What are the biofeedback mechanisms going on in the skin?

Dr. Ellen Marmur, MD
Dermatology
There are definitely amazing biofeedback mechanisms going on in your skin all the time. Those tireless inflammatory cells go into action to repair the stratum corneum when it is wounded by a sunburn, a scrape, or excessive dryness caused by too much washing, which strips the skin of natural oils. But those internal systems are not so specific that they would stimulate oil production on parched skin, and no research makes this claim. Dry skin may instigate pimple production, however, as an inflammatory stress reaction. And drying out the skin may clog pores with dead keratinocytes (which helps to create an acne situation), but it doesn't activate the sebaceous glands.
