Estee Lauder Perfectionist cp+ Targeted Wrinkle Filler is the new hotness to fill all those pesky little lines around your mouth from smoking all those years/in college/all the time up to like 3 seconds ago. Or just being old. Choose your excuse. This one is kinda lotion/gel textured so it feels soft, too. You can also use it on the massive divets in the rest of your face.
For a dryer thicker texture, this old stand by cannot be beat. Guerlain Kiss Kiss Liplift fills in line and creates a perfect lip line and keeps lipstick on longer. I use this on every bride. It does feel a little dry but the payoff is huge.
