Quantum HealthSuperLysine+ Colds tick Lip Sunscreen - Lysine Herbs & Nutrients Soothe & Moisturize Lips - Softens & Protects from the Sun - SPF 21 - Clear - 0.17 Ounce

I have tried many other brands of lip balm but they each caused irritation and breakouts. I am glad that I discovered this brand several years ago. Back then, I also took the pills of the same name everyday to help with outbreaks. I don't take the pills nearly as frequently anymore but using this balm seems to be sufficient for me. I also have decreased my L-citrulline and Arginine (pre workout) usage, which I discovered to be extremely triggering. This balm is very moisturizing in a slightly petroleum jelly type of way, so there is a shine there after applying. I love this thickness about it because I don't need to use so much nor re-apply it frequently. I also use it in my nose because I have sinus issues which constantly has me wiping my nose with tissue. Using this has drastically reduced the level of inflammation that I used to have in my nose and eliminated outbreaks in there. I keep this stuff stocked and I have others now only using it, once they've tried some.

Cold sore prevention if used daily & great spf

This was super nourishing for my lips. I used the whole tube and It really helped my lips stay moist.

This product is great for those who are sensitive to the sun and get swollen lips. This product helps to prevent swelling in my lips when I go to the beach or have a day at a pool. Highly recommend!

Literally the only thing that stops a cold sore before they can even surface! And if it surfaces before you can use it, it stops them from growing instantly! Have been using this brand for more than a decade now. I have recommended it 100s of times over the years and everyone says the same-stuff works like magic!

Love this chapstick. Last long and not sticky.

Best lip balm out there... Keeps my lips from drying out and does not feel heavy or greasy... Love it's healing and protective effect

This is the only stick to have for cold sores! By keeping an application of this lysine stick on your lips during a breakout, you prevent that crack-heal, crack-heal cycle that prolongs it going away! I've read other reviews that some say they wear it all the time....that's okay too!
