I'm a little skeptical about all makeup/skincare products, especially those that have a fake earth-friendly, natural public image--and those that fool you into thinking they're better because they're more expensive.
like just the other day I bought the banana shampoo at The Body Shop (super-green, natural-ingredients image, right?); not only did the shampoo have 5 types of parabens, it also had SLES and synthetic dyes/fragrance to fool you into believing you're smelling banana (which is a listed ingredient, but god knows the chemical treatments it goes through). not as bad as Lancome though--I can't find their ingredients ANYWHERE on their packaging or website, but 3rd party sources show that the $50 tinted moisturizer that made me break out wasn't any better than a drugstore equivalent.
I don't know what 99% of the ingredients in any given product are, so I don't sweat it too much--all the eco-hype is targeted towards towards a select few group of chemicals (parabens, sulfates, etc), but I'm willing to bet there are tons in everyday products that are just as bad. honestly, I'd rather have a decent amount of a good sunscreen w/parabens than a fancy small $30 tube of supposedly better ingredients.
