The Aesthetic Nose gives a pawn that's been implanted with it a bonus of +1 to beauty, corresponding to +20 opinion from other colonists.
Aesthetic noses can be made at the fabrication bench, after the Flesh Shaping research is completed. This research requires the Flesh Shaping techprint to unlock. Crafting the part requires 10 Plasteel, 2 advanced components and 26000 unit of work. They require a crafting skill of 8.
The aesthetic nose both improves the beauty of the pawn and replaces a missing nose. Thus, it is useful for social harmony by keeping opinions high, both by the +20 of having +1 beauty but also by avoiding the "Disfigured" opinion penalty a missing nose creates. This bonus and removal of a malus can be also help couple up a particular pawn or keep an existing couple together and happy by increasing their opinion of each other.
The Gastro-analyzer and aesthetic nose cannot be installed on the same pawn.
Gastro-analyzer is an implant INTO the nose, while aesthetic nose REPLACES the nose. You can't install a gastro analyzer into a aesthetic nose; it's one or the other.—Tynan Sylvester
This is the only part incompatibility meaning, besides Wealth, there is no reason not to install this part on non-cooking pawns. However its small effect also make doing so a low priority.
There are conflicting reports that beauty improves Trade prices, but these are currently unconfirmed.
