The occurrence of these bumps is due to the trapping of keratin under the skin's surface. Keratin is a protein abundant in our hair, nails and skin tissue. Milia may develop in people of all ages and ethnicities, and are a common occurrence in newborns and infants.
Milia may occur anywhere on the body but are most commonly seen on the face, particularly the cheeks, lips and eyelids. Milia are rarely itchy or painful, but some may experience mild discomfort due to this condition. Milia may be irritated by friction such as rubbing against rough clothing.
Use of heavy skin care products may induce the formation of milia by trapping keratin under the skin's surface. Traumatic milia may also develop after damage or injury to the skin. Types of injury include burns, sun damage, blistering and deep skin resurfacing.
Milia are mainly an aesthetic concern and often resolve on their own over time. If persistent or bothersome, they may be extracted by an aesthetician or healthcare professional. If you are unsure whether a bump on your skin is a milium, it is best to consult with your doctor. The dermatologists at Cadogan Clinic are available for in-depth consultations to diagnose milia and provide effective treatment if required.
