I have been using this product for more than a month. I agree that if/when it melts and spreads to your eye, it burns like crazy! I just try to spread it thinner in light of knowing it will melt. It doesn't stop me from using it. I sent one tube to my mother (who is in her 70's) to use on her eyebrows. She uses Latisse on her lashes, but did not know what to do for her brows. She, too is delighted, and I will continue to keep both of us stocked up on this. My lashes are somewhat thicker, but they are noticeably longer and that works for me!
