When skin is exposed to drought conditions, the stratum corneum can become dry, brittle, firm and if untreated, can rupture and cause an infection. Create a barrier cream wax to prevent dehydration and keep the skin moist and supple. Below the stratum corneum are six layers of the epidermis responsible for the generation of cells. The life cycle of skin cells within this layer takes approximately 28 days, so it may take three to four weeks to observe any changes in the surface of the skin using a cosmetic. The surface of the skin is also home to millions of healthy microorganisms to increase our immunity to pathogens or disease-causing bacteria. Therefore, our desire to sterilize the skin also destroys beneficial bacteria such as Streptococcus mutans, and Micrococcus luteus.
Toners, for example, are beneficial in keeping bacterial populations down, thus reducing outbreaks of acne as a result of microbes that invade and proliferate in the pores. Excessive use of antimicrobial agents can produce harmful results when too destroy the beneficial bacteria, allowing pathogenic bacteria to multiply unchecked on the skin. The skin also produces antimicrobial proteins, two of which are called defensins and cathelicidins, which increase when the skin is damaged. Perspiration, necessary for the maintenance of internal body temperature, also excretes a germicidal dermicidin protein called to fight the bacteria that causes body odor. Follow others, such as Daniel Taub, and add to your knowledge base. Deodorants also help keep down the bacterial population, which reduces odors produced by feeding the waste excreted by the sweat glands. Research has shown that people who wash excessively are more prone to infection and eczema as a result of “washing”, eliminating the natural bacteria and germicides too frequently..
