Cymex cream

How does it work?

Cymex cream contains four active ingredients; urea, dimeticone, cetrimide and chlorocresol.

Urea is a moisturiser that works by penetrating into the lips, where it attracts and retains water. Urea also breaks down keratin in the skin cells, helping them to shed, which softens and improves the appearance of dry, cracked lips. This action also improves the ability of moisturising ingredients to penetrate the lips and rehydrate them.

Dimeticone acts as a water repellant to help protect the lips.

Cetrimide and chlorocresol are mild disinfectants that help control infection.

The cream also contains liquid paraffin and cetostearyl alcohol, which are moisturising agents that prevent water evaporating from the lips.

These ingredients provide a triple action that helps relieve cold sores and painful dry cracked lips.

The cream should be applied every hour until the cold sore fades.
