How will I cover my face and not stain bed linens? Will it cause compensatory sweating elsewhere? Can I use regular deodorant on my underarms while I am using drysol on my face and scalp or do I have to use Drysol there too? I do not have a sweating problem with my underams. Should this only be used as a short term solution to facial and scalp sweating(I am attending a wedding) or can it be used long term?
