I've used clarins for years, since I lived in France (where prices were a bit more reasonable!).
I love their products- in winter their moisturiser really is the best one for my sensitive skin that gets very dried out.
I use multi-active day cream now, but I preferred eclat du jour before they stopped it
I like the bust gel and lotion too (again, no marks through pg here), the cleanser (don't know name sorry- it's pale green, mountain herbs or something), BFB is good, and I absolutely love the hand cream- it's one of the few that doesn't bring me out in a rash.
The assistants are lovely- I am a bit wary of beauty sales staff usually, as I am a bit scruffy looking bohemian, but they are unfailingly polite and helpful, and never pushy. In fact most recently when I was buying some, they went out of their way to give me products in the christmas packs (that cost the same as product on their own, but come with several small sized products too) meaning I got more for my money.
