The skin refresher is a very nice touch. It's a vaporizer with nice Jeju water, neutral in scent. Very good to avoid dry, cracked skin on long flights and it doesn't get oily or stinky. It's a seriously nice amenity. I wish more airlines provided something like it.

In comparison, United's was a bit greasy and I wasn't keen on the scent. IIRC, SQ has something available in some of the lavs that's pretty good.

Word to the wise: I've snuck into the designated "women's" restroom at the back of a KE 744 in long-haul economy and found the Jeju vaporizers in there, when they're not in the other lavs.
