A nail care device includes a covering part, a light-emitting component, and a light-emitting control module. The covering part is configured for covering a tip of a digit of a limb. The light-emitting component is disposed in the covering part in a manner that light emitted by the light-emitting component irradiates a nail on the tip of the digit covered by the covering part. The light-emitting control module is coupled to the light-emitting component and is operable to control operation of the light-emitting component.
