A staple in my hydration layering process. Put this baby on a still damp and lightly wet face and it helps to slow down that TEWL (transepidermal water loss), and make sure you apply a moisturiser to lock all at hydration in. I would say this is a pretty good dupe to the Hada Labo lighter gokyujun and is more economical. A little goes a very long way, however I tend to add more layers for that added hydration. 100% recommend
