Milia are small white or yellow bumps that appear on the skin. They are caused by a buildup of dead skin cells and oils in the skin’s pores. While primary milia form on their own, secondary milia can be caused by a variety of factors, including skin damage, certain medications, and medical conditions. This article will explore what causes secondary milia and how to treat them.Secondary Milia are small, white cysts that can form when a primary milium (single milia) becomes infected or irritated. They are typically found in the area around the eyes, nose and mouth. Secondary Milia are caused by an accumulation of dead skin cells that become trapped beneath the surface of the skin. They can be painful and itchy, and may require treatment with antibiotics or topical creams to reduce their size and discomfort.
Types of Milia
Milia are small, white bumps that typically appear on the skin. They are caused when keratin, a protein found in the skin, becomes trapped under the surface of the skin. Milia can occur in any area of the body but are most commonly found on the face, particularly around the eyes and cheeks. There are several different types of milia, each with its own characteristics and treatment options.
Primary Milia
Primary milia is the most common type of milia and usually affects newborns or young children. It is caused by clogged pores and usually goes away without any treatment within a few weeks or months.
Secondary Milia
Secondary milia is less common than primary milia and typically affects adults over the age of 40. It is caused by damage to the skin from excessive sun exposure, cosmetic treatments such as chemical peels or laser treatments, or medications such as certain acne medications or steroids. Secondary milia may require professional treatment in order to be resolved.
Retentional Milia
Retentional milia occurs when a pore becomes blocked with sebum (a type of oil produced by the skin). This can happen when there is an overproduction of sebum due to genetics, hormones, or other conditions such as eczema or psoriasis. Retentional milia can be difficult to treat and may require professional intervention in order to resolve it.
Traumatic Milia
Traumatic milia is caused by physical trauma to the skin such as burns, cuts, scrapes or other injuries that cause scarring. These types of milia typically resolve on their own without any medical intervention but may take time to heal completely depending on how severe they are.
What Causes Primary Milia?
Primary milia is a common skin condition that occurs when dead skin cells become trapped beneath the surface of the skin. It usually occurs in infants, but it can also occur in adults. Commonly found on the face, chest and back, primary milia appears as small, white bumps that are often surrounded by redness. While it is usually harmless and does not require any treatment, understanding what causes primary milia can help you better manage the condition.
The exact cause of primary milia is unknown, but it is thought to be related to a buildup of keratin within the skin’s pores. Keratin is a protein that helps keep your skin healthy and strong. When too much keratin builds up in the pores, it creates a blockage which traps dead skin cells beneath the surface of the skin. This leads to the formation of small white bumps known as primary milia.
In addition to an excess buildup of keratin, there are several other factors that may contribute to primary milia including dry skin, overexposure to sunlight and certain medications or treatments such as topical retinoids or steroid creams. People with certain genetic disorders such as epidermolysis bullosa may also be more likely to develop primary milia due to their fragile skin structure.
What Causes Secondary Milia?
Secondary milia is caused by trauma to the skin, often through injury or aggressive exfoliation. It can also be caused by exposure to harsh chemicals, such as those found in some acne medications. In some cases, secondary milia can be caused by an underlying medical condition such as epidermolysis bullosa or pemphigus vulgaris. In rare cases, secondary milia can be caused by the use of certain medications that cause prolonged irritation of the skin. Finally, it can be caused by overexposure to sunlight or other forms of ultraviolet radiation.
In most cases, secondary milia is a benign condition that does not require treatment. However, if it is causing discomfort or embarrassment, there are several treatments available. These include topical retinoids, chemical peels, laser treatments and microdermabrasion. Your doctor will be able to advise on which treatment would work best for you and your individual needs.
Secondary Milia in Infants
Secondary milia is a common skin condition in infants that causes white bumps to appear on the skin. These bumps are not contagious, but can be unsightly and bothersome. Secondary milia occur when a blocked sweat gland or hair follicle becomes enlarged and filled with the proteins that form keratin. These proteins then become trapped beneath the surface of the skin, causing the white bumps to appear. While secondary milia is more common in infants, it can also occur in adults as well.
The good news is that secondary milia typically resolves on its own without any special treatment. The condition usually disappears within a few weeks or months without any medical intervention. It’s important to keep the affected area clean and dry to prevent any infection from developing, but other than that there is no need for treatment.
