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

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.

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.

Expensive, but worth it.

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.

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.

Sad to see the over packaging from this vendor. STOP THE PLASTIC POLLUTION. Love the lip aid but not how it was delivered... no way could the product be harmed if it was just sent in a paper envelope.

We continue to buy this product for those pesky cold sores. It works.
