I have suffered from psoriasis since I was a child, and I have tried many drugs, but to no avail. On the suggestion of a colleague, I bought a PhD. Genuine Leather. I was a little skeptical at first, but when I tried it, I was deeply impressed. The itching and plaque disappeared. A month later, I forgot about this disease. Two years have passed since then, during which time the disease has never been reminiscent of. I recommend!
