Hi Sarah,
I am sorry that your last post didn't get any replies. Sometimes we miss a few but it is not intentional
As for the supplements that might help with thickening the skin I have no clue but a lot has been posted here regarding grape seed extract and pine bark for strengthening capillaries. For me I believe it does help somewhat. I am taking 1 grapeseed tablet a day. It is Trunature and 150 mg. I bought it at Costco.
If you do a search on grapeseed extract you will find more info on it.
Best wishes,
Melissa
