One of the main problems with sleeping in makeup is that the residue can mix with the sebum and sweat produced by the skin. This can clog pores and contribute to blackheads, whiteheads, and acne breakouts , especially in people with oily or acne-prone skin.
Furthermore, some cosmetic products can remain on the skin’s surface for hours. If not removed properly, they can contribute to irritation, particularly for those with sensitive skin.
Clogged pores and imperfections
When pores accumulate oil, dead skin cells, and product residue, different types of skin imperfections can appear . In some people, this manifests as small pimples, while in others, larger inflammatory lesions may develop.
However, it’s important to avoid automatically attributing a case like the one in the photograph solely to makeup. Inflammatory acne can be related to multiple factors, including genetics, hormones, certain medications, stress, and specific skincare products.
