This scary photo is not a cosplayer trying to imitate Jason Vorhees from Friday the 13^th or a Stormtrooper wannabe. Underneath the mask is renowned Hollywood actress and entrepreneur Jessica Alba, who is undergoing a LED skin therapy treatment session, reported The Daily Mail.

Alba was using the anti-aging LED facial mask Desse Opera Mask in an emergency treatment, she wrote.

The LED facial made by GTG Korea mask comes with three modes red, blue and white light for skin treatments, according to Food World News. The mask’s red light which has a wavelength of 630 nanometers (nm) is effective for skin rejuvenation, postcare after laser or Microneedle Treatment System (MTS), stated GTG Korea on its website.

Breakouts and zits can be treated using the blue light mode (415 nm), which is effective for acne and antimicrobial effects. For wound healing, skin rejuvenation and blood circulation of the skin, the white mode (830 nm) is most effective.

Even though LED facial treatments are gaining traction, it can be still fairly costly. The mask costs about US $3,000, wrote Belfast Telegraph.
