Milia (singular: milium), commonly referred to as milk spots or oil seeds, are small, keratin-filled cysts that form when the eccrine sweat gland becomes clogged. These cysts are located just under the epidermis or on the roof of the mouth. While milia are most commonly associated with newborn babies, they can affect individuals of all ages. They typically appear around the nose and eyes and can also be found on the genitalia, where they are often mistakenly identified as warts or symptoms of a sexually transmitted disease. Additionally, milia may be confused with stubborn whiteheads due to their similar appearance.

Causes

Milia form due to the accumulation of keratin, a protein that is part of the skin's structure, leading to the blockage of sweat glands. Factors contributing to their development can include skin damage from sun exposure, blistering injuries, or long-term use of steroid creams.

Symptoms and Identification

Milia are characterized by small, dome-shaped bumps that are white or yellowish. They are typically painless and present no health risk but can be a cosmetic concern for some individuals. Unlike whiteheads, milia do not form in pores but rather in areas where the skin layers have become trapped.

Treatment and Management

While milia often resolve on their own, especially in infants, persistent cases may require treatment. Options include:

• Professional extraction by a dermatologist
• Topical retinoids
• Chemical peels
• Laser therapy

It is advised not to attempt to remove milia at home, as improper handling can lead to skin damage or infection.

Prevention

Preventive measures include avoiding excessive sun exposure, using non-comedogenic skincare products, and maintaining a regular skin care regimen to encourage healthy skin turnover.
