Had to go to Pharmacist to check on one of those skin tears we’re prone to. She was so horrified at the bruising as I took off the dressing that she used this magical medical adhesive remover. Lift Plus Medical Adhesive Remover (Ref 5503). Input in your search engine and you’ll find several suppliers.
Then she gave me the rest very kindly! It absolutely works. You spray it along the edges of the dressing and gently pull back BUT it doesn’t tug or stretch, just gently glides off. Wonderful!
