I like Prada's Shielding Lip Balms and Exfoliating Concentrate, but after using this product I'm pretty convinced that sunscreen should not be marketed in monodose quantities. The balm and Exfoliating Concentrate are both reasonably sized and are good for several applications, but the Shielding Concentrate does not give you nearly enough per dose to adequately cover the face even once. Besides that, it's a bit hard to actually get it all out of the tiny tube, the scent isn't too pleasant, it's a bit greasy and I wish the SPF were higher. This isn't bad and I suppose it's a great size to stash in your purse, but I'm not impressed.
