Belgian skincare manufacturer Sylphar has launched its mouth ulcer and cold sore treatments in Boots stores.

Herpatch Mouth Ulcer Gel and Herpatch Cold Sore Prevention Sticks have both been available to buy in Boots stores nationwide from last month, Sylphar said.

The gel, which contains hyaluronic acid, zinc and aloe vera, creates an “adhesive physical barrier” over ulcers to stop irritants entering the infected tissue, it said. The alcohol-free product was suitable for adults, children and pregnant women and came in a “handy pump dispenser”, the manufacturer said.

The cold sore balm was a “pioneering” moisturising treatment that blocked “triggers” that could lead to a cold sore blister, such as sunlight, Sylphar said. Sylphar said it planned to launch the treatments in other pharmacies in the future, but had not set a date.

Herpatch Mouth Ulcer Gel retails at £7.00 and the Cold Sore Prevention Stick at £4.99.
