I have combination skin that gets dehydrated, especially around that very special time every month and a couple of times a week, my skin needs some Super TLC. I'm so glad that this is in Jumbo size. When I saw it on Socials, I was waiting for the announcement that it was here, I knew I had to get it. I started using it in March and bought my second tube to use in August. This product is a moisturiser, eye cream, treatment, mask all rolled into one. I use The Ordinary AHA + BHA, I use facial wax strips and, once a month, my face feels like it's going to melt off. These are the times I need to most soothing and Jet Lag is such a soothing product. And coming into winter, and rethinking my routine for the coming months, I knew JL was a must for nighttime hydration and the days when I needed an extra umph. Unlike another hydrating nighttime mask I use (and love) it doesn't leave a sticky texture on my skin. I know this product is going to last me the 12 months. One thing I will say is maybe find your groove with this product. I found that if I put on too much - the amount I would use for any other facemask - or put it on too soon after a facial oil, I get piling on my skin. I've usually used this product twice, maybe three times a week, and found that if I exceeded that, I wouldn't get the benefits after a point, but I've noticed in the last month I've been using it more. I can see, going forward, as the days get colder (I live in Ireland) I'll probably be using it four or five times a week. I don't know if you can tell, but I love this product.
