I used 3 things and finished it beautifully.

Neutralize the lip line color with a lip liner. It looks too dark and makes my lips seem smaller, so I extend the line and fill it in. After that, I use a Hera tone-down pink lip balm to create a moisturizing and natural base.

For the finishing touch, apply a tint to the inner part of your lips and smudge it. It creates a beautiful, subtle gradient with a hint of intensity.
