Put raw aloe vera juice/gel (directly from a leaf of the plant) on sunburn before the sunburn begins to hurt and well-la! The sunburn won't hurt at all.
Yesterday I had been sitting with my back to the sun all morning and the back of my neck and part of my shoulders got badly burned. I didn't realize until my mom pointed it out; it hadn't started hurting yet. So we painted on some aloe goo, the leaf the paint brush, and I'm not hurting at all today! The burned area's a bit warm and the tiniest bit tender, but otherwise it feels fine! Now my only problem will be a funky looking tan: my pigtail braids cut two vertical white lines alongside my spine.
