Hola!
This is such a mask month; I have masks coming out of my ears at the moment! REN masks, Good Things masks, Montagne Jeunesse masks, Alpha H Masks.  Just masks, masks, masks!  And here is another little beauty for you!
Just as I was thinking about more masks, I was asked if I would like to try the La Roche Posay Hydraphase Intense Mask.  Now, this was something I had to think about a little - my skin generally does not tend to need extra moisture, and if it does, I do slather on a layer of my Boots Botanics Face Balm and leave it on for a little while.  The more I thought about this mask, and read the press release, I found myself more and more intrigued, as it is specifically for sensitive/dehydrated skin, and I have been realising that my skin, though oily, is actually dehydrated: oily is my skin type, dehydrated is a skin condition that can occur with any skin type.  It is also said to soothe the skin, which seemed like a pretty good idea to me as I do use a lot of chemical exfoliants, and the old skin probably could do with a little TLC!  
Onto ingredients: I saw the words "Thermal Spring Water" and "Hyaluronic Acid Fragments" and that is the minute that I decided this is a mask I need to try.  Hyaluronic Acid is something found naturally within the skin - it plumps the skin, keeping it looking youthful, as each molecule is able to hold a huge percentage of water in comparison to its own weight.  As such, fillers are now using synthesised versions of hyaluronic acid to inject into the skin to plump it up, and Hyaluronic Acid is now available as injections in themselves, for a facial treatment in which the whole facial skin, or the skin on the back of hands are injected and plumped up!
Upon receipt of this, I had a little gander at the instructions, which suggest you apply a generous layer, let it sink in for ten minutes, and then tissue the excess off.  These instructions remind me of the Origins Drink Up Mask, which I haven't got around to testing yet, so I decided to deviate a little from the instructions and leave it on overnight.  The results were smoother, softer skin BUT I felt that the overnight treatment was a little heavy for my skin, so tried it again a few days later, where I applied it to my skin for a couple of hours whilst I worked on my dissertation - I found that this mask sinks right into my skin, it literally drank it up so there was no residue!  I then washed it off using an ordinary flannel, and was left with baby soft, very plump skin!  This is a lovelyyyyyy treat, whether a quick fix or as a slightly longer treatment.  It feels so soothing, but yet somehow quite active on the skin, and was a different experience for me as I usually stick to breakout fighting, or radiance-boosting clay or glycolic masks.  I feel it would be lovely after a hot day in the sun (with SPF of course), or just any time where your skin feels a little tight and just a little bleurgh in general: I also feel that sensitive or skin prone to redness would benefit from this little gem.
Overall, this is a very different to the masks I am used to, but nonetheless is absolutely a beautiful product with a high-end, velvety texture, and results to rival a good facial massage!  I would definitely purchase this myself, but I reckon my little tube will last me a good old while!
Hope you liked this!
