Hey Nigellas, yes it was you that recommended it! 
I haven't bought it yet but intend to for use when the weather gets sunnier. It does sound like a great product.
At the moment I'm using Neutrogena oil free moisture with SPF 35 and I really like it. It's non-comedogenic (I'm pretty anal about making sure anything I put on my face is) and non greasy without being so matt it makes the skin look dull, and it works well over the Vichy product that I mentioned up thread.
Teajunky Yes Triacneal works. It contains retinaldehyde which is one metabolic step above retinol and one below pure retinoic acid (or tretinoin). So it works the same sort of way that retin-a works (ie increases cell turnover) only it's not as strong and your skin has to convert the retinaldehyde to retinoic acid once it's applied. So eventually it will produce similar (but perhaps less dramatic) results to retin-a but the process will take much longer. What it is great for though, is "retinising" the skin ie getting your skin acclimatised to using a retinoid before you go up in strength. That doesn't mean you won't experience an adjustment period with a stronger retinoid, but it will help.
As for a good cleanser for blemish prone skin, I'd just go for something really gentle. You don't want anything harsh - all the products aimed at teenagers just strip the skin and stress it out. And if you're using a retinoid, you don't want anything you use to irritate the skin further. I like Avene Extremely Gentle Cleanser. It's non-irritating, non-comedogenic (I know I go on about this but it's so important if you're prone to spots), it's very reasonably priced, and it does the job. La Roche Posay are a good brand to try too. I've heard good things about their physiological cleanser.
Sorry OP for hijacking your thread 
Another HG product for me is Dermalogica's overnight clearing gel. Full of salycylic acid, it's the best spot treatment I know. I barely ever get spots now (and if I do they're usually very superficial thanks to retin-a) but if I do I spot treat with this stuff and it kills those suckers dead.
