The surface or visual layer of the skin is known in scientific terms as the stratum corneum. Stratum Corneum is a Latin meaning horned layer. The skin forms a protective barrier shielding the internal organs of the body from bacteria, germs, pollution and invading chemicals or influences. This outer layer not only keeps invading predictors out of the body but keeps moisture in. It can be considered the body’s first line of defense.
The skin is in a constant state of evolution and growth. The lower levels or those closest to the internal organs slowly work their way toward the surface or outer layer where they shed. This entire process normally takes about 14 days. In people with psoriasis this process speeds up and may be completed in 2 to 3 days and in rosacea, the process appears to remain on a standard 14 days cycle but the difference being that the body’s immune system produces more of these tryptic enzymes used to break down the outer layer of skin in preparation for shedding. The accumulation of excess tryptic enzymes can result in an increase in skin redness.
The theory of antibiotic use to treat rosacea symptoms is based on the activity of tryptic enzymes because antibiotics inhibit our immune system response effectively hindering the action of the enzymes and their ability to perform properly. Antibiotics can effective in addressing the some of the symptoms related to rosacea but this is only a short-term stop gap solution as the body adjusts to the antibiotic and thus renders it no longer effective.
