Well in all fairness to Melvita, Aurora, Sodium Benzoate isn't a horrible or damaging ingredient on its own (v. natural in fact) there just is a possibility that it will react rather harmfully with Vit C thus making it carcinogenic in a reacted form but since manufacturers will never give insight into their exact formulations it's really hard as a consumer to know whether it will or not in those concentrations and/or pH levels. I do wish manufacturers would give the warning though for the possibility, even if it's slight, if they manage to warn pregnant women about retinol they can do this just as well.
Keith, is there any particular reason you're DC in the morning? I'm generally of the opinion that you clean as much as you need to, and DC twice a day seems a bit overkill and might just aggravate your skin in producing more oil since you're constantly stripping it of it.
My Naruko magnolia masks finally came in. The ear flaps are surprisingly comfy, I now wish all masks came like that since it's a very nice fit with no more dripping or flapping about the jaw area. Also really pleased with the results of those, think you'll like them too Aurora, ingredients and results wise. It's more of a creamy essence but very hydrating nonetheless, I had beautifully bright and surprisingly very even skin that lasted at least till the next day, it was very porcelain doll like. Can't really vow for the tightening aspect though. Ordered a few other singles now from Naruko alongside a box full of the Magnolia to see if there's more goodness where that came from at reasonable prices.
The Lululun Prestige Precious White/Gold masks also came in, I liked them well enough but still prefer the Red Prestige ones. I've actually been holding off purchases since the Japanese Yen went through the roof with market fluctuations carefully avoids bringing in the controversial B-word on this thread but do have plans to buy some things from Ipsa which is more of a high end/hi-tech brand from Japan. Had ordered samples for the Time Reset Aqua as a sort of FTE replacement as my Missha one is nearing the end. I liked the Ipsa one a lot and received another sample of the Metabolizer Extra 3 with it that really saved my skin from the weird dryness it's been experiencing with this odd weather. Lumpy, I know nothing of this 'heat' you speak of! 
Oh, another new find/discovery, I was looking into those Blossom Jeju petal masks that have a preliminary camellia oil step but had to rule them out for some ingredient or the other but I figured I can slap on a bit of facial oil (happened to have one high in camellia) before a standard sheet mask for pretty much the same effect and it's a lovely little extra treatment to perk up the skin. A sort of odd OCM-mask treatment hybrid.
Also finally got my act together and endured the sales pitch at DD, and got my hands on some lotion p50... it's safe to say it's love at first sight after only one use, the upside of having reactive skin is knowing when something is working pretty much straight away. They also had an interesting Vit C serum there which I was much tempted to purchase from Blissoma which sounds perfect for my skin but I shall buy it when I've finished the current one she says optimistically.
