1. Stress is a huge player and stimulates the adrenal glands. The adrenal glands produce androgen and cortisol. The androgen hormones stimulate the sebaceous glands in the skin. The increase in oil secretion causes the dead cells within the pores to clump together yielding nasty inflamed eruptions on the skin. This tends to impact women more than men since females produce the majority of their male hormones in the adrenal glands.
2. Don't pick and excoriate your skin. You are not helping yourself and only making the situation worse - a lot worse. Leave the extractions to a licensed Professional; otherwise, more damage, injury, and the potential for scarring will result.
3. Overexposure to sunlight or getting a sunburn is not okay and should be avoided at all costs. The skin responds to a sunburn by increasing the production of cells to replace the damaged cells at the surface AND within the pore. This increase in cell proliferation can lead to an acne flare-up. In addition, the sun damages skin and accelerates cellular ageing.
4. Hot and humid weather exacerbates acne. The skin swells and expands under these two extreme conditions. You can do yourself a favor by avoiding steam baths too.
5. Heat, pressure and friction can induce acne lesions. Athletic gear, a tight waist band, and head wear are examples. Anything that continuously rubs the skin, constricts it, and leaves the skin wet and/or sweaty can cause problems.
6. A French endocrinologist named Alain Reinberg, M. D. who was an authority on chronobiology successfully demonstrated that human beings evolved to exhibit annual seasonal rhythms in testosterone production. Human testosterone levels are highest in October and lowest in May. These fluctuations are due to the amount of natural daylight. So you may experience more breakouts during autumn and winter.
7. Occupational hazards also exist for those that are exposed to industrial chemicals and oils. Chlorinated industrial chemicals, such as dioxin, are highly acnegenic. Coal tars used in the roofing industry and road works are another hazard. Mechanics and kitchen staff are exposed to grease and oils. Exposure to these substances can be by contact, ingested or inhaled.
