Review (4/5): the mask is quite nice, tingley
I bought this product because it seems gentle and is cruelty free/vegan. I was shocked to see silk protein in the ingredients list when I got the product, but the company assures me although they are called "silk proteins" on the label, the ingredient is not animal-derived and is comprised of "amino acids developed from plant proteins and carbohydrates" (which I don't think should be called silk then) so I decided to try the mask. One star off for confusing and untrustworthy labeling.
That said, the mask is quite nice, tingley, and I had pleasantly soft skin afterward. The mask is gel-like and about the consistency of toothpaste, but goes on clear. I applied toward the end of a bath and left it to dry before rinsing, it dries to a slightly tacky but not tight finish and is relatively easy to rinse off. All and all, I would give it five stars if I didn't wonder slightly about the labeling issue.
