How can I treat the damage caused by the lip filler "kopolymer polyacrylamide" that I had 20 years ago? My lips looked perfect for the first couple of year. Then after 3 years it started forming bumps but it was still normal. Until 10 yearss ago the colors of my lips started changing and the borders became uneven in shape. If i put lipstick they will look normal but without i can see all the damage. Im sure there should be a way to treat them considering the technology we have now.
