RealSelf.com, a Seattle-based site for user reviews of anti-aging products and treatments, has raised under $1 million from individual investors, reports Seattle PI. Investors include Zillow.com CEO Richard Barton, Revenue Sciences CEO Bill Grossman and Nick Hanauer, a partner Second Avenue Partners. While there are plenty of consumer product review sites, the site, which is officially launching today, is hoping to carve out a niche in an area where trustworthy information is hard to come by. Founder Tom Seery is a former executive at Expedia. Release.
