what a cheeky product [SEP] i can honestly say that this was the first time i ve ever applied a sheet mask to my behind but i m always up for testing out new and inventive skincare items each product pouch contains plenty of hydrating essence and each of the two included sheet masks folds out to make a quarter moon shape it is definitely a bit challenging to try and place them by yourself since it requires trying to twist your body around to see a mirror but they d be super easy to seat properly if you had an extra handi will say that they do cling fairly well and the essence feels nourishing but the sheets ripple quickly with minor motions or movement if you re standing when you place them and then lie down on your stomach they shift around and lose some of their clinging magnetism causing little ridges and ripples in the cloth that are no longer in firm contact with the skin upon removal the remaining liquid essence does easily absorb so i didn t experience any post use stickiness or unpleasant residue but i m not entirely convinced the panthenol is a wonder ingredienti m sure the amino acid solution does firm tone and moisturize the skin to a certain degree but it s hard to really ascertain that after just one application and since each pouch contains just one pair of treatment sheets more of them would be required to determine if any noticeable benefits accumulated over time overall i think this is an intriguing novelty item that many consumers might find humorous so for that reason alone i think it s worth giving these a try
