Laneige is a koren brand which have a large range which i find is very good and very well priced. 

This hydration mask really packs a punch.  Its very easy to use.

After you had a shower and have cleaned your face you put the gel like mask on your face.  The mask feels like a water gel, which is very cooling and has no smell.

You just leave it on over night and wah la.. 

Compared to other mask where you need to wait for 20 mins and wash off this is the easy way where u can get some sleep and get the your skin fully hydrated and ready to go.

  I totally love this mask, i was having issues with winter weather all the wind and the heaters was taking a toll on my skin and putting on make up i can see the pores enlarged and the skin flaking.

Flaking skin and make up , really not a good look. I look like my face wanted to crack :( sux.

I religiously used this overnight mask for about a week and my skin was smooth and soft. Mind you it was so plum up and soft i feel like i had skin of a 5 year old or a baby that you just wanna pinch hehe .. :p

Foundation just guided on and break outs was minimized .

If you are still thinking over night mask might not be for you , as you might sleep on your side and have the gel all over the pillow there are alternatives.

They do make a normal mask which you put on for 20 min and then peel off.  Although its great but compared to price and results , this water sleeping pack/gel mask comes up on top for sure.

LOVE LOVE LOVE :p
