Yes, cut it off. But the tissue under the stretched skin is still tender, so it should be protected to prevent scratches and infections. I recommend a pure Chinese medicine ointment, Bai Chuang Hao, which is an old prescription that lasts for thousands of years. Their children's special type can protect children's scalded parts, prevent dryness, repair tissues, breed new skin, prevent infection and reduce the chance of leaving scars. But also has no irritation and side effects. You can search for Bobbie Baichuang on Taobao to find the manufacturer.
