Hi. I used glycerin for quite some time when my psoriasis was severe. It worked wonders for relieving flaking, and from this perspective alone I highly recommend it. But it didn't affect my psoriasis at all, and I subsequently abandoned it when my psoriasis eventually improved due to other measures (diet, supplements). However I recently started back on it after, like you, seeing remarkable testimonials (with before/after pics) of folks who've fully cleared their psoriasis in a short time courtesy of glycerin. I am hoping it can help clear a couple of remaining stubborn areas on my feet. It's way too early to see results.
