With some products, I know right away whether I love it or feel indifferent toward it. Others, like N.V. Perricone M.D. Ceramic Skin Smoother finishing serum ($75), take more time. I'm particularly fussy about pricey products. Even though some, like this one, are sent to me for review, I always think, "Would I buy it for this price?" And that's why it too me so long to write this review.

Like many of Dr. Perricone's products, Ceramic Skin Smoother contains age-fighting antioxidants and DMAE, which helps skin feel firmer. Although this serum is meant to be the last step in skin care before applying foundation, it's not strictly a makeup primer. It's much lighter than, say Smashbox Photo Finish, and it sinks into skin rather than sitting on top of it. Even so, I find that foundation does go on more smoothly over it; some people claim that they can go without foundation entirely with this product, but I prefer a little help. I love the lightweight, oil-free texture, and using it minimizes the look of my pores.

But let's go back to the "Would I buy this?" question. After I make my millions off of my Milo-endorsed gourmet pet food line, yes. Yes, I would. But for now, I have student loans to pay off, so I can't add this to my must-buy list just yet.
