What is milia?

Milia are small, raised bumps that typically appear on the face, but can also occur on other areas of the body. These bumps are filled with keratin, a protein found in the outer layer of the skin. Milia can range in size from as small as a pinhead to as large as a pea, and they have a pearly or white appearance.

Milia occur when dead skin cells become trapped beneath the surface of the skin, forming small cysts. These cysts are usually harmless and painless, but they can be frustrating to deal with, especially if they appear in noticeable areas like the face.

Understanding Milia

Milia are typically small, dome-shaped bumps that commonly appear on the face, around the eyes, cheeks, and nose. They can also occur on other parts of the body. Unlike acne, milia don’t develop from blocked pores. Instead, they form when dead skin cells become trapped beneath the skin’s surface, leading to tiny cysts. 

There are two main types of milia:

1. Primary Milia:

These are common in infants and often disappear on their own within a few weeks. They occur when skin cells do not properly exfoliate and shed.

2. Secondary Milia:

These can develop at any age due to damage to the skin, such as burns, sun damage, or as a side effect of certain medications.

Causes of milia

There are several factors that can contribute to the formation of milia. One common cause is sun damage. Overexposure to the sun’s harmful UV rays can damage the skin and lead to the development of milia. Additionally, certain skin care products, such as heavy creams or oils, can clog the pores and contribute to the formation of milia.

Genetic factors can also play a role in the development of milia. Some individuals may be more prone to developing multiple milia, due to their genetic makeup. Hormonal changes, such as those that occur during pregnancy, can also trigger the formation of milia.

Different types of milia

There are several different types of milia, each with its own unique characteristics. The most common type is known as primary milia, which occurs in individuals of all ages. Primary milia typically appears on the face, especially around the eyes, cheeks, and nose.

Secondary milia, on the other hand, is associated with certain underlying skin conditions or trauma to the skin. This type of milia can develop as a result of burns, blisters, or prolonged use of topical corticosteroids.

Neonatal milia is another type baby acne that affects newborns. These milia often appear on the baby’s face, particularly on the nose and cheeks. Neonatal milia typically resolves on its own within a few weeks or months.

Who is more prone to getting milia?

While milia can affect individuals of all ages, certain factors may make some individuals more prone to developing this skin condition. Newborns are particularly susceptible to milia, as their sweat glands are not fully developed. In adults, milia are more common in individuals with certain skin types, such as those with dry or dehydrated skin.

Individuals who have a history of sun damage or frequent exposure to the sun’s harmful UV rays are also more likely to develop milia. Additionally, individuals who use heavy skin care products or have a family history of milia may be more prone to developing this condition.

Treatment options for milia

The good news is that milia can be effectively treated. The treatment options for milia vary depending on the severity and location of the bumps. In some cases, milia may resolve on their own without any intervention. However, if the milia persist or become bothersome, there are several treatment options available.

Another treatment option is the use of topical creams or ointments containing ingredients like retinol or alpha hydroxy acids. These ingredients can help to exfoliate the skin and promote the shedding of dead skin cells, reducing the appearance of milia.

In some cases, professional extraction may be necessary to remove stubborn milia. This procedure is typically performed by a dermatologist or esthetician using a sterile needle or blade to carefully extract the milia. It’s important to note that extraction should only be performed by a trained professional to avoid any potential complications.
