Cold Sore Gel For the relief of burning and itching

SOS Cold Sore Gel relieves burning and itching in cold sores on the lips and accelerates natural wound healing.

The active substance is silica gel (silicic acid gel), a combination of the mineral silicon with oxygen and water. Its special property is its unusually high binding capacity for water and secretions. The secretion from the cold sore blister is thus bound naturally, the blisters are specifically dried out and spread of the virus is reduced.

SOS Cold Sore Gel is clinically tested.


  • Specific drying of cold sore blisters
  • Prevents the virus from spreading
  • Accelerates natural wound healing
  • With natural silica gel
