For a cleanser I use one from Trader Joe's that has tea tree oil. It cleans great without over drying and doesn't leave my skin greasy either. Tea tree oil is a natural remedy for acne.
I like Lumene night cream. I also use Oil of Olay during the day and have for years.
I saw a report on that study mentioning that expensive creams did no better than the cheaper ones. There's no way to really know unless you do a 20 year study which is so expensive I don't think anyone would. But I suspect there isn't much difference. The study did mention that expensive products will have more exotic ingredients, like bees' testicles or whatever.

Okay, not really BTs.

So if you can afford those luxurious products then what the hell, why not?