If secondary milia persists for more than a few months or if it appears in an unusual location, it may be necessary to have it checked out by a doctor or dermatologist. In some cases, steroid creams may be prescribed to reduce inflammation and help resolve the condition faster. However, these should only be used under medical supervision as they can cause side effects if used incorrectly.
In Last Thoughts, secondary milia is a relatively common skin condition in infants that typically resolves itself without any special treatment or medication. However, if it persists for an extended period of time or appears in an unusual location it’s important to have it checked out by a healthcare professional so that any underlying causes can be identified and treated appropriately.

Is Secondary Milia Treatable?
Secondary milia is a condition that is characterized by the presence of small, white bumps on the skin. It can occur in both adults and children. While primary milia is harmless and does not require treatment, secondary milia may be caused by an underlying medical condition and should be evaluated by a dermatologist. In some cases, secondary milia is treatable depending on the underlying cause.
Treatment for secondary milia can involve topical creams or ointments, chemical peels, laser treatments, or cryotherapy (freezing). Treatment options vary depending on the cause and severity of the condition. For example, if the milia are caused by an infection, your doctor may prescribe antibiotics. If they are caused by a skin disorder such as psoriasis or eczema, your doctor may recommend topical steroids or other medications to reduce inflammation.
In some cases where the underlying cause cannot be determined or is not treatable, it may be necessary to remove the affected area surgically. This is usually done with a local anesthetic and can help improve the appearance of the skin. However, it is important to note that surgical removal of milia does not always result in permanent improvement and may require further treatments such as laser resurfacing or chemical peels to achieve desired results.
Overall, secondary milia can be treated depending on the underlying cause. It is important to see a dermatologist if you have any concerns about your skin so that they can determine an appropriate treatment plan for you.
Are There Any Home Remedies for Secondary Milia?
Secondary milia is a skin condition that can cause hard, white bumps to appear on the skin. These bumps may be itchy or uncomfortable, and can be difficult to remove. While there are certain treatments available from a dermatologist, such as chemical peels or laser treatments, some people prefer to try home remedies first.
Fortunately, there are several home remedies that may help reduce the appearance of secondary milia. One of the most common is using a warm compress. Applying a warm compress to the affected area for 10-15 minutes several times a day can help open up the pores and reduce inflammation. It can also help soften the bumps and encourage them to heal faster.
Exfoliation is another option for treating secondary milia at home. Using an exfoliating scrub or brush can help remove dead skin cells, which may reduce inflammation and make it easier for the sebum in the pores to escape. It’s important to use gentle exfoliators that won’t irritate the skin, such as ones containing natural ingredients like oatmeal or baking soda.
In addition to exfoliation and warm compresses, over-the-counter topical creams may also be beneficial in treating secondary milia. Look for products that contain retinoids or alpha hydroxy acids (AHAs), which can help reduce inflammation and encourage cell turnover. However, it’s important to read labels carefully and avoid any products that contain fragrances or other harsh ingredients that could irritate your skin further.
It’s also a good idea to keep your skin hydrated by using moisturizers regularly, particularly after exfoliating or using topical creams. This can help keep your skin healthy and prevent dryness or irritation from occurring in the future. Additionally, make sure you wear sunscreen every day when you go outside—this will protect your skin from ultraviolet rays and reduce your risk of developing secondary milia in the future.
Overall, while secondary milia can be difficult to treat at home, there are several home remedies that may provide some relief from this condition. From warm compresses and exfoliation to over-the-counter topical creams and moisturizers, there are many options available for those looking for more natural ways to manage their symptoms of secondary milia.
Sun Exposure Linked to Secondary Milia
Milia, or tiny white bumps, are commonly found on the skin. They are typically harmless and can occur in both adults and children. While primary milia is caused by blocked oil glands, secondary milia is often the result of sun exposure. Sun-damaged skin can form a hard layer over the skin, trapping dead cells and oils within the pores. This can lead to milia formation.
People who spend a lot of time in the sun are more likely to develop secondary milia. In addition, people with lighter skin tones may be at higher risk due to their inability to tan. Those who use tanning beds may also be more prone to forming secondary milia due to their increased exposure to UV rays.
To reduce your risk for secondary milia, you should take measures to protect your skin from too much sun exposure. Wear sunscreen with an SPF of at least 30 when outdoors for extended periods of time and avoid direct sunlight during peak hours (10am-4pm). Additionally, wear protective clothing such as long sleeves and pants when possible. These strategies will help you reduce your risk for developing secondary milia due to sun exposure.
