disassemble bathroom mixer tap

[Nik Warren]

Hello,

I have a bathroom mixer tap which drips. I cannot see how to remove the valves as it is all smooth chrome. Would someone know how & what tool i would need please to take it apart ? I can send a photo if required.
Thank you and Happy New year....
