Full spectrum sunglasses and not smoking will limit the crows feet. Unfortunatley nothing you rub into them will do anything but temporarily soften the look. Your regular moisturizer, if unscented, should do the trick. If you need depuffing, nothing works better than preparation H gel. If you want to make lines appear softer with optical diffusers (little mica bits) L'Oreal, Aveeno, Ponds, and Olay Regenerist make such products.
