This premium quality French Osma alum block will help sooth irritation and razor burn after shaving. It is an all-natural astringent that will stop any small nicks or cuts from bleeding. It is a crystal-like stone that is moistened with cold water and gently rubbed over the entire face to act as an antiseptic. Leave it on for a minute or so, then rinse it off with cold water.

Not only does it aid in soothing skin irritation, but the properties in the Alum block ensure that the hairs on your face grow straight out from your face and neck, which prevents ingrown hairs.

A must have for shaving

This product is fantastic for soothing the skin after shaving, I have used it for shaving my head bald and really soothes the skin preventing irritation. The best thing though is it closes up all nasty cuts seals the skin. Fantastic product and thanks fineshave for being excellent to deal with.

The skin heals

The Alum block really heals my skin after shaving. I suggest after applying the alum block give it a few minutes then wash it off. Dry your skin and apply a moisturiser.

Okay, I get it now

First time user an hour ago. Instantly soothes the skin leaving a grippier, tighter feel after rinsing.
I will be using it after every shave. Now it's just part of my shaving routine. Get some and use it.

Eric B. (Auckland, New Zealand)
A valuable addition to the routine

Used as instructed it made the usual couple of blood spots vanish and the skin squeaky after washing off. I noticed the proraso green aftershave had a much more noticeable cooling effect as well. Really recommended, especially since they apparently last forever.

Scort C. (Auckland, New Zealand)
Brilliant !!

Have tried other lotions and methods to stop shaving cuts and nicks. This is the ultimate. Easy. No mess and stops cuts instantly! I was surprised how effective it is. A+++

I don't think it's any different from the cheaper alums, but it last forever so eh

First alum

Great product easy to use, stop nicks from bleeding and gives feedback on where you shave too close to the skin. Not sure how others stack up but I'll probably buy this one again.
