It's value in price, HK$180 for such a big piece of hydrating mask. It really works no matter summer or winter and I use to use it when I'm taking shower. But the super hydrating effect gradually gone when I keep using it for months. The skin seems getting used to it. It happens on my sister too. Thus now I'm still using it, but after finishing half bottlle, then I use Avene hydrating mask instead. After not using Origin for a while (2-3 months), swab to Origin again, the effect is still excellent!
