Milia is a skin condition that can cause small, raised, white or yellow bumps to form on the skin. It is usually found on the face and is more common in infants, but can affect adults as well. Milia can be divided into two main categories – primary milia and secondary milia. Primary milia is caused by a blockage of the sweat glands and occurs when dead skin cells become trapped in a pocket of keratin under the surface of the skin. Secondary milia is caused by damage to the epidermis (outer layer of skin) and usually occurs after trauma or certain medical treatments such as laser resurfacing or chemical peels. While both types of milia are usually harmless, it can be important to distinguish between them in order to determine the best course of treatment.Primary Milia is a type of skin condition that is characterized by the appearance of multiple, small, white bumps on the skin. These bumps are typically dome-shaped and can appear on any part of the body but are most commonly found on the face, especially around the eyes and cheeks. Primary Milia is caused by an accumulation of keratin which becomes trapped beneath the surface of the skin. It does not usually require treatment however it can be removed with a variety of treatments including dermabrasion or cryotherapy.
Secondary Milia
Secondary milia are small, cyst-like bumps that appear on the skin. They are caused by a build-up of keratin beneath the surface of the skin. Keratin is a protein found in the outermost layer of skin, and it can form cysts when it accumulates in large amounts. Secondary milia can appear anywhere on the body but are most commonly seen on the face and neck. They usually range in size from 1 to 4 millimeters and may be yellowish or white in color. Secondary milia may be accompanied by itching or irritation, though this is not always the case.
These bumps can occur as a result of a variety of causes, including sun exposure, certain medications, topical skin care products, injuries to the skin, and genetic disorders. In some cases, secondary milia may resolve on their own after a few weeks or months; however, they can sometimes linger for years if left untreated. Treatment options vary depending on the underlying cause of the cysts but may include topical retinoids or other medications to reduce inflammation and reduce keratin production. In more severe cases, surgical removal may be necessary.
It is important to note that secondary milia should not be confused with primary milia, which are typically seen in newborns and infants as small white bumps on their faces and bodies. Primary milia do not require treatment since they will usually resolve on their own within a few weeks or months.
Primary Milia
Primary milia are a common skin condition that is characterized by small, white bumps on the skin. The bumps are typically found on the face, especially around the cheeks and nose, but can also appear on other parts of the body. Primary milia are benign (noncancerous) and usually resolve on their own without any treatment. However, they can be unsightly and may require medical intervention in some cases.
Causes of Primary Milia
Primary milia can be caused by a variety of factors, including genetics, sun damage, medications, and skin injury. Genetics may play a role in some cases as certain gene mutations have been linked to primary milia. Sun damage from prolonged exposure to ultraviolet (UV) rays is another potential cause of primary milia as UV radiation can damage the skin’s outer layers and lead to clogged pores. Certain medications such as topical steroids may also contribute to primary milia as they can cause an overproduction of keratin which then gets trapped in the pores. Lastly, skin injuries such as burns and other trauma can result in primary milia due to blocked pores caused by scar tissue or dead cells.
Symptoms of Primary Milia
Milia are small, white bumps that can appear on the skin. They are caused by blocked oil glands or dead skin cells. Primary milia are common in newborns and adults, and can occur anywhere on the body. The most common symptom of primary milia is the appearance of small, white bumps on the skin. These bumps are usually 1-2 millimeters in diameter and can be found on the face, chest, arms, or back. They may also appear around the eyes, nose, and mouth. Other symptoms may include redness or itching around the affected areas. In some cases, primary milia may be mistaken for acne due to their similar appearance.
In newborns, primary milia often occur in clusters and can be found all over the body. In adults, they are more likely to appear as single bumps on areas that have been exposed to sun damage or other forms of skin trauma. It is important to note that primary milia is a benign condition and does not cause any health risks or complications. Treatment is typically not necessary but may be recommended if the condition is causing discomfort or embarrassment.
Treatment for Primary Milia
Milia are small, white bumps that can appear on the skin at any age. While milia are harmless and often require no treatment, some people may want to remove them for cosmetic reasons. Treating primary milia can be done in a variety of ways, including topical creams, lancing and extraction, and laser procedures. It’s important to consult a dermatologist before attempting any treatment.
Topical creams are typically used to soften the outer layer of skin surrounding the milia. This allows them to be easily removed with a comedone extractor or needle lancing. These procedures involve gently puncturing the skin and squeezing out the contents of the bump. This method is generally considered safe for most adults. However, it should not be performed on children or people with sensitive skin.
