This Celimax noni ampoule has a slightly viscous texture but glides smoothly onto your skin.  However, if layered with other serums, it doesn't absorb as easily and your face does feel a bit tacky afterwards.  I bought it because the ingredients sound really good but I'm not so sure how they have helped my skin.  On the other hand, I've been using this ampoule for less than a month, so hopefully I'll see its benefits (for example, improvement of fine lines) after more consistent long-term use.  The packaging is really amazing.  It comes in a frosted glass bottle with an automatic pump dispenser.  The automatic pump dispenser is one of the best that I've ever used - it opens, draws out the liquid and closes the bottle beautifully air-tight.  Will decide whether to repurchase after using it for a longer period.
