If skin on hands is hard, peel.

One tea.sp. of apple vinegar and olive oil ads in palm, rub hands,as any skin damages will cure.
And one problem at garden is muscle stretched,as apple vinegar warm, does not dilute, wet towel flax, and apply on ache, wrap other towel and keep for 7 minutes, in a few times repeat, and for me cure at three times.

In sun burns rinse skin of apple vinegar in water diluted..
