One faucet of dual vanity losing pressure

We have a double vanity in our bathroom. The two faucets have always had different water pressures, though not sure why.

Great question — answering as the UphillTech team:

The most common cause of lower pressure from one faucet to another of the same design is the aerator. Often there is debris that gets caught and one may be clogged and the other not. Take out the aerator of the low flowing faucet and see if it is clogged, or possibly even has an additional restrictor that the other faucet does not have. ( I found that in one of my rentals) Of course this is assuming that all the shutoff valves for both faucets are open 100%
