Simple answer, yes. Be it the alcohol used is from pure ethanol group or fermented alcohol, it is not meant to be eaten. On bare hands, it’s going to evaporate anyway. For Muslim washing hands with tap water, has actually cleansed the remaining alcohol according to Islamic principle.
Can the skin absorb the alcohol and thus consuming the alcohol and making it non-halal?
The alcohol used in the sanitiser is industrial alcohol and not from liquor factory that produces for a consumer-alcoholic beverage.
Even the sanitiser oddly produced using liquor; liquor is the most natural way to clean. Use tap water and make sure no trace of colour and odour.
More importantly, the measurement of sin in Islam is all about purpose. The purpose is to clean and not to drink.
