If it’s just the faucet that’s leaking - it’s not a big deal. It’s often just replacing old washers or maybe a new faucet is needed. If it’s in the walls that’s tougher for sure.
It's doubtful there is anything in the wall that is causing a leak you would notice at the tap. Some faucets have a cartridge that is replaceable. Do you have a shutoff valve under the sink? if you are able, shut off the water supply. Open the faucet and make sure the shutoff valve is working and no water comes out. Old valves can corrode over time, get stuck, and not completely shut off the supply. If the valve works, disassemble the tap and take the pieces to a hardware store so you can match replacement parts. There are a lot of youtube videos that will show you how to do it. If all this sounds too intimidating, time to call the plumber.

To change the washer:
Hi! Most likely a washer or replacement cartridge. Look it up online and there should be a tutorial or video to help stop the leak. Good luck!
