there is thick skin from the right and left sides of my toenails that builds up under the sides of my toenails and then the nails become ingrown. there is also extra skin that grows from above my nail and into my nail. it builds up so much that my toenails protrude. I m pretty sure it s a keratin buildup, but I can t seem to get rid of it.I ve tried Kerasilk and other things like lotion with an exfoliator, but nothing seems to help. I wonder if I will always have this problem.
