The Unique Shaving Soap from France

Osma Shaving Soap is truly a shaving soap unlike any other.   If another shaving soap contains alum, this is news for us.  Laboratoires Osma have true expertise with potassium alum from their fine natural deodorant alum stone lineup, and have incorporated that knowledge well here.

Just the Right Balance

Osma Rasage soap is not as slippery as Hitton, but that difficult/rewarding-type soap leaves all other concerns behind in the name of slip and wet.  It is not as thick and stable as Berthon, but it is still some well of each, and especially protective due that alum.  It is, in some sense, a practical Frenchman.

Contains Potassium Alum to Seal

This ‘Rasage’ Osma shaving soap with alum (potassium alum) in the ingredients is extremely unusual.  They also make the ~conventional ‘Tradition’ soap, but this was their first shaving soap.  Alum aids skin through sealing micro-cuts as they occur during shaving.  Indeed, this singular French shaving soap unequivocally achieves this odd trait.

Heavy Shea Butter to Balance Out the Alum

Adding alum (which makes everything more grippy) to a shaving soap formulation means there’s work ahead to achieve slickness and moisture.  Not to worry, the expert soapmakers at Osma have incorporated a strong basis of shea butter, and this soap as a result is plenty slick, when used correctly.  We invite you to critically read presumably-unbiased reviews of this soap here, here, here, … and anywhere else on the ‘net!   It has plenty of “haters”, but just remember it has been around on the market for quite a long time now, and wholly unaltered in its formulation unlike many others.

Long Wearing Milled Style

The Osma Rasage shaving soap has been purged of unnecessary water and air during the production.  When you buy water in a soap/croap/cream [these are all still soap to any chemist, remember], it may be easier to use, but the cost per use skyrockets.  Consequently, the Osma shaving soap Rasage is a true economical soap.

Splash with Hot Water, Load Fervently, Use in Hand

While the plastic reservoir is fine for storage, to make the most of this soap you should put a bit of very hot water atop it to soften the surface while in the shower prior to the shave.  Take the soap in hand and load with a wet brush held with knot partially skyward, and soap above.  Load until the water has been absorbed and the foam is rich and creamy.  You can use this way and still have a very economical running cost.
