I know its kinda late to reply to this thread. Is the effect you're looking for is the "dewy" kind of skin with just a slight glistening effect? Not exactly just got out of the shower wet but slightly sweaty from the afternoon heat kind of wet? Because if its the latter, I came upon a tutorial like that a few months ago but I already forgotten the site. Fortunately, I saved the web pages and if you're interested I can send them over to you via email.
