Ive been using an alum block for months now and even though its works well for an alternative to an alcahol based aftershave i dont think it does much in the way of sealing nicks.The way i use it is after im done shaving is rinse my face with hot water rub the alum block on my face for about 20 seconds then cold rinse then apply the alum block for another 20 seconds all over the face then cold rinse again pat dry apply some trumper skin food but if theres any nicks there still bleeding.Any one else get this?,The kind of block iuse is osma but there all the same arent they lol
