The first time I tired this product was on a long distance flight with a total of 22 hours in the air. I have combination skin, and get really dry in areas on my skin when flying. I got a tester for this product, and decided to try it on the flight as I was gonna be sleeping and they told me it was transparent. So I got on the flight and removed my makeup and applied the cream all over my face. I was a little unsure if I should leave it on while I was sleeping, because in another review someone said that it would dry out your skin if left on for too long, whilst others have argued that they leave it on at night and get good results this way. I decided to leave it on as I don´t usually have problems with overall dryness. I was surprised how smooth the cream was, and I liked that it didn´t feel heavy on my skin. The fact that it is transparent makes it possible to not look silly while sitting next to strangers on the plane (I fly long distance several times a year). While having the mask on, I felt it was a protective barrier on my skin, and it felt amazing because I could really feel the hydrating effect in the mask. Since I dry out a lot on the plane, I could really feel the difference, and it felt amazing. When I woke up after 8 hours or so, I decided to wash it off because I was very curious how my skin would feel. I removed it with makeup wipes as this was the only thing I had at hand in my seat. I can honestly say that my skin was SO smooth and it really did what it is said to do, hydrate!! I put on a moisturiser and I couldn´t stop feeling my skin, because I have never tried a product that made my skin feel this way. Once I got off the flight and went into the city, the first thing I did was to purchase a full size of this product, and hope that it will continue to work well on my skin. I am optimistic, because if it can fight the cabin dryness, I am sure it will do well when my skin is more normal as well. It cost a little bit more than what I usually care to spend on any product, but I realise that I benefit from investing a little bit more in products that actually works. I bought this in Australia for AUD55. But when I come to think about it, it is not that expensive considering its recommended to use once or twice a week, so it will last for a while as to if it was for everyday use. If you are unsure if to purchase this product, go ask for a couple of tester packs to try on, everyones skin is different, and I can tell by the reviews here on makeupalley that some are really happy with this product, while others do not like it at all. So to make sure you get something that is right for your skin, it´s better to try it out at first.
