"What could I apply for dry skin on my finger?"

For dry skin on your finger, you could try using a thicker moisturizer like Cetaphil or even vaseline, applying it at least three times a day and after washing your hands or using hand sanitizer. It is also important to wear gloves when doing household chores like laundry or washing dishes to protect your skin. Additionally, don't forget the effects of the sun - make sure to apply sunscreen at least 30 minutes before going outside.
