One of my favorite products is also by Ole Hendriksen, its the Truth Serum Collagen Booster
This product is absolutely amazing! Every ingredient in this product does wonders to keep your skin looking great, like sorting out wrinkles and fine lines Eww! Keeping skin looking radiant as possible, and keeping it nourished around the clock. So when I orginially tried this product, it came in a set of 3, inlcuding the night gel, this serum and moisterizer, Ive tried only 2 out of 3 products but its totes worth it!!
You can purchase it straight from the website http://www.olehenriksen.com/p-68-truth-serum-collagen-booster.aspx as well as Sephora.com!
