Comments on: Nano Technology in Sunscreens: Naughty or Nice? http://thebeautybrains.com/2007/10/07/nano-technology-in-sunscreens-naughty-or-nice/ Cosmetic chemists answer your beauty product questions! We are a group of cosmetic scientists who understand what the chemicals used in cosmetics really do, how products are tested, and what all the advertising means.

The penetration of sunscreens into your skin is not a significant contributor. Wrinkles are caused primarily by sun damage, aging (loss of collagen/elastin), and gravity.

I find them very effective and they do not irritate my skin at all plus they are not heavy and greasy like a lot of zinc based sunblocks.

(at least I hope so). I'd be interested to see what the brains behind the Beauty Brains (apparently I've never met a pun I didn't like) think of the sunscreen choices at 3Luxe - http://www.3luxe.com/category/Health_and_Beauty/Sunscreen I personally use the Neutrogena one, but I'd be interested to know if it was worth splurging on a more expensive one (My pallor would make Casper jealous and skin cancer runs in my family, so I'm willing to spend more if something is amazing and protects my skin really well - an ounce of prevention and all that).

I thought you rebuffed that chemicals are absorbed into the skin per all the conversation about "5lbs of chemicals." And isn't Ti02 a chemical? And the product to stop the free radical damage is a natural product from grape seeds? So if that's the case, if nano sized ingredients are delivered in plant based spheres, are they being absorbed by the skin and helping?
