How noticeable is 0.5 ml lip filler?

During lip filler procedure

When you get 0.5 mL of lip filler, the change is usually quite subtle and natural. It will make your lips look a bit fuller, more defined, and more hydrated, but it won’t dramatically change their size. Most people describe it as a "your lips but better" result. You’ll likely notice a softer, plumper appearance, and your Cupid’s bow might look a little more defined too. If you already have fuller lips naturally, the difference will be very minimal. If your lips are thinner to begin with, you’ll see a slightly more noticeable, but still natural, enhancement. Keep in mind that immediately after the injection, swelling can make the lips look bigger than they will be once healed. After a few days, when the swelling goes down, the final result will look more proportionate to your face and very natural.
