Brand
Mederma
Mederma is a scar-care brand built around Cepalin, a proprietary onion bulb extract. It was developed by Merz Pharmaceuticals and grew into one of the most pharmacist-recommended over-the-counter scar brands. The global rights moved to HRA Pharma, which Perrigo acquired in 2022, so Mederma now sits in Perrigo's self-care portfolio.
