Many people at some point notice tiny white bumps forming on their skin, often around the cheeks, nose, or under the eyes. These bumps are frequently mistaken for pimples or whiteheads, but in reality they are something quite different. Known medically as Milia, these small cyst-like formations develop when keratin, a protein naturally produced by the skin, becomes trapped just beneath the surface instead of shedding normally. Because keratin helps form the structure of hair, nails, and the outer layer of skin, the body constantly produces and sheds it as part of the natural skin renewal cycle. When that process is interrupted or blocked, keratin can accumulate inside tiny pockets beneath the skin, creating the firm white bumps commonly recognized as milia.

Although they may look similar to acne, milia are not caused by bacteria, clogged oil glands, or inflammation like typical pimples associated with Acne. Instead, they form as small cysts that remain trapped beneath the outer layer of skin. These bumps are harmless and non-contagious, meaning they do not indicate illness or infection. However, they can be frustrating because they tend to appear on very visible areas of the face, particularly around the eyes and upper cheeks where the skin is thinner and more delicate.
