It seems like a nice hydrating product. Unfortunately the sample is mostly one time use so I can't tell longer term effects.

After using this, my skin felt smooth and clean. Highly recommended

Biotherm’s Powerful Life Plankton Elixer was a game changer in my daily facial regimen. My face has never felt more smooth and plump!

very good for my dry and sensitive skin, I didn't have any allergy reaction to this product. It moisturizes the skin.

This is a nice produce sample that went on easily and did not leave any film all of it until it dissolved into the skin. It also made my my skin smoother and softer for a few hours. There was a gentle scent but not overbearing.
