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

In: Chemistry

Answer 1

Take a watch and hit it hard with a hammer. It will break instantly. However there is no tool that can instantly repair a watch.

It is similar with skin. Our skin is an ordered collection of individuallt complex cells. It is easy to break if the right chemical is applied, but hard to restore.
