Review (4/5): Perfect viscosity for face, a little goes a long way
The Terre de Mars oil serum is a nice emulsion made partly of primrose oil and caffeine with the purpose of brightening and hydrating the facial area for several hours. After each morning use of a few drops, my face is hydrated for the rest of the day and the moisture it provides is even more long-lasting in more humid/hot weather. Although not too viscous, it can become sticky if you apply more than necessary, so a small amount is enough to give your skin the desired effects. Also perfect for sensitive skin and it has a very very faint floral smell that is undetectable soon after applying.
