Best lip balm I have ever used.
By far the best lip balm you will ever buy. When I say I am addicted to Chapstick/lip balm it's an understatement. I don't just have one kind, in one place. I have multiple kinds (you never know what you're feeling or need) in every place! Like my cars chapstick has a chapstick family. I have been trying to pay attention to ingredients lately and realize how many awful chemicals are in most of the products I use. So...here we are, woke up after sleeping with a fan in my face and my lip was dry and cracked straight down the middle. Something so stupid caused so much discomfort I started immediately trying all the different brands, oils, balms, etc. Some burned, some made it worse, some did nothing. Two days of this nonsense and I decided to try this product. It was delivered the next day thank goodness because I was becoming so annoyed with the pain from a small cut. I instantly put the product on and my lip felt so much better. It lasts a very long time so it isn't drying back out and it isn't painful to reapply when needed. It's been less than 24 hours and my lip is almost better. I even slept with the fan on. This balm is amazing, made in the USA, comes in a huge tube unlike the other brands, costs is amazingly low, and it has no nasty smell at all! The only complaint I have would be my concern for my addiction to carry one in my pocket and due to the ingredients it will probably melt some but I will worry about that when I need to. Seriously, this stuff is so amazing I had to write this review. I don't know these people and I sure didn't get it for free. I will be purchasing more from them and sharing what a quality product it is. Just get it.

You will want more than one!
Nice size for lip balm, larger than small chapstick. It is smooth and hydrating. I have one handy in the office, my purse, bathroom, nightstand, etc. No commission here. Just love this product!

Great lip balm
I have had chapped lips for most of my adult life. This product has been the first product that I have used, where my lips are not cracked, peeling or dry. There is no smell or taste, very neutral. I had to use the balm frequently in the beginning, now maybe only several times a day. One tube last a long time I highly recommend this lip balm.
