Agree with JMH Zaino can make the leather glossy which is why I stopped using it even though I love the smell.
The advantage of leather masters leather protection cream matte is that it is a matte leather conditioner so it is easy to maintain the factory finish with this.
Swissvax gloss corrector matte is not necessary if you don't gloss up the leather. I have some but I don't use it since it removes oils from leather and shouldn't be used too often.
