<unk>  specifically is triggered by both<unk> l and heat stress on the skin working together to cause this irritation. The skin that is exposed to these stressors initially develops a harder surface to protect itself, but if the skin is continually dealing with this pressure, it gets irritated and forms a rash. At this point, it gets qualified as<unk> . When you are in a hot climate or are working out and your body temperature rises, the heat causes the pores in your skin to open up. The dilation of the pores makes it easier for bacteria, oil, and dead skin cells to collect in the pores and clog them. Every pore in your body has a tiny hair follicle, and the blockage causes the hair follicle to become irritated and inflamed, which ends up forming pimples; specifically<unk> . White blood cells flood the area of inflammation, and once they die, they accumulate on the surface of the pore, causing what is known as a “whitehead”. When people pop pimples, pus comes out, which has the dead white blood cells in it that originally came to diffuse the inflammation. Depending on the continuation of the stressors, the inflammatory pimples (also known as papules and pustules) can develop into nodules and cysts, which are more severe forms of<unk>  that are rooted deeper within the skin.
