The Mila Moursi Cyro Serum is a freeze treatment, which comes in a pack of eight cubes, meant to restore and rejuvenate your skin. The $155-product is described as a "spa-worthy treatment designed for at-home-use."
There are plenty of bizarre beauty regimes out there, each claiming to be the Holy Grail of anti-aging (anyone remember placenta facials?), so it's wise to take each new craze with a grain of salt.
Skeptics who are unsure that rubbing a glorified ice cube on their face will guarantee them youthful, radiant skin, need only to look into cryotherapy: a form of medical therapy that uses low temperatures to treat damaged skin tissue. Similarly, Mila Moursi's Cyro Serum uses the cryotherapy methodology to amplify circulation and stimulate aging skin.
