loved this product initially ruined my nails though [SEP] i was initially in love with this polish i have been looking for a longer lasting uv free at home option and had all but given up when a friend recommended this product to meit goes on smoothly i love the brush it dries very fast looks great and lasts longer than regular polish i was tempted to toss all my old polish and replace it with thisthankfully i did not go all in right away after about a month of using it applying different colors approximately once a week i realized that my nails looked funny i honestly thought i had a health issue i soon realized that my nails were discolored yellowish from this polish it has now been about weeks since i removed the last color and i am still waiting for my nails to recover the discoloration is slowly growing out and my nails are super brittle i have never had a problem like this so i can only attribute it to this product i guess it is back to the drawing board
