PLEASE HELP: skinceuticals intense line defense

  1. After reading MUA reviews, I decided to replace my routine Estee Lauder ANR with Skinceuticals intense line defense. It retails for $52, which is expensive for me. So I tried eBay, hoping to find some better deals. Then I found some sellers selling bigger size of the product(2 OZ), which could not be found on Skinceuticals' website and other online skin retailers. The package is an amber translucent bottle, while the original retailer's 1 OZ bottle is clear translucent. I am wondering if any one here used or saw 2 OZ size package? Is it brownish?
  2. I cannot tell you if intense line defense works, but I can tell you that 1oz should last three months.
