Pterygium results from abnormal growth of damaged skin. The eponychium is living skin that surrounds the base of the nail plate and the cuticle is dead skin on the nail plate. My book breaks this down into understandable terms. If you're interested in this type of thing, you should get a copy, Nail Structure and Product Chemistry. Sweet Squared carry's it.
I hope that answers your questions.
Hi Lana, I am comming to you with a new problem. I amtrying to put a very thin piece of paper on the nail that has a really cool design. I have wet the paper with monomer and tried to put it on gel, and wet acryli. I have also tried to glue it with 4 different glues. My problem is that the nail inquestion is a high arched nail, and I always have puckers!
