From about 6 months after diagnosis, 6 months of low carb eating, my skin has really changed, and for someone my age it seems to be smooth and glossy - it heals well, having been paying attention only since diagnosis I don't know how much of an alteration that is, so I would recommend paying close attention to keeping BG levels normal - and perhaps try some coconut oil in the mean time. The oil works well as a hair treatment, and for cooking too, so any left over would not be wasted.
