I have many health issues affecting my lips. For 3 years, my lips have been so dry, they crack and bleed every day if I don't care for them all the time. I really mean all the time, I cannot skip hydrating and moisturizing them for even an hour. It means bleeding and risking cold sores. I use some good oils with squalane often, but I need something more on top. This product helps a great deal if I don't forget to apply often. Simple chapstick or similar balms are not enough. This Extreme Lip Repair from Real Barrier is tick and nourrishing, it also protects my lips well. Will repurchase!
