I'm a huge Renee Rouleau fan. In fact, I just went to her spa yesterday to get more product. I'm a single mom, but I do only use Renee's products - and my 10 year old daughter is a model and SHE is begging me to get her Renee's face wash.
I like that there are 9 skin types and each type has set products. So I started out purchasing the entire package for my type - and now I just replace what's running out - so in reality, you're not dropping a lot of money except for the first time to get all the products.
I've been using her products since last summer, and I can tell a HUGE difference in my skin. I don't even get the once a month blemish any more.
I also use her liquid mineral makeup. Prior to that I was using MAC studio fix. Renee's product - I can apply in the a.m., and no powder, and it lasts all day and doesn't get shiny at all. I used to always have to touch up or powder. She doesn't sell that on her site, though - so if you live in the Dallas area, you can get it.
