What are comedones called when they are exposed to sunlight for long periods?

Comedones are essentially clogged hair follicles that can be open (blackheads) or closed (whiteheads). When our skin is exposed to sunlight for extended periods, certain changes can occur that affect the composition and appearance of comedones. The term "solar comedones" refers to a specific type of comedone that forms as a result of prolonged sun exposure. Factors such as increased keratin production and the influence of ultraviolet light can cause these comedones to form or become more pronounced.

Solar comedones often present as small, dark, or yellowish bumps on sun-exposed areas of the skin, highlighting the connection between sun exposure and the development of these specific clogged pores. Understanding this connection is important, as it underscores the significance of sun protection to prevent such conditions, along with their potential impact on overall skin health.
