What are Milia? Causes, Symptoms, and Treatment Options

Milia are small, benign growths that can appear on the skin, often in areas where there has been previous trauma or inflammation. They are usually white or yellowish in color and have a rough, sandpapery texture. Milia are not the same as moles, and they do not grow in the same way.
Milia are caused by the retention of keratin, a protein that is normally present in skin cells. When skin cells die and fall off, they leave behind a small amount of keratin that can accumulate and form a milium. This can happen for a variety of reasons, including:

* Trauma to the skin, such as a cut or burn
* Inflammation, such as acne or eczema
* Genetic predisposition
* Hormonal changes, such as those that occur during puberty or pregnancy

Milia are usually harmless and do not cause any symptoms. However, they can become inflamed or infected, which can lead to redness, swelling, and pain. In rare cases, milia can become cancerous, so it is important to have them checked by a dermatologist if they change in size, shape, or color, or if they become inflamed or infected.

Treatment for milia usually involves draining the contents of the milium and removing the keratin that has accumulated. This can be done using a small needle or by applying a topical treatment to help loosen the keratin. In some cases, multiple treatments may be necessary to completely remove the milium. It is important to avoid picking or squeezing milia, as this can cause further inflammation and scarring.

Preventing milia is not always possible, but there are some steps you can take to reduce your risk of developing them. These include:

* Avoiding trauma to the skin
* Keeping the skin clean and moisturized
* Avoiding harsh soaps and cleansers
* Protecting the skin from the sun
* Avoiding tight clothing that can cause friction and irritation

If you notice a milium on your skin, it is important to see a dermatologist for proper diagnosis and treatment. They will be able to determine if the growth is a milium or something else, and they will be able to recommend the best course of treatment.
