👉 Aside pimples, also known as internal or internal comedones, are a type of acne lesion that forms beneath the skin's surface, often appearing as small, round, or irregular bumps. Unlike external pimples that form on the skin's surface, these occur when hair follicles become clogged with dead skin cells and sebum (oil) trapped beneath the surface. This blockage leads to inflammation and the formation of pimples. Aside pimples can be black or white in color, depending on the oxidation process within the clogged follicle. They are typically less visible than external pimples and can be a common issue, especially during hormonal changes or periods of increased oil production.
