generating buzz

A couple years ago, I joined a site to be what is called a Bzz Agent. When I sign up for a campaign, I usually get samples, and coupons from the company. I have tried some new things that impressed me. I joined a campaign that I ended up not liking once. The coffee mug I got broke a couple months later too.
How it works is you sign up, get your kit, and then try whatever it is. If you like it, great. If you don't, ok too. However, it is asked that we spread the word about things to others, with the requirement that we are to disclose that we are a Bzz Agent and we received coupons or samples. If we get coupons we are asked to share them with friends. Then we go back to the website and submit a Bzz Report, noting our conversations, and the feedback we get from the person with whom we shared the information.
I'm currently involved in a CoverGirl campaign for their NatureLuxe products, that use cucumber, jojoba & rosehip in the foundation and mango & shea butter in the gloss. So far, I like the foundation, but it's a sheerer finish than my regular foundation. I think when I picked Oak as my foundation color, I probably did get the right shade for my summer skin color. I haven't submitted an official review of it yet because I'm waiting to use it for a few days to see if I have any reactions to it. So far it's nice, feels very very light, but with a question mark. I need to up my water intake to make sure this microscopic itch is my own dehydration, or if it's a reaction to an ingredient in the foundation. I suspect the former actually. Ever since I lost my Flylady water bottle, my water intake went to nil because the other water bottles we own are not that great. This Bzz kit also came with a sheer lip gloss. I like how it feels, smells and the level of color. I'm not a gloss wearing kind of girl, so I am not sure if frequent reapplication is common, or if I am a freak of nature. (And no, you may not answer that one for me.) The Little (aka The Blur) came up to me yesterday when she saw me applying the lip gloss. She pointed to her mouth, saying "pee-yee baby!" (pretty baby). She wanted lip gloss too.
I will have to post again later to update my thoughts once I've concluded whether the problem was me or the makeup. But so far, I do like this, and may consider switching my foundation to this one. I was happy to see that both the lip gloss and foundation contain SPF 10 and 15 respectively. For me, that's a nice selling point, because I'm fair skinned (that whole Irish thing) and I don't tan easily. Plus I'm in my mom-bus a lot, and the windows only do so much. I like this SPF inclusion because the sunscreens I've tried previously make my face greasy, which in Florida heat (blast furnace really), that makes my face sweat more and feels gross.
If you've tried this, what do you think? Did it work for you? If not, would you give it a try?
