It's called Swissvax Leather Healer.
This product is specially mixed to match the exact color of the factory leather at the swissvax factory. Each bottle takes 3-4 weeks to receive from Switzerland.
We applied it to the Coral red Boston leather found in this BMW 135i we recently detailed.

The application process is pretty simple, and leaves the seats looking new!
See for yourself...
Products Used:
Swissvax Leather Cleaner
Swissvax Leather Brush
Swissvax Leather Grinding Pad
Swissvax Leather Healer
Swissvax Leather Glaze (Leather Sealant)
Here's how the seat looked before:
First we cleaned the surface to be treated and grinded the frayed leather using the grinding pad. then applied the Leather Healer. We ended up applying about 5 coats with about 30 min between each coat.
And the finished result!
Thanks for looking!
