I think for the price the block was a bit small and not really worth the money. It does the job but it's just as good to splash one's face with cold water.
It works! This stuff is a magical necessity!
Osma Alum Block - 75g
Never used one of these in my life, until now.
I suffer from razor rash pretty badly. I have tried various products from the high street and they hardly ever work. This worked almost instantly. It stings slightly when applied but nothing worse than a aftershave. However, I have not had a single issue with razor burn/bumps since using it. Just be sure to use it after using cold water on your face to really tighten the pores.
