Thanks for the recommendation seb131, I’ll try that matte gel.
I currently use Aveeno, which gives a good matte finish and is great for the skin.
As for a decent shaver, I bought the Wahl Aqua Blade Multi groomer, which gives a close 0.2mm shave that blends in nicely with SMP treatment, or if you want a smooth wet shave look then use the foil attachment against the grain. Its not cheap though, around £99.
