I'm thinking about booking a HydraFacial specifically for my enlarged pores on my nose and chin. But I've seen some places offer 'add-ons' like LED light or extra boosters. Are those actually necessary, or is the basic HydraFacial enough for pore cleansing? I don't want to be upsold on stuff I don't need, but if it really helps, I'll consider it. Also, does the suction part hurt? I've got sensitive skin, so I'm a bit nervous about the vacuum thing.
