I have regularly used this kit as my travel go-to! Towards the end of my long-haul flights, I use the eye masks to help by relieving signs of fatigue but also, the effects of flying followed by the booster just to give a that extra boost that can be need when you might not be ultimately hydrated. Now that the you can get a full face mask version of the 'sub-zero de-puffing' collection, I'll certainly be adding them into my little travel kit for future travel too!
