UV White products is more for sun damaged skin as for White Lucent products are more for those who have spots and freckles. None of these two have the microbeads. Shiseido's Pureness Deep Cleansing Foam that has the purifying granules and another is the Pureness Pore Purifying Warm Scrub (this one you use once or twice a week) and contains microbeads and purifying granules.
Both UV White and White Lucent are good. It depends on what skin problems you have. If you have acne, you would be using the Pureness line, if you're young with no problems with your skin, then you would be with the Skincare line, if you're one that's mostly outdoors I would presume it's the UV Whites or Suncare line, if it's age spot/freckles then White Lucent, and last but not least wrinkles/aging skin etc. you'd be using Shiseido's Benefiance and High Performance skincare line.
I've been using Shiseido Products since my early twenties and have gone through most of their products as I got older. Now I'm with the White Lucent skincare line. Pretty soon will be with Benefiance and High Performance line(well, I can squeeze in some of their line:icon_smil ) I hope this helped.
