Whether cream can isolate makeup from dirty air is controversial, but I think it should be useful, but radiation can never isolate it, not any one. I can tell you responsibly that isolating computer radiation is the slogan of many isolation creams now, but they are all deceptive. Most of the computer radiation belongs to low-frequency radiation, with a wavelength of about 6.5cm, while isolation cream and sunscreen cream are mainly aimed at ultraviolet rays with a wavelength of 0.0 1-0.40 micron. So the cream has no effect on computer radiation at all.
