It is my second day using this and I bought it based on a sample used. I started out using Shiseido waterproof lotion sunscreens of spf of 38 or higher. Though I do find Shiseido very comprehensive as far as UV protection, I always felt that the lotions are wayy to chalky for my face and body once dried down, also it is a pain sometimes to take it off at the end of the day as you have to use some oil-based to remove all traces. Therefore, I will only use Shiseido sun lotions for traveling when high spf and coverage is needed. I feel that the Charmzone is good for everyday use and does the job just the same, except this sunscreen does not have UVC (for cancer). I actually got this as a sample first, and it does what it delivers: non-oily, makeup base, UVA and UVB (aging and burning), and according to the box improve skin elasticity. This does not leave my skin as chalky as Shiseido, just a perfect dry finish. I still do get some oilies, but at least my skin will not suffer dehydration. Smells good also. Bad side is it can be hard to find if you do not have korean based products near your city.
