I love the extra bubbles and the smell from the honey soap. I think (just my opinion) that maybe the honey adds a conditioning factor - my skin just feels smoother when I use it and I never have to add lotion afterward.
You didn't ask about how much to use, but I'll share that I learned a lesson the hard way on my last batch of honey soap (and it was a double batch, too!). I've always used 1/2 oz. of honey ppo and that's always worked great. With this last batch, the honey kind of just kept dripping out and I thought oh, what the heck, it'll be fine. I usually use a total of 4 oz. in a double batch like that but this was closer to 5 oz. total. So now I have some really pretty honey yogurt soap with a river of honey running through it! I wouldn't have thought that much extra honey would matter but it did. Pooled honey was in every single bar in both molds! I'll have to rebatch them. Others may use more honey and have good results, but I'll be sticking closely to the 1/2 oz. ppo from now on.
