I got these Biotherm AquaSource Night Spa at Karstadt in Frankfurt from a Lancôme representative.
These samples had really good packaging, it opened up easy and evenly allowing the product to get out without wasting. The product has a very interesting consistency and formula. It is a really thick and sticky but nevertheless comfortable on the skin. I think it is a very interesting product, and I really liked it.
It feels like a cream for someone with really dry skin to use on top of a hydrating serum maybe. I for instance would use it only maybe two to three nights a week, on days that I feel my skin needs a bit of an extra, specially now that the cold has started. It retails for around forty something Euro, so it is not precisely cheap but also not an expensive moisturizer, somewhere mid-range.
Would I buy the product based on the sample? Yes, I am actually interested in getting this cream now!
