Hi mipmop, I'm a similar age, I love the Vitamin C cleanser which I use daily and really liked the the anti-ageing serum with Durian in it (can't remember what it's called, sorry). The day cream in the Vitamin C range is also great, but have only ever used sample sizes so can't report back massively miraculous de-wrinkling/brightening effects, I'm afraid....
I am happy to shell out for the cleanser, and would buy the moisturiser if money were no object and I didn't have a pile of unfinished creams/samples to use up first, but actually have found the Boots Perfect and Protect Intense serum to be as good, which is significantly cheaper.
