Milla, also known as milia, are small, white, cyst-like bumps that typically appear on the skin’s surface. These tiny, hard bumps form when keratin (a protein found in skin cells) gets trapped beneath the skin’s surface. While they are harmless, they can be bothersome, especially when they appear on your face. Milla commonly occurs around the eyes, cheeks, and nose but can appear anywhere on the body.
