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.

My whole life I have struggled with canker sores on my lips every time I go into the sun. It usually happens every summer when I am on vacation. I take the lysine supplement, which helps, but have not been able to find a topical product that helps heal until I ordered this lip balm. It goes on smoothly, does not have an aftertaste, and soothes my lips. It seems to help with the healing. I will be a forever fan!

Cold sore prevention if used daily & great spf

Like this balm. Helps cold sores but does not prevent them.

I don't get cold sores but bought as a lip protectant & moisturizer during extreme hot & cold months. It works better than Chapstick. You don't have to apply on thick or heavy.

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

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!
