1. Use pomegranate seeds.

One popular home remedy for lightening dark lips and giving them a rosy pink color is as follows:

Crush up the seeds of a pomegranate, mix the crushed seeds with some cold milk cream to form a paste, then apply this paste to the lips.
This should be repeated several times a week to gradually increase the pinkness of your lips.

2. Make a paste from turmeric and milk.

A paste made from a teaspoon of turmeric powder (a popular Indian spice) and a drop of cold milk is believed to remove lip discoloration, leaving lips looking healthy and pink.

Simply apply the paste to the lips and leave to sit for five minutes before rinsing off with warm water.
Do this every day for a week and you should notice a significant difference.
