Why Some Pimples Never Come to a Head
You know those stubborn pimples that sit under your skin, feeling hard and sore but never rising up with a white tip you can squeeze? These are not your typical zits. They are called nodules or cysts, and they form deep inside the skin where you cannot easily reach them.[3][4]
Regular pimples, like whiteheads or pustules, start when oil, dead skin cells, and bacteria clog a pore near the surface. The pore gets blocked but stays somewhat open or closed just under the top layer of skin. This lets pus build up and push toward the surface, forming a head that looks ready to pop.[4] Nodules and cysts skip that step. They develop far deeper in the dermis, the skin’s thicker middle layer. There, inflammation swells around the clog without creating a visible point or pus pocket that breaks through.[3][4]
What causes these deep troublemakers? Hormones play a big role. Androgens, which are male hormones present in everyone, can spike and tell oil glands to overproduce sebum. Too much oil mixes with skin cells and bacteria, trapping everything deep down.[2][3][4] This often happens along the jawline, chin, or cheeks, especially in women during periods, pregnancy, PCOS, or menopause.[1][2][3] Stress adds fuel by raising cortisol, another hormone that boosts oil and inflammation.[3]
Bacterial infections can also drive nodules if they burrow deep before your skin fights back.[4] Unlike surface pimples, these do not drain easily. They can last weeks, hurt a lot, and leave scars if irritated.[3][4]
You might notice them more as an adult. Adult acne over 30 often shows up this way due to shifting hormones, not just teen oiliness.[2] Face mapping, an old idea, links spots to body issues like gut problems or hormones, but doctors focus more on the deep clog and swelling.[1]
Handling them takes care. Skip popping; it spreads infection deeper and worsens scars.[5] Gentle cleansers, oil-free products, and ingredients like salicylic acid help mild cases. For bad ones, see a dermatologist for prescriptions that target hormones or inflammation.[2][4]
