The sample size bottles are value for money compared to its bigger counterpart. On top of that, I find it more hygienic to use as each bottle has less time exposed to air. It's convenient for travel and I always bring one with me when I go on flights to cleanse and moisturise my face on long flights.

I'm not sure if I'm going to buy the full size! But this one is so perfect! 

useful for who wants to try the sleeping mask!

I will buy the full size for sure
