I am an esthetician and want to understand the science. If OTC amounts of hypo. acid are so effective at killing pathogens on the skin by damaging the cell wall, etc., then why doesn’t it harm skim cells as well through the same mechanism?
In: Biology
It does.
Your topmost layer of skin is almost entirely old dead skin cells, which protects the live cells just underneath from some types of physical damage.
That slippery feeling when you get it on your skin? That’s the top layer of skin cells sloughing off.
If you kept your hands in undiluted bleach or related chlorine solutions for an extended period it would start to damage the tissues underneath.
