How does one know if they injured the dermal layer of the nose skin?

If someone had a scrape on their nose, how would they know if they injured only the epidermis vs the dermal layer? Are the layers different in texture? The scrape has not healed in one year, but there was no blood for it to be a scar. Would the nose skin need more time to thicken?
