Well that's hard to answer, but i think from the looks of it, a LOT. One works using laser to do god knows what, and the other uses LED lighting at particular nanometers.
THe palovia uses "laser" but it wont give specifics about the properties of it such as the intensity, wavelength, frequency and so on... so there's no way to know if and how it works besides taking their word for it (ive learned my lesson with listening to that while watching vague animations of it clearing pores and wrinkles that look identical to all the other wrinkle and acne animations out there).
But the quasar uses LED light... light that's at very intentional, specific wavelengths within the spectrum. Different ones have shown to have certain benefits (like 400-420nm, which is the common blueish colored ones, kills bacteria on and in the skin that causes acne, and then certain red ones like around 660nm can improve wrinkles and fine lines by increasing collagen production, and then greens are used for hyperpigmentation like freckles..etc.). Also, they give off no UV which means no cancer, which no one can say about palovia because their lack of sharing information.
There are lots of things cheaper but just as effective as the quasars (some come with 3 or even 4 colors and are more intense). A lot also come with blue and red mixed for even better results. So make sure you shop around. There's also ones that will look identical but if you read the technical stuff, you find out that the blue is 460nm, which isn't 400-420, but they will claime that THEY did a trial that said it was more effective (ehm, yeah Im sure), so be careful. You want to make sure it's a high intensity possible, with the particular thing you are looking for whether it's for acne or whatever, and that the nm is around the range you need. And you can also save yourself a lot of money by getting ones that dont need bulb replacements due to burn outs.
Some examples- BrightTherapy has one, so does Beauty Essence, Sirius, and Gmaher).
