I was diagnosed with Keratosis Pilaris on my arms many years ago and have tried many remedies to get rid of the pesky bumps. Recently, I have started using plain witch hazel (the cheap stuff from the pharmacy) on my arms. Amazingly, the bumps seem to recede. The redness hasn't really gone away but my smoother arms are a vast improvement. I've read about a mixture of witch hazel, alcohol, and aspirin being used for ingrown hairs so I might try this as well to see if I get any different results. I'll update later on my progress!
