Hi there,
I can confirm the exact cause of your son’s symptoms only after a clinical examination. It could be some allergy, inflammation or infection. The common possibility is that it is contact dermatitis which may occur after allergy to any soap, deodarants, food or medication. There are red rashes with itching in this condition. You may try giving him an over the counter antihistaminic like hydroxyzine.Topical application of calamine lotion may provide relief in itching. A clinical examination by  a Paediatrician/dermatologist may confirm the diagnosis.
Best wishes and regards!

Acne is not dangerous, but can leave skin scars. Human skin has pores (tiny holes) which connect to oil glands located under the skin. The glands are connected to the pores via follicles - small canals. These glands produce Sebum, an oily liquid. The sebum carries dead skin cells through the follicles to the surface of the skin.
