It should be ok for creams, but generally the smaller brushes aren't optimal for creams because they just can't hold a lot of lather. With soaps this isn't a big deal because it's trivial to add more soap between passes.I keep reading many people saying a Rooney 1/1 Super is better for soaps than creams.
I didn't say you needed it, only that they help. There are other reasons a small brush is better for soaps, such as dealing gracefully with those wooden bowls or old spice soap cups without slopping over everything. Can you use a big floppy brush successfully with soaps? Sure. I've done it many times. But it takes more effort and care than it does with a compact stiffer brush, and even then tends to leave more of a mess. To claim that a monster simpson can lather a puck of soap in a typical shaving mug or english soap bowl just as well and just as easily as a compact rooney finest or plisson HMW is just absurd.Same as "you need a small, dense brush for soaps". No you don't! It will feel different on the face, that's all.
It's the whole internet forum phenomena. 1 person will make a statement in 1 forum, a few people will repeat that statement, then a few more and so on. Eventually it becomes the gospel. Happens on almost all forums that I have visited. I'm even guilty of falling subject to the effect sometimes. I believe this is how humans behave in general but I'm not an anthropologist nor do I care to be.I've never understood this soap brush = face lather, cream brush = bowl lather mentality. I wish people would get past it. Same as "you need a small, dense brush for soaps". No you don't! It will feel different on the face, that's all.
I have bowl lathered soaps and face lathered creams successfully many times. A good brush with do both equally well, whether face or bowl lathering.
