Lustful Ruby is a cool, ruby ​​red shade that gives a deep, saturated color. If I want to create the “kissable lips” effect, I can apply it with a light watercolor technique, diluting it slightly with thinner.

However, when used in the lipstick effect technique, it retains its bright and saturated color, leaning towards cold tones.
Lustful Ruby is suitable for covering various failures in permanent makeup. It can also be used in the lipstick effect technique on bright and warm lips, but it is important to avoid applying it on cold lips, as it is a cold and deep shade.

It can also be used to saturate colors like Vamp or Siren's Kiss, just a drop of Lustful Ruby and the shade becomes even more saturated.
