This is the old version of Neutrogena sunblock mist, I suppose. Since it was on sale (buy 1 get 1 free) when I bought it at Watson at the end of May. Neutrogena Ultra Sheer Sunblock Cooling Mist (only) has SPF 30 but also with PA+++ (a.k.a. UVB protector), which protects your epidermis skin layer from darkening. In the other hand, SPF only measures how long you can stay in the sun without getting burned. That means, if you want to stay longer in the sun, you should re-apply this sunblock more often than when you use sunblock with SPF 50. It's also written that this product contains helioplex, broad spectrum UVA-UVB. From the Neutrogena site, I found that helioplex is an enhanced version of Avobenzone (which happens to be one of the best UVA blockers approved by the FDA). Since the avobenzone is unstable when exposed to sunlight, so Neutrogena has added Oxybenzone and DEHN to stabilize it and made better UVA blocker called Helioplex. (source: Neutrogena Website)
The bottle is made of aluminium and comes with a transparent plastic cap and sprayer. The content is 141gr and in Taiwan, the outer packaging is also transparent plastic box, which looks rather dull and cheap. I'm not sure if it can be used for face, but the bottle says: waterproof, sweatproof, non-comedogenic, oil-free and PABA free. But I don't bother to use it on my face, since I've got Neutrogena Ultra Sheer Complete UV Waterlight Lotion anyways. Some of the writings are in English, but mostly in Korean. I don't really get it why'd they put the writing in Korean when the products are sold in Taiwan.
This product is quite convenient to use, especially when you're out at the beach. You just need to spray it all over your arms and legs, then wipe it all over to even the liquid. And it is of course, cooling as it says on the bottle. It has cool citrus smell, but if you spray it too much, you will smell the alcohol quite heavy too. This is what actually the minus point of the product. I would suggest you to apply body lotion half an hour before applying this sunblock, so your skin stays moisturized as well as it's protected from UV rays. The sunscreen absorbs quite fast and well into my skin, and it only leaves very little bit of sticky feelings.
Overall, I rate this product 3.5 out of 5. The minus point is in the alcohol ingredient, which smells unpleasant and tends to dry out my skin.
