in anti aging products, I'm wondering what ingredient(s)everyone
prefers in an "anti aging" product and why you like that ingredient?
Does anyone think "anti aging" products are a bunch of hype? There are
lots of claims out there and as Cindy pointed out there is a lot of
research going into skin care so just curious what people are thinking
about these types of products? Thanks, Sue
