A salt lamp that feels damp to the touch, or occasionally leaves a small ring of moisture on its base, has not malfunctioned. This is a normal property of the material, driven by humidity in the surrounding air rather than anything wrong with the lamp itself.
Salt is hygroscopic, meaning it naturally draws moisture out of the air around it. In a humid room, that moisture collects on the crystal's surface and, once enough has gathered, can run down to the wooden base below. This is the same property that makes salt useful as a food preservative, just showing up in a less convenient way in a decorative object.
The fix is usually simple. Running the lamp for several hours a day, ideally including overnight, keeps the crystal warm enough to evaporate moisture before it builds up. In consistently humid rooms, a dehumidifier or simply relocating the lamp to a drier spot in the home addresses the underlying cause rather than just the symptom.
A small dish, coaster, or waterproof mat under the wooden base is a sensible precaution in any room prone to humidity, since it protects furniture from water staining regardless of how well the lamp itself is managed. Some lamps ship with an absorbent pad for exactly this reason.
Occasional light dampness is normal and not a sign of a defective lamp. Consistent, heavy dripping even with the lamp running regularly is less common and is worth raising with the retailer, since it may point to unusually high humidity in the room that is worth addressing on its own terms, separate from the lamp.

She has spent years writing about home decor and natural materials, and started this site after noticing how much confusing, overstated information circulates about salt lamps. The aim here is simple: honest buying advice, practical care tips, and a straight answer on which claims hold up and which don't.
Salt is soft and absorbs moisture, which means care for a salt lamp looks a little different from caring for glass or ceramic decor.
