I really liked this serum. It's lightweight, absorbs quickly, and doesn't leave a heavy feeling on the skin. The evening use feels nice. Plus for the handy pump bottle, which allows you to easily get the product without any mess. I can't evaluate the effect yet, as the testing should have continued for a longer time, but it already looks promising, and I believe the skin will only get better. But the skin feels hydrated and again of high quality from Lumenea, so at least in that sense, it works well. I would also like to try other products from this line - this was a good experience!
