Quantum Health Lysine+ Coldstick, SPF 21, 0.17 Ounces (Value Pack of 3)

This product has saved my lips from years of scars and fever blisters!!!

Great product

Seems to greatly accelerate the healing of cold sores; I don't know why. I suppose the Lysine is the most likely candidate, but clearly the FDA is not convinced, and won't let the mfr say that this product does much of anything at all. I suppose it works for some people and not others.

It works very well for Sun protection but can you all please add more product? The tube is only half filled and runs out quick.

Quick shipping and does exactly what it says. Helps to prevent cold sores in the sun.

I love using this chapstick. I think it’s very hydrating and makes your lips super soft.

This is about my fifth time ordering super lysine. It is the only one I use. It has a great consistency. Often, I will use it at bedtime. The SPF protection is an added bonus.

Heals cold sores fast. If you catch them soon enough they can be cured overnight. I highly recommend it, have been using it for years.
