I tried Optimera day cream and night cream for 2 days and on the third morning I woke up to puffy eyelids that felt like they had been sun burned. I had been excited to try the product and ended up very glad that I had tried it before wasting my money buying it. When I told the woman that had sent me the trial sample what happened she told me that I should keep using it because it was just my body getting used to it. Are you kidding me! I thought. I'm pretty sure a dermatologist wouldn't give anyone that advise if they had a reaction like I did. Since my experience last week with this product, I've been searching online for and finding so many terrible reviews for the U.S. version Nerium AD. I wish I had read these reviews before I tried the Optimera, because I wouldn't have even considered putting it anywhere near my face. I was lucky and my reaction was incredibly mild compared to some of the poor people I read about. I was also shocked at how many of these people were told basically the same thing by the people they got the product from...just keep using it, it's just detoxifying your skin so you need to give it 30 days. It's scary to think of how little these 'brand partners' care about the people they are selling this crap to just so they can try to make money and qualify for Ipads. She told me that if I wasn't going to keep using it to at least pass it on to someone I thought might be interested in it. I could not, in good conscience pass this on to some poor unsuspecting person after all the terrible reviews I've read about Nerium AD and more importantly the things I've read about the way the company treats anyone that tries to return product or cancel their autoship. Please people...before you even consider trying this...do your homework and read reviews by people that have had very negative results. If you still want to try it, at least you've been informed.
