"Piece of skin with bumps on the edge of the finger?"

It is possible that the skin irritation on the edge of your finger could be caused by contact with an irritant such as detergent, cleaning product, or nail glue. I recommend avoiding potential irritants and using a fragrance-free moisturizing cream regularly. You may also want to wear gloves when handling cleaning products or doing dishes, and apply sunscreen to your hands when going outside. Try these recommendations for 7 to 10 days and assess the situation afterward. If you have any further questions, feel free to reach out to a pharmacist or healthcare professional.
