apply a deep moisturizer at night like Vaseline on ur lips, and in the morning brush ur lips with soft toothbrush, u will get rid of the dead skin and have pinkish lips. i tried it many times and it works. good luck.
Have a dermatologist (Dr. of skin disorders) check it out. Possibly getting permanent make up (lipstick)tattooed into your lips might solve the problem if the dermatologist doesn,t have a cure.Best of luck.
