I’ve only applied 2 very temporary applications and it’s already working before it’s even developed. Thanks so much! Great product, thanks so much!

I think I found the holy grail of OTC coldsore Tx. I am SOOOO happy I found this at SDM. It appears to be a new formulation and doesn’t contain the same medicinal ingredients as other cold sore treatments I’ve used (both OTC and Rx). The product is produced in the GTA, which makes me like it even more. I used it for the first time this morning when I first felt a cold sore tingle. It’s now 5:30pm and it appears that the cold sore is not going to breach my skin! I also like how the product is a gel and not a cream. It seems to stay on better. I cannot recommend this product enough if you struggle with orofacial herpes (cold sores).

Glad I bought it! I didn’t get to buy it until after my cold sore started to blister but just a few minutes after the first application the pain and itching went away. The next day the swelling went down and they started to dry out! Highly recommend!!!

I was quite astonished that after three days, there was no point to applying the medicine any more, for the cold sore had disappeared!

Clera went to work right away at decreasing the stabbing pain at the nerve–ends. Within 3 full days—like magic—the blisters subsided and the pain vanished!

Just writing to tell you how much I love your product. I have tried everything under the sun when it comes to cold sore treatments and Clera by far surpasses the results of its competitors.
