I just search in the internet when I want some information regarding beauty topics, but Im subscribed to RealAge.com when it comes to getting some infos about food and health.
About.com seems to have a lot of good articles on beauty, fitness, etc. I visit there a lot. Everyday minerals website has a beauty blog which is helpful not only with their makeup, but with any makekup. I found a lot of tips there.
I usually just do a search on the internet for what I am looking for specifically. As well I like to look at magazines every now and then to see what tips they offer. If you are not interested in purchasing magazines some of them will allow you to look at articles online if you register and you can go to your local library and read them.
