Look no further than 'Renapur' a good UK product! See their website:
https://renapur.com/
I have used it for years ++ on all leather, including my shoes! A £12 tub (now reduced by 50ml to 200ml!!) lasts forever. Well, not quite as I have bought 2 over too many years than I care to recall!
I bought a '98 V70 a couple of years ago with full leather seats that were in need of some tlc. After a bit of black leather dye and working 'Renapur' into the leather the seats are looking maginficant. In fact I treated them again yesterday!
