“Lipstick effect” technique will give you a more saturated colour, more defined shape and will look like you are wearing sheer lipstick all the time. Colour can be light and natural (which will give you more options if you like to wear a different lipstick colour over the lip tattoo sometimes) or bold and bright (pinks, reds, etc).
Since the pigment is more saturated this technique will last longer than a lip blush tattoo.
Can last anywhere between 1-3 years. Annual touch-ups are recommended every 1-3 years to keep the colour looking good.
