What happens when acetone comes into contact with my skin?

Acetone is either slightly irritating or not irritating, based on animal and limited human information. Application of 1 mL of acetone in a small glass tube to six male volunteers for 30 or 90 minutes resulted in only mild redness and swelling at 90 minutes
