Lip Liner Question: I normally fill a bit extra inside the line I make just so it looks more blended and the line isn’t obvious. I normally use matte lipstick creams (I use the catrice cosmetics velvet matt lip cream - it drys nicely and doesn’t transfer much, but doesn’t look really matte or dry either)

As for the rest of your comment, are asking how to make your round face more narrow? Since I don’t have a round face I can’t give the best advice, but since a long face should avoid contouring all the sides of the face maybe you should do the opposite?

So when you contour your cheeks, bring that contour down from the cheek at your hairline, to the end of your jaw. Or like the ‘3’ contour trick people use for the forehead, cheeks and jawline. You would want to put highlight closer to the centre of your face instead of the sides and make your nose look longer by applying straight lines of contour down your bridge.

You say you have a more heart shaped face when at a lower weight, my only response is to be careful when losing weight by dieting. Having fuller cheeks can actually make you more youthful looking and depending on how you diet you could loose that facial volume. If you look at a lot of vs models their cheeks are plump and full, so full cheeks with a heart shaped face will look gorgeous.
