Lots of remedies. Try any combination of the following.
T-shirt.
Sun-Block.
Stay inside.
Stay under cover of tree or bimini top.
Move way up north.
Just kidding...I feel your pain. Literally. I got baked last weekend and still tender to the touch, and peeling. Luckily, I got my good base tan under the peel, and didn't lose all my color when the skin came off.
I am still a prime candidate for skin cancer, but at least I look good (or will when I finish peeling :ack
.
I always burn the first time out each year, then not again the rest of the year. I have lots of Indian (Native American) in me, and tend to tan up pretty well.
Remedies after the fact? Not much you can do. The damage has been done. My wife uses an aloe/lidocaine product to numb the skin out. I just shower in warm water to open the pores up (yes, it hurts) then quick cold shower at the end, then wipe down with baby oil while still wet, towel dry off, and drink a beer. Keep hydrated as much as possible.
