When I use these on my face, do I have to use them as the whole grain mixed with a bit of water ? Is that the only way that they will cleanse the skin ?

Or will they be just as effective if I blend them with a food blender into like a paste ?

My facial skin is hyper HYPER sensitive and I find the coarse, un-blended oats too scratchy and irritating. So if they're just as effective in the mushy pulp version, then that would be better
