A very special ingredient, Bird's Nest:
Bird nest is built by a special barn swallow residing around sea (collocalia fuciphaga) by mixing various seaweeds and bird's saliva. It contains various peptides and polysaccharides and used as "beauty food" from ancient China. It contains plentiful sialic acid that strengthens the skin barrier against the harmful external stimuli.

How to use: 

After cleansing, tightly apply mask on facial skin, following the contours of your face. After about 10-15 minutes, remove the sheet and pat face to absorb the remaining essence. Apply any remaining essence in the pouch to your neck and body.
