Very nice serum. It calms my even super irritated skin in seconds. It actually have a prolonged effect so you can say it do restore the barrier. Just after 3 time of use my skin was calm for a month in a row without using this ampoule.

The packing is very light as it is plastic, but still looks good (it actually looks like glass until you weight it). Easy to use. The texture of the serum is suitable for pipette.

Smells like nothing (very light smell or raw materials). Absorbs very quickly leaving skin soft and moistured without greasy feeling. My skin is super dry, but I think this ampoule will suit people with oily skin too. 

It's nice for hot summer too (for winter it can be layered). 

Overall it is must-have for anyone with sensitive skin.
