The best ozonated oil! I've tried coconut oil, cocozon, aloe Vera gel etc. Nothing would hydrate my dry lips and dry cracking finger tips long enough, but Medcare ozonated olive oil lasts for a whole day even eating and drinking many times, my lips stays hydrated.! I've bought 3 of them and will send one to my daughter who always have dry hands and lips. At the beginning its smell bothered me a bit, but now I got used to it. Actually the smell is more of the ozon than olive oil because when my ozonator is on it smells exactly the same. I started to put it on my face every night for the winter, too.
