i love using vitamin c in my skincare so i gave a try to those masks. comparing to innisfree's real squeeze mask, skin clinic is very different. first, when you pull out the mask it has a protective film that makes it easier to unfold and apply the mask. then the sheet material is so good, like it's thin, but it fits the face well (i have rather 'european' face with big nose and generally my face is big, so many masks need some cutting and adjusting from my side). the essence isn't greasy or creamy, it's watery and feels super fresh on my face. and what i liked a lot is that before applying the mask i did face peeling and once sheet touched my skin i felt a slight tingling - exactly the same one when i use my vitamin c serum! what's more this mask is packed with extracts and oils. you can find here:  Citrus Paradisi (Grapefruit) Fruit Extract, Citrus Unshiu Peel Extract, Orchid Extract, Camellia Sinensis Leaf Extract, Camellia Japonica Leaf Extract, Opuntia Coccinellifera Fruit Extract, Citrus Aurantium Dulcis (Orange) Peel Oil, Citrus Medica Limonum (Lemon) Peel Oil, Lavandula Angustifolia (Lavender) Oil, Abies Sibirica Oil, Mentha Piperita (Peppermint) Oil, Eucalyptus globulus Leaf Oil, Juniperus Virginiana Oil, Eugenia caryophyllus(Clove) Leaf Oil (taken from the ingredients list). plus, there's also Niacinamide (4th place in the ingredients, so it's pretty high) that is basically the ingredient that makes your skin beautiful since it whitens, moisturizes, helps to heal all the little scratches and thanks to it skin doesn't become greasy too fast. overall, this is very good mask that leaves skin moisturized, fresh and you feeling pampered!
