Hi Dear, Welcome to HCM. Understanding your concern. As per your query your son have bumps under eye is mainly allergic contact dermatitis. It could be due to infection of skin and hair follicles as they can also cause similar bumps. I would suggest you to visit dermatologist once as clinical assessment of the bumps is necessary for diagnosis. You can consult with paediatrician as well. Till then You can use topical mild steroid cream like hydrocortisone creams. You can give child antihistamine orally. Give him plenty of water to drink. Wipe the area under eyes with wet tissues as well. Give him diet rich in multivitamins. You can try with topical eye antibiotics as well and avoid all type of cosmetics around eye of child. Hope your concern has been resolved. Get Well Soon. Best wishes, Dr. Harry Maheshwari
