I just joined mySkin yesterday, and I had a really good time playing around on the site. It's not just your typical review site - you can keep track of your daily skin conditions and use of products, which is really helpful if you're trying to track down a reaction to something. Enter in each of the products you use, and it will give you suggestions based on your profile and current product usage. It suggested a few things that I hadn't tried, so of course I'm off to give them a whirl.
I told you - I'm addicted to skin care!
I have a special invite code for you - just enter "retrodivasbeauty" in the invite area. You have to have an invite code to join, so be sure to use it. Definitely go poke around and tell me if you like it!