Laser treatments may also be used to treat primary milia. Lasers use pulses of light energy to target and reduce the size of the bumps. This type of treatment is usually done in a doctor’s office and may require several sessions for best results.
In some cases, primary milia can be difficult to treat with topical creams or laser treatments. In these instances, surgery may be necessary to remove the bumps completely. Surgery involves making an incision in the skin and then extracting the contents of each bump individually with forceps or another surgical tool.
No matter which treatment is chosen for primary milia, it’s important to follow all instructions provided by a dermatologist in order to ensure proper healing and avoid further complications. Additionally, it’s important to keep in mind that while most treatments are effective at removing milia from the surface of the skin, they do not address any underlying cause that may have led to their formation in the first place.
Causes of Secondary Milia
Milia are small cysts that form when keratin becomes trapped beneath the skin’s surface. It is very common in newborns and can also occur in adults due to various causes. Secondary milia are caused by underlying conditions or treatments, such as skin injuries, severe burns, long-term use of topical steroids, and certain skin disorders.
Injury to the skin can damage the keratin-producing cells that are typically found in the epidermis. This can disrupt the normal process of keratin production and cause it to become trapped beneath the surface of the skin, forming milia. Severe burns can cause a large number of milia to form on the affected area of skin because of the extensive damage to the epidermis.
The use of topical steroids over a long period of time can also lead to secondary milia. These medications contain corticosteroids which reduce inflammation and suppress the immune system. When used for an extended period or at a higher strength than recommended, they can interfere with normal keratin production and cause milia to form.
Certain skin disorders can also lead to secondary milia. For example, patients with epidermolysis bullosa (EB) have an increased risk for developing milia due to their fragile skin which is prone to blistering and scarring from even minor trauma or infection. In addition, people with pemphigus vulgaris or porphyria cutanea tarda may develop secondary milia due to their respective conditions affecting epidermal cell division and keratin production within their bodies.

Symptoms of Secondary Milia
Secondary milia may appear as small, whitish bumps on the skin. These bumps are generally the size of a pinhead and may be found in clusters. They are usually found on the face, around the eyes, lips, and nose. Other areas of the body where secondary milia can occur include the chest, arms, and hands. The bumps can be itchy or tender but are usually painless. In some cases, they may become inflamed or irritated due to sun exposure or other environmental factors. Secondary milia can also cause discoloration of the skin around them, especially if they become inflamed or irritated.
The symptoms of secondary milia are more apparent in people with lighter skin tones due to its whitish coloration being more visible against lighter skin tones. People with darker skin tones may experience discoloration rather than a bumpy appearance as a symptom of secondary milia.
Treatment for Secondary Milia
Secondary milia can usually be managed with one or more of the following treatments: topical retinoids, salicylic acid, alpha hydroxy acid, glycolic acid, lactic acid, and photodynamic therapy. Topical retinoids are a type of vitamin A-based medication which helps to reduce the appearance of milia by exfoliating the skin and sloughing off dead skin cells. Salicylic acid is a beta hydroxy acid that helps to dissolve excess sebum and unclog pores. Alpha hydroxy acids such as glycolic and lactic acids help to remove dead skin cells by gently exfoliating the surface of the skin. Photodynamic therapy is a light-based treatment used to target blemishes and reduce inflammation.
In some cases, primary milia may require more aggressive treatments such as dermabrasion or laser resurfacing. Dermabrasion involves using an exfoliating brush or diamond tip to physically remove the top layers of skin while laser resurfacing is used to target specific areas with high levels of milia. Both techniques can be effective at reducing the appearance of milia but may cause some discomfort and temporary redness or swelling post-treatment.
If you’re looking for a more natural approach to treating secondary milia, there are several home remedies that may help reduce the appearance of these small white bumps. These include using products containing tea tree oil, coconut oil, aloe vera gel or honey as well as exfoliating regularly with gentle scrubs or fruit enzyme masks.
Conclusion
Primary milia and secondary milia are two different types of skin condition. Primary milia is caused by an accumulation of keratin under the skin, and is typically harmless and resolves on its own. Secondary milia is associated with other skin conditions, such as acne, and can be caused by damage to the skin. Treatment for secondary milia may require medical intervention.
It is important to distinguish between primary and secondary milia in order to determine the best treatment option for each individual case. If you suspect you are suffering from either type of milia, it is important to speak with a qualified dermatologist who can provide a diagnosis and recommend an appropriate treatment plan.
Overall, primary and secondary milia are two very different conditions that require different management plans in order to achieve the best results. It is important to be aware of the differences between them so that you can get the most effective treatment for your individual needs.
