eli5 Why are there chemicals that can damage the skin instantaneously but not the other way around like improving it in a second

Question

Always wondered why acid attack works in an instant but there are no other chemicals (to my knowledge) that can heal or improve the skin instantly

Answer 1

Because damaging something is relatively easy but to “fix” skin you would have to find a way to speed up the healing process so that it is almost instant and that would require your body to do something it just takes time to do
