What could cause tiny bumps on my lips to feel like sandpaper?

When your lips have little bumps that feel like sandpaper, it might be a type of cheilitis, which means the skin of your lips is irritated or inflamed. This irritation can happen for a few reasons. For example, constant licking, picking, or rubbing of the lips can lead to a condition called lichen simplex chronicus. Also, exposure to irritants or even too much sun can change the skin on your lips, sometimes making it rough or scaly. In some cases, it might appear as tiny keratotic (thickened) bumps. This is similar to what happens in some people who have other skin conditions, and sometimes even in organ-transplant recipients more susceptible to skin problems. Exfoliative cheilitis is one such form where the skin peels and may feel rough. If you notice these changes on your lips, it might help to avoid behaviors or substances that irritate your lips, use a gentle lip balm, and protect them from the sun.
