The first one lasted almost a year and it's still my favourite lip mask. I've tried a couple others but this one is the only one that is neither sticky nor has a strong scent. It does have a scent - a little vanilla scent. Even in our dry summer my lips don't crack because I use this every night. 

I love this!! I use it every night and have noticed my lips are much softer and plumper! Highly recommend! I prefer this over the Laneige because the scent is barely noticeable (I believe it might be fragrance free) which is perfect for me as I dislike scented lip products.  

I use this every night before I go to bed and I'm still on my first tub (it's getting close to a year old I think). I've tried other brands and I like this one best. The scent isn't too strong unlike others I've tried and it's not sticky. My lips don't crack even when I use lip tints any more.
