I'm using the Balancing skin concentrate. Just been using this week. I have sensitive skin & did a patch test but no problems & have had no reactions since when using it. No miracle results & it seems quite thin & light - I use it as a serum & I seem to need to use twice as much as the Clarins one I was using, so it may be better for skin types that are not dry like mine. Will see how I feel at the end of next week - cost £11 so much cheaper than Clarins but not yet confident I would buy again.
