As has been stated, aside from open wounds, lead cannot get through the skin. Drinking, eating, or smoking with leaded up hands IS a good way to ingest it.
Best protection is simply not to eat, drink (or smoke at all, come on!) in the reloading area. At all. When you leave, wash up immediately. If in an unfinished basement, install a hand sink.
Gloves are NOT a protective measure in themselves. They only work as a barrier that gets contaminated, then you remove them before you touch other things. For example, before you leave the reloading room, instead of washing you strip off the gloves (and discard them somewhere that won't be touched! In a bagged can, keep following procedures all the way down!). That way, hands are clean.
Some people wear dust masks, and they can be suggested, NOT as a protective measure, but as a reminder. You can't eat or drink with it in the way. If you find that you keep catching yourself not following contamination protocol, get a box of dust masks and use them until you get used to it.
I also agree it's pretty unlikely you have serious lead issues from reloading. Casting is #1, and otherwise it's gonna be from firing. Indoor ranges are the worst, but outdoor can be.
And then: same procedures. Lead or lead-compound-bearing dust is on everything. Including your guns. Wash after shooting, do not drink/eat/smoke on the range until you have washed up. Think about what else you are touching. Your bag, your car? Wash before you touch that stuff. Effective wipes for this purpose exist, so that may be the way to go if the range has no good wash facilities.
For high lead levels, start monitoring. That means at least every 3 months, get tested. Then, once in a good place, annually for the rest of your life to make sure it doesn't happen again.
