Hi, today I had a first time client come back to me with her nails turned brown. She had had a french manicure with gel polish under a LED lamp. She flew the next day, and noticed it starting then. She has not used any liquids or lotions on them, the only thing she had taken with her were face wipes. This has never happened to me before and I am seeing her this afternoon and I am hoping someone might have some ideas as to why it has happened. TIA xx
