Final answer:
Milia are small, white cysts that form on the skin. They are caused by the buildup of keratin and are typically harmless. Treatment options may be recommended if they cause discomfort or affect one's appearance.
Step-by-step explanation:
Milia are small, white cysts that form on the skin. They are caused by the buildup of keratin, a protein that helps protect and strengthen the skin. Milia are commonly seen in newborns but can also occur in teenagers and adults.
Milia are typically harmless and do not require treatment. However, if they cause discomfort or affect one's appearance, a dermatologist may recommend treatment options such as piercing the cyst with a sterile needle or using topical retinoids to promote exfoliation.
It is important to note that milia should not be confused with other skin conditions such as acne or skin cancer. If you have concerns about any skin abnormality, it is always best to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
