I love this product and have ordered 6 tubes of Plexaderm. However, in 3 of the tubes the product has turned to liquid. The first one is used up because the liquid product spilled out too fast and too much. The second was going fast as liquid but then the plunger has malfunctioned and can't be used. The third is going very quickly. I'm afraid to open the next 3. The first question people have asked " was the product exposed to any extreme temperature changes"? The answer is no...it's always been in the home at a consistant temp of 68 to 70 degrees. I would appreciate having someone contact me about this problem. Anne Barry @ 978-340-6320
