chemical- skin contact?
For corrosive acids, if a very small amount gets on the skin and causes a burn, and leaves a mark, is that mark permanent or would it take a very long
time to heal?

A small amount of sulfuric acid(concentrated) on hands. Small reddish blot, no openings or blisters.

But actually, you'll be fine... I think you can prob buy some ointment or salve or poultice or whatever if it bothers you too much. Hope it'll be
fine.

As long as your not messing with Hydrofluoric acid, most acids can be washed off the skin straight away with water and no real marks to the skin.
Strong Nitric acid can leave nice brown stains on your skin but they disappear after about a week.
Buying some nitrile or PVC disposable gloves when handling acids is a good idea if your worried but I don't think they will hold up to highly
concentrated strong acids very well.

Sulphuric dehydrates as well, which is why it's considered nastier than HCl for example.
As greenlight says, wear disposable gloves, or any gloves at all.
ALWAYS wear Eye Protection.
That small red dot on your skin would be a big Blind Spot if it had hit your eye.
OK. One of your eyes. Wasn't implying you're a cyclops.

Thank you all so much- i was worried that it would be worse than it really is, hopefully it disappears after a week or so.

Acids normally don't do much to the skin immediately, save for the more concentrated varieties. Even still if you wash them off quickly no problems
other than slight burns should remain.
At the end of the day, simulating atoms doesn't beat working with the real things...

Is it weird that I get a thin layer of concentrated sulfuric acid on my fingertips and hands pretty regularly, and all I get is slightly dry skin
afterward?

I have some concentrated Sulphuric acid that was initially 60% but i boiled the water off, and when I get that on my skin it doesn't really burn at
all and its washes off fine.
A couple of weeks ago I got some reagent grade 98% Sulphuric acid and accidentally spilled some down my hand (no gloves stupid) and it was extremely
painful seconds after it contacted my hand before I could even wash it off. It even left white marks on my hand where it spilt.
I think the grade of acid makes a difference. No Tears, is yours boiled down acid or is it brought as a high concentrated reagent grade acid already.

Mine is 35% concentration battery electrolyte boiled down to roughly a third of the original volume. I'm glad you mentioned that; I'll be a lot more
careful when I've bought some online.
