Wherein the skin treatment device may be used with a depilatory and/or a skin rejuvenating device.

In this embodiment, the heat conducting member 210 transfers heat generated by the components in contact with the heat conducting member to the fin assembly 220, and the blower 300 blows air to the installation cavity 101, so that the heat of the fin assembly 220 and other positions in the installation cavity 101 is taken away by air flow. Specifically, after exchanging heat with the heat sink assembly 220, a part of wind in the installation cavity 101 is blown out of the housing assembly 100 from the first ventilation opening 103, and the other part of wind enters the heat dissipation cavity 102 and is blown out of the housing assembly 100, in the scheme, the installation cavity 101 and the heat dissipation cavity 102 are both used for heat dissipation, the heat dissipation space is large, the contact area with the components in the housing assembly 100 is large, and the corresponding wind outlet area is also large, so that the heat dissipation effect of the skin treatment device is enhanced, and the comfort of a user when using the skin treatment device is improved.

Wherein, optionally, the heat conducting member 210 has capillary heat conducting channels to improve heat conducting effect.

Wherein, one end of the housing assembly 100 has a light outlet 104, the heat dissipation cavity 102 is located between the light outlet 104 and the installation cavity 101, and the fan 300 is located at one side of the installation cavity 101 facing away from the light outlet 104.

For example, when the IPL has a wavelength of 690nm to 1200nm, it is mostly remote to have an epilation effect by photothermolysis with intense pulsed light; since melanocytes in hair follicles can selectively absorb light of a specific wavelength band, and IPL light can penetrate epidermis and directly reach into hair follicles of dermis; the light energy is absorbed by melanocytes in hair follicles in dermis and converted into heat energy, raising the temperature of hair follicles; when the temperature of the hair follicle rises to be high enough, the hair follicle structure is irreversibly destroyed, and the destroyed hair follicle naturally falls off after a period of time, so that the hair growth is delayed or even the extension is stopped in a short period of time. IPL has a skin rejuvenating effect mainly when the wavelength of IPL is 560nm to 640 nm. Alternatively, the light emitting assembly 400 is a laser light emitting assembly to generate laser light to achieve depilation by laser light.
