I have been using this product for eight years, off and on. I tend to get bored, adventure off to something else that irritates my skin or makes me break out, and then come back to my Cetaphil. Especially good in the winter, when my skin freaks out and becomes dry and red (but still the occasional breakouts!). I also love the new packaging; the pump is much more convenient.
I have to admit I don't really understand the hype, as it didn't do anything for me. The "burn" sensation wasn't horrible, just kind of irritating, and I definitely didn't see any kind of difference in my lips. I see it as an expensive, tiny tube of clear lip gloss.
I received this as a sample from Sephora, and then ended up purchasing the full-size. I am half-Filipino (very tan during summer, but now during the winter yellow-based pallid tone) and this works incredibly well for me. This product makes my skin just look natural and flawless, and the SPF is an added bonus. Definitely will repurchase.
