I just attended the International Beauty Show in New York City and spoke with a very informed representative of Gelish about this exact problem. I have used Gelish since it came out years ago. I have purchased just about every color that they make, so I have a vast collection of their polishes as well as other companies. Lately I have been experiencing the same problems with my Gelish polishes. The Hand and Nail Harmony representatives at the Beauty Show told me that Gelish only has a shelf life of 18 months and that I should not expect it to last any longer than that. WOW, REALLY? - than it is not a very good investment as I have many of my gel polishes for years with no problems - except for Gelish. I was pretty upset by this news, and then I visited the Akzentz booth and they told me the same thing - that their Luxio gel polish has the exact same shelf life of 18 months. Holy cow, I certainly cannot afford to be switching out hundreds and hundreds of dollars in gel polish on a continual basis.
Not quite sure what I think about all this. So, if you are using expired gel polishes on clients are the companies saying that there is some effect from this that we will notice on clients? If the polishes expire, why don't companies have an expiration date on the bottles? If the polishes sit around in their warehouses for who knows how long, why should we be purchasing old product with no expiration date available to help us make proper purchases of fresh product since gel polish is so expensive? I was never informed about gel polishes expiring before, but if they do - WE NEED EXPIRATION DATES ON BOTTLES !!!!!!!!!!!
