Understanding and Treating Different Skin Lesions: Milia and Ductal Tumors
Every month, we address various skin health concerns, offering expert insights and practical tips. This time, we explore the common issue of lumpy lesions under the eyes, often mistaken for regular acne. Join us as dermatologist Dr. Lee Mi-hye sheds light on the differences between two similar-looking conditions: milia and ductal tumors.
The Similarities and Causes
Milia and ductal tumors are benign and usually asymptomatic. While both can develop on the face, especially around the eyes, they exhibit different histological features and require distinct treatments.
Milia can occur in both infants and adults and are filled with keratin in small pockets just below the skin’s surface. These lesions appear as tiny raised bumps containing white or yellowish material. The exact cause of milia is unknown, but it can be congenital or result from skin damage.
Ductal tumors, on the other hand, are inherited and often linked to abnormal sweat gland proliferation. These benign growths originate from the sweat ducts and tend to be deeper in the dermal layer compared to milia. Ductal tumors have a higher chance of recurring even after treatment.
Different Treatment Approaches
The choice of treatment depends on the size, depth, and distribution of the lesions. Milia can be removed through methods like direct destruction, extrusion using lasers (such as erbium or CO2), or needle extraction. It is important to consult a dermatologist to receive a proper diagnosis before attempting any treatment.
Ductal tumors can also be superficially destroyed through laser treatment or by using micro-needling techniques like Potenza 1pin or Agnes. These methods reduce damage to the skin surface, leading to faster healing and reduced scarring compared to traditional treatments. It’s worth noting that milia and ductal tumors can coexist, but the treatment approach remains the same.
Distinguishing Characteristics
While it’s easy to confuse milia and ductal tumors due to their similar appearance and location under the eyes, there are distinct visual cues to differentiate them. Ductal tumors tend to grow deeper in the skin and appear as multiple lesions around the eyes, cheeks, forehead, or philtrum. They blend in with the surrounding skin and are difficult to distinguish when removed.
Milia, on the other hand, occur shallower on the skin’s surface, presenting as white or yellowish ball-shaped keratin sacs. They maintain a clear boundary with the surrounding skin and are more common on the face, including the eyes and cheeks. While milia is easier to treat than ductal tumors, it often tends to recur.
Preventing Recurrence
Both ductal tumors and milia are relatively common and prone to recurrence, causing concern for many individuals. Prompt treatment can help prevent the growth of lesions, as leaving them untreated can result in an increase in number, spread, and fusion, making treatment more challenging. Therefore, re-treatment is often necessary.
Quick Tips to Prevent Milia:
- Avoid oily makeup if you have excessive sebum secretion.
- Apply moisturizer and sunscreen regularly for prevention.
- Avoid rubbing your eyes excessively or using high-function makeup for extended periods to prevent irritation.
- Seek treatment for any itching or dermatitis to minimize the risk of milia.
- Never attempt to squeeze milia at home, as it can lead to inflammation and scarring.
By understanding these common skin conditions, we can make informed decisions and seek appropriate care. Consult a dermatologist for proper diagnosis and treatment tailored to your specific needs.

In this series, we share skin health concerns that change every month. We provide clear answers and helpful tips for monthly skin diseases that everyone is curious about, with experts from the Color Dermatology Clinic.
An increasing number of people are experiencing stress due to the lumpy lesions under the eyes that started to become apparent at some point. Warts that appear around the eyes, which are a particularly visible part of the face, are easily mistaken for simple trouble, as papules similar to migratory acne appear around the eyes.
However, dermatological diseases with similar symptoms include ‘milia’ and ‘ductal tumour’. These similar symptoms may appear similar on the outside, but it is important to distinguish them because the course of the disease and the treatment are different. Let’s learn more about the differences between ductal tumors and milia with dermatologist Dr. Lee Mi-hye (Riwon Dermatology Clinic).

Q. What is the cause of milia and divine tumors?
Milia and ductomas are generally asymptomatic and relatively common benign lesions. It is common on the face, including around the eyes, and has the ability to create lesions that protrude from the surface of the skin, but there are differences in histological findings and treatment.
Although the cause is not clearly known, milia can occur on the skin of babies and adults, and the causes are known to be congenital effects or different damage to the skin. Milia are keratin-filled lesions in pockets just below the epidermis, which is the relative surface of the skin, and are visible to the naked eye as small, raised bumps that contain white or yellow bumps.
Hangwandoma is an inherited disease, so if someone in your family has Hangwandoma, you may develop hereditary Hangwandoma. An abnormal spread of sweat patches is suggested to be the main cause. A duct tumor is a type of benign tumor that occurs when the sweat ducts that secrete sweat proliferate. Because the lesion originates from the sweat gland duct, the lesion is located in the deeper dermal layer compared to milia and is more likely to recur even after treatment.
Q. What are the different treatments for milia and ductal tumors?
Clinical judgment is important depending on the depth, size and distribution of the lesion. In most cases, milia are removed by direct destruction or extrusion using an erbium or CO2 laser or a needle.
As keratinoma is not a skin disease that heals naturally, it is recommended to get a proper diagnosis by a dermatologist before symptoms worsen. Like milia, a method of destroying ductal tumors from the surface of the skin can be attempted using erbium or a CO2 laser. As the lesions are located deeper and have blurred borders compared to milia, microneedles such as Potenza 1pin or Agnes can be used. combining the method of removing lesions while reducing the damage to the skin surface using high frequency treatment, scarring and recovery time can be reduced compared to existing treatments, so satisfaction is high.
Milia and ductomas are relatively common benign lesions, and they often occur together. Even if they are mixed, the treatment does not change. Milia can be treated with milia, and milia can be treated with ductal tumors.
C. There are many cases where ductal tumors are mistaken for milia. What are the characteristics that distinguish the two diseases?
Because ductal tumors and milia are similar in appearance and size and occur mainly under the eyes, it is easy to confuse the two diseases. However, in typical cases, ductal tumors can be distinguished from milia visually.
Tumors grow deeper in the skin, and occur mainly around the eyes, cheeks, forehead, or philtrum, and have a multiple appearance. It has a color close to skin color and is not easily distinguishable from normal tissue when removed.
Milia occur shallowly on the surface of the skin and are white or yellow, ball-shaped keratin sacs that are well-bounded with the surrounding skin. It occurs mainly on the face, including around the eyes and cheeks, and is easier to treat than a vascular tumor, but as it is a common disease, it often comes back.
C. Hanwanoma is said to be a skin disease that is difficult to treat once it develops. What efforts are needed to prevent this from happening again?
Ductal tumors and milia are relatively common and often recur, causing concern for many people. In particular, ductal tumors are known to be difficult to treat because the lesions are deeper than milia and are not well separated from normal tissues. Prompt treatment can prevent lesions from developing, and if left untreated, lesions can increase in number, spread and fuse, making treatment more difficult. Re-treatment is usually recommended.
※ TIP Honey. Milia prevention method※
1. If you have excessive sebum secretion, do not apply oily makeup!
2. For prevention, apply moisturizer and sunscreen from time to time.
3. Avoid rubbing your eyes too much or using high function make-up for a long time as this can cause irritation.
4. Milia often appear when there is a skin disease, so if you have itching or dermatitis, get treatment right away.
5. If you try to squeeze too much at home, inflammation and scarring can occur. Never squeeze it by hand.
