I want to lighten the colour of my my lips. My lips are naturally darkish purple, top lip, and dusky to ligth pink, bottom lip. It's a hereditary trait and one that I share with my mother's side of the family. Can I do a treatment to lighten my lips? I have done herbal at-home remedies (honey, milk, lemon, beetroot) with varing sucess but it takes weeks to months to show any improvement, quite effective but I'm not determined enough to do the herbal treatment daily. Please help.
