Trial experience: I received PhiBi's face mask long time ago, and I specially tried it before writing the review. This silk protein face mask is ultra-thin. Usually, every time I open a face mask, there will be a lot of dripping essence down. But this face mask absorbs all the essence in the bag, and there is no phenomenon of dripping essence while using. Moreover, when I put it on my face, I feel that the skin around my eyes is cool and moisturized. The face mask fits well, with a nearly transparent color. I can even read a book while applying it, and don't necessarily have to lie down. I like this feature very much. Short peptide collagen, small molecule collagen, after using it, I feel like my skin pores are all open. It's a super comfortable face mask, highly recommended!
