Milia, often referred to as "milk spots," are typically painless and usually do not cause itching or discomfort. They can be categorized into primary, secondary, or multiple types, depending on the underlying cause. Primary milia are formed directly from entrapped keratin, while secondary milia can occur as a result of injury to the skin, such as burns or rashes. Multiple milia can develop in large numbers, making them more noticeable.
It's important to note that attempting to remove milia at home can lead to scarring or infection. Consulting a dermatologist for professional extraction is the safest approach. Prevention strategies include using non-comedogenic skincare products and avoiding heavy creams or oils, especially in areas prone to milia formation.
