3. Poison Ivy
Poison ivy is a plant that releases oils that can cause irritation to the skin. If the oils get on the skin or into the bloodstream, a person who has an allergy to the oils can develop a skin rash. Poison ivy can be serious and it can easily spread to other areas of the body. If it gets in the eyes or if it infects the bloodstream, it can be very serious. Some people are more allergic to poison ivy than others and some have no reactions at all.
Since poison ivy affects the skin, it can cause milia to appear as well. In some cases, the milia can appear at the same time as the irritation caused by the poison and it can be mistaken for the poison. Poison ivy usually itches why milia don’t cause pain or itchiness. Once the poison ivy has dried up and is no longer a problem, the milia may go away.
