Volufiline, drink fuck ton of water, brush your lips.
Also, Do this before going to bed as it will make your face look puffed. It is a simple stretching routine that has helped me achieve wider lips. Pull them as far apart as you can for a minute (extra hard for the last 10 seconds) and release. Do this 3 times every night. Then for about 30 seconds pull the top corner and the bottom corner of your lips apart (you shouldn't need much force), do this for each corner twice. It will take a lot, but if you're consistent every night you should notice results after a couple of months or even just a few weeks. This stretching routine aims to gradually widen the mouth by applying repeated mechanical tension to the perioral tissues, particularly the orbicularis oris muscle and surrounding connective structures. Consistent, controlled stretching may stimulate a process known as mechanotransduction, where cells respond to physical forces by remodeling tissue, potentially increasing elasticity and soft tissue length over time. This is possible since our mouth is one of the stretchiest tissues in our body ( this is why we can do so many different expressions with our mouth).
