Pimples are a common skin concern. While often just a bump, a pimple can sometimes bleed, which may be surprising. This bleeding is a natural bodily response to skin disruption.
The Anatomy of a Pimple
Pimples begin when hair follicles become obstructed. This blockage occurs due to excess oil (sebum), dead skin cells, and bacteria. Sebaceous glands, located within the dermis, produce sebum. When pores clog, bacteria, specifically Cutibacterium acnes, multiply. This bacterial overgrowth, combined with trapped sebum and dead skin cells, triggers an inflammatory response, leading to the swelling and redness of a pimple.
The skin contains a network of tiny blood vessels, capillaries. These capillaries are located close to the surface, within the dermis. The inflammatory process of a pimple causes these blood vessels to enlarge and become more permeable, increasing blood flow. This vascular activity contributes to the redness and warmth around an inflamed pimple.
Why Bleeding Occurs
Bleeding from a pimple results from physical trauma to the inflamed area, often caused by squeezing, picking, or rubbing. When pressure is applied to a pimple, it can rupture the delicate capillaries within the lesion. The inflammation makes these blood vessels more fragile and engorged, making them more susceptible to bursting.
The act of squeezing a pimple forces out its contents. This forceful expulsion also traumatizes the surrounding tissue, causing the underlying blood vessels to break and release blood. Deeper or more severely inflamed pimples are more prone to more bleeding because they involve deeper vascular networks within the skin. The bleeding is the body’s natural response to this minor injury, indicating damage to the small blood vessels.
After a Pimple Bleeds
After a pimple has bled, manage the area to promote healing and minimize complications. Begin by gently cleaning the affected skin with mild soap and water or an antiseptic. To stop the bleeding, apply gentle, direct pressure to the area using a clean cloth or tissue. If bleeding persists, applying ice wrapped in a clean cloth can help constrict blood vessels and reduce further bleeding and swelling.
Avoid further squeezing or picking at the pimple after it has bled, as this can introduce more bacteria, worsen inflammation, and increase the risk of infection and scarring. Signs of infection include increased redness, swelling, pus, or pain that worsens. If these signs develop or if the pimple does not heal properly, seeking advice from a healthcare professional is recommended. The body possesses a natural healing process for minor skin injuries, and providing a clean, undisturbed environment supports this recovery.
