Yes my foundation is so sheer it just sort of livens things up (if you see what I mean). And makes me feel I've actually made some sort of effort. Plus I don't really mind the occasional pimple or dark circles - I think they make my face a bit more interesting tbh.I think foundation on older skin, especially in daylight, is tricky. Even on SH - younger than me and pretty good skin - you can see the foundation sitting on the surface, collecting a bit in the lines.
I wonder if Sali takes hers too close to her eyes sometimes? It makes the under eye area look dry and crinkly.
(You have mentioned Australian Gold before - I must look into it as it does sound good).
