This product may work for some but it doesn't for me. I'm overall sensitive to citric products, so this product turns my nails yellow. If you've noticed that citric doesn't work for your skin you may have a sensitivity reaction to this like I did. Otherwise it probably works for most people. With citric products most people must apply a sunscreen - well I can't apply sunscreen to my nails so this product just didn't work for me- waste of money.
