It can't be achieved without makeup! ! ! The masking paste is preferably "like a wipe". Apply the mask cream to your fingertips, and then apply a thin layer on the back to "erase" the original outline of your lips. The key point to grasp is that the upper and lower lip lines should be drawn on both sides of the inner corner of the lips, which is 1mm higher than the original outline. In this way, the lines of the whole lips appear smooth, making thick lips thinner. If you want to make your lips smoother, you can add shadows to the corners of your mouth with a dark lip liner.
