While they are harmless, they can sometimes cause concern due to their appearance. Milia are often mistaken for acne or other skin conditions, but they are distinct in their formation and treatment. Understanding what milia are, why they occur, and how to manage them can help you take better care of your skin. This article dives deep into the topic of milia, providing you with valuable insights and practical advice.
Milia are small, keratin-filled cysts that form when dead skin cells become trapped beneath the surface of the skin. Unlike acne, milia are not caused by clogged pores or bacteria, which is why typical acne treatments often fail to address them. They are most commonly found on the face but can appear on other parts of the body as well. While milia are more prevalent in newborns, adults can also develop them, especially if they have certain skin types or conditions. Learning about milia can empower you to make informed decisions about your skincare routine and seek appropriate treatments if necessary.
Many people wonder why milia occur and whether they can prevent them. Factors such as sun damage, harsh skincare products, and certain medical conditions can contribute to their development. However, milia are not always preventable, and they may resolve on their own over time. For those who wish to speed up the process or address persistent milia, professional treatments and at-home remedies can be effective. Keep reading to explore everything you need to know about what is milia, including its causes, symptoms, and solutions.

What Is Milia?
Milia are small, dome-shaped bumps that appear on the skin due to trapped keratin. Keratin is a protein that helps protect the skin and is also found in hair and nails. When dead skin cells and keratin become trapped beneath the skin's surface, they form tiny cysts. These cysts are usually white or yellowish and have a smooth texture. Milia are most commonly found on the face, particularly around the eyes, cheeks, and forehead, but they can also appear on other parts of the body.
While milia are often associated with newborns, they can occur at any age. In infants, milia are typically referred to as "baby acne," although they are not related to hormonal changes like true acne. For adults, milia are often linked to sun damage, improper exfoliation, or the use of heavy skincare products. Understanding the nature of milia is the first step in addressing them effectively.
What Causes Milia?
Several factors can contribute to the development of milia. One of the primary causes is the accumulation of dead skin cells and keratin beneath the skin's surface. This can happen due to insufficient exfoliation, which prevents the skin from shedding old cells properly. Additionally, certain skincare products, especially those that are too thick or occlusive, can trap debris in the pores, leading to milia.
Another common cause of milia is sun damage. Prolonged exposure to UV rays can thicken the skin's outer layer, making it harder for dead skin cells to slough off naturally. This increases the likelihood of milia formation. Medical conditions such as blistering disorders, burns, or even certain medications can also trigger milia in some individuals.
Can Milia Be Prevented?
While it may not always be possible to prevent milia, adopting a proper skincare routine can significantly reduce the risk. Regular exfoliation is key to removing dead skin cells before they can become trapped. However, it’s important to avoid over-exfoliating, as this can irritate the skin and worsen the condition. Gentle chemical exfoliants like alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs) are often more effective than physical scrubs.
Using lightweight, non-comedogenic skincare products can also help prevent milia. These products are formulated to avoid clogging pores, making them a better choice for individuals prone to milia. Protecting your skin from sun damage by wearing sunscreen daily is another essential step in prevention.

How to Identify Milia?
Milia are often mistaken for other skin conditions, such as whiteheads or acne. However, there are key differences that can help you identify them. Unlike acne, milia are not inflamed or red, and they do not contain pus. They are typically small, firm, and white or yellowish in color. Milia are also painless and do not respond to typical acne treatments.
Another distinguishing feature of milia is their location. They are most commonly found on the face, particularly around the eyes and cheeks. In some cases, milia can appear on the eyelids or even the genital area. If you are unsure whether you have milia, it’s best to consult a dermatologist for a proper diagnosis.
What Is Milia in Children?
Milia are extremely common in newborns and are often referred to as "milk spots." These tiny white bumps usually appear on the nose, cheeks, and chin and are completely harmless. In most cases, milia in infants resolve on their own within a few weeks or months without any treatment. It’s important not to squeeze or attempt to remove milia in babies, as this can cause irritation or infection.
How to Treat Milia?
Treating milia depends on their severity and persistence. In many cases, milia will disappear on their own without intervention. However, if they are bothersome or persistent, there are several treatment options available. Professional treatments, such as extraction or laser therapy, are often the most effective methods for removing milia. These procedures should only be performed by a licensed dermatologist to avoid complications.
Professional Treatments for Milia
Professional treatments for milia include manual extraction, laser therapy, and chemical peels. During manual extraction, a dermatologist uses a sterile needle or blade to gently remove the contents of the cyst. Laser therapy targets the milia with focused light energy, breaking them down without damaging the surrounding skin. Chemical peels involve applying a solution to the skin to exfoliate the top layer, which can help reduce milia over time.
Home Remedies for Milia
If you prefer to address milia at home, there are several remedies you can try. Regular exfoliation with gentle products can help prevent milia from forming. Incorporating ingredients like salicylic acid or glycolic acid into your routine can also be beneficial. Additionally, steaming your face can help open up pores and loosen trapped debris, making it easier for milia to resolve naturally.
Common Misconceptions About Milia
There are several misconceptions about what is milia that can lead to ineffective treatments. One common myth is that milia are a type of acne. While they may look similar, milia and acne have different causes and require different approaches to treatment. Another misconception is that squeezing milia will make them go away. In reality, attempting to remove milia at home can lead to scarring or infection.
