I am happy that you have found a solution for your concern. I too had a similar issue for a long time and tried similar remedies. As soon as I stopped the topical supplements, my feet started to get dry and cracked. So, I started to research the root cause of the problem. I found that healthy body doesn't allow such issues to happen. I also heard this saying as I was searching for a solution, "Disease and wellness can't exist in the body at the same time.'' Paul Chek. So, I concluded that when our bodies have adequate sources, we have good skin, are energetic, clear in thinking. I found Natasha Campbell's nutritional protocol called GAPS diet. I started eating this way about a week. Then, I realized that all the skin problems I had started disappearing. My heels got so soft and pink. I told my experience to my family. My mother who was a long time rosecea sufferer started the diet after about a month rosecea completely cleared. The only key is to follow this diet to the word. Little cheat food can stop the person from getting all the benefits.
I wanted to share this information so other people can benefit from it too.
