This bird's nest mask is basically a hydrating and nourishing mask making your skin baby soft after using it. Yes bird's nest might make you think of bird's spit but within Asian culture, bird's nest is a great ingredient for healthy skin and body. Asians make soup or drinks with bird's nest and they are not cheap at all. Indeed, it is a luxury if you can afford to drink bird's nest soup on a daily basis. On the other hand, My Beauty Diary makes this mask very affordable to the masses without compromising results. I don't know how much bird's nest is in this mask but this product definitely made my skin supple and soft while hydrating my skin. There is also leftover essence from the package that I like to put on my neck and hands afterwards. You should not omit your neck and hands in terms of hydration because those areas tend to age faster than your face!
