I am a 22 year old female who for the last couple of years have suffered with darkening of lips. I suffer from eczema so i dont know if this is a contributory factor but i have periods where my lip darkens and but then goes away, only this time the lips is getting more pigmented and shows no signs of getting better. Please Please help me ive cried over this so many times because no seems to have an answer for it and its really starting to affect my confidence. Thank you so much for your time.
