There can be several reasons for acne and impurities, and there are different types of acne. Pimples can have varying degrees of inflammation. Pimples that become red and possibly with sebum/pus are local inflammatory reactions in the skin, where bacteria contribute to the problems. The inflammatory reaction in the skin weakens the skin's barrier function, so that the skin's resistance and protective function are reduced. The skin's barrier against the environment is an important part of the skin's own defence, and has an important function in ensuring the skin's moisture level and protecting the skin against influences from wind, weather, UV rays and air pollution. When the barrier function weakens, the skin becomes 'leaky' and loses moisture. This can make the skin loose, dry, sensitized and irritated. Such skin also becomes more susceptible to bacterial infections that worsen acne tendencies. To counteract the dryness, the skin compensatory increases sebum production. This contributes to clogged pores, impurities, irritation and pimples and the skin becoming shiny.
People with a tendency to blemishes and acne often clean their skin a little too hard. Unfortunately, this causes further wear and tear on the skin's barrier function and a further weakening of the skin's resilience. One is therefore easily caught in a vicious circle with irritated, pimpled skin, with elements of dry areas and oily areas.
