Talk to me about Last Roche Posay!

[RayPurchase]

I have a sample of the 'effaclar duo' - I know it's for greasy skin (check!) but I'm not sure how to use it, it says apply once or twice day bit do I use it instead of moisturiser? Or as a cleanser? Is it effective on its own or do I need to start some sort of 'routine' with other products?
I've never had a routine beyond plain water, moisturiser and baby wipes to remove eye make up- but now my skin has suddenly turned greasy and spotty and I need to do something about it!

I cleanse, tone, Efficlar duo (am), and then moisturise. PM I might use Philosophy 'When hope is not enough' instead

Might seem a lot of faff, if you say you've never been one for a routine but MY skin is a painful wreck at the moment Recently found the Caroline Hiron's skincare blog, and have been converted

Thanks for replying, what does 'toning' do?
So you use the effalcar duo and a moisturiser? I have found my skin feel quite moisturised with it on its own. I have been washing my face with a Sebamed bar (another free sample!) then using the effaclar duo in the evening.

I'll have a look at that blog too, thanks :)
