I received a box of these samples in my rubybox and I must say that after reading the review here I went to try it out for myself. I have skin that looks dry but is actually oily with acne on my cheeks. It has rejuvenated my skin and I am very impressed. The sample sachets actually hold the serum in two separate pockets and you then bend the sachet in half and tear it open and dispense. Each sachet has enough product for me to use it twice on my whole face area but I am saving it for just around my eyes as I have already spent my quota for the month.
