Yes, milia are essentially small cysts filled with dead skin cells (keratin) trapped beneath the surface of the skin.
Milia are those small, white or yellowish bumps that commonly appear on the face, especially around the eyes, nose, and cheeks. While they might resemble whiteheads, they're formed differently.
Here's a more detailed breakdown:
- What are Milia? Milia are tiny, benign cysts that appear as raised, pearly-white or yellowish bumps on the skin.
- The Role of Keratin: Keratin is a protein found in skin, hair, and nails. In the case of milia, dead skin cells containing keratin become trapped beneath the skin's surface.
- Cyst Formation: When these dead skin cells don't shed properly, they become encased in a cyst-like structure.
- Distinction from Acne: Unlike acne, milia aren't associated with inflammation or bacteria. They are simply trapped keratin.
- Why it Happens: Causes can include skin damage from sun exposure, blistering injuries, or the use of heavy creams and oils. Sometimes, milia appear spontaneously without a clear cause.
- Treatment: Milia usually disappear on their own, but you can consult a dermatologist for extraction or topical retinoid treatments to speed up the process. Avoid squeezing them as this can damage the skin.
In summary, milia are indeed related to dead skin, as they are formed when dead skin cells (keratin) become trapped under the skin and form small, harmless cysts.
