A depilator or apparatus is a small electrical appliance for removing body hair, the depilator apparatus being designed to produce intense light which absorbs heat as the hair is black and less so as to heat and depilate only the hair portions. However, when the depilating device is used for polishing the skin, the depilating device still has thermal sensation or scalding sensation due to high light energy, so the anti-scald technology is required to be added into the depilating device. The department of polishing of traditional appearance that moults generally is provided with the ice and feels the head to carry out the ice compress to skin, and then improve user experience, alleviate ardor and sting sensation. However, the conventional method of contacting the skin by ice compress mainly has the following four main problems: first, the head is felt to ice of present mainstream is the transparent head that sapphire or glass made, and its cooling back temperature is too low just produces water mist and condenses into water easily, causes water to have water on the skin after water contacts the skin for user experience is relatively poor. Secondly, the light-emitting efficiency of the ice-sensitive head is reduced by generating water mist on the ice-sensitive head, and the sapphire can block about 15% of light, so that the light-emitting efficiency is further reduced. Thirdly, the ice-feeling head made of sapphire or glass must be used by being tightly attached to the skin, the light emitting is long, the fallen hairs can be stuck to the ice-feeling head, or the broken hairs can be stuck to the skin, and the user experience is poor due to the troublesome use.
