Hi there...I can understand your concern. The cause for darkening of lips should be looked into. It could be due to increased exposure to sunlight, contact dermatitis, smoking, etc. Treatment will depend on the cause. So kindly consult a dermatologist for further evaluation and management. Avoid using any cosmetic products over it. It might exacerbate the pigmentation.
