Hi Jen,

I don't think expensive = better, not all the time anyway!!

I've also got sensitive skin, at the moment I'm using the 'pink' range from Nutrimetics. It's working really well for me.
Previously I've used Clinique (ok but not great) and Lancome (amazing but very $$$!). Lots of supermarket brands have irritated my skin so I stay clear of them just in case, but I think Garnier have a good reputation.

Have you ever had a skin diagnosis? You can often get these for free at cosmetic counters, and sometimes even with free samples - can be helpful to find out your skin type. Good luck!
