skincare range from Superdrug and I don’t know if that could be making it worse or helping it. Does anyone know what this is or can suggest good skincare brands that would help with this? Thanks xx

This is my right cheek
