What is a small cluster of small clear bumps forearm?

A small cluster of clear bumps on the forearm could be caused by several conditions, such as folliculitis, which is inflammation of hair follicles, or a condition called keratosis pilaris, characterized by tiny, rough bumps. Allergic reactions or irritations, such as contact dermatitis, may also present as clear bumps. If the bumps persist, change, or are accompanied by other symptoms, it's advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
