Two kinds of cells can be recognized in the basal layer of the skin. One of these types of cells is a 'slow cycling cell', designated as a stem cell that gives way to the more rapid cells. The second type of cell is a 'rapid cycling cell', which is designated as a transit amplifying cell. This second type of cell is destined to undergo terminal specialization and leave the basal layer after a few cycles of mitosis. 'Keratinocytes' have the highest capacity contained by a single cell to reproduce independently. These create a colony in the human follicle, located in the region directly under the bulge (the entire permanent portion of the follicle, under the sebaceous glands).

Although it is thought that stem cells proliferate infrequently in an undamaged epidermis, they are the cells that are capable of sustained proliferation, in response to a stimulus such as wounding.

Glycoconjugates: Help reach the correct balance between the synthesis and degradation of crucial structural elements such as collagen and elastin, working toward a cure for damaged skin.

Collagenase: Enzymes that accelerate the degradation of collagen and gelatin.

Gelatinase activity: An enzyme that begins the hydrolytic rupture of proteins, usually by splitting them into polypeptide chains. These are required in early tissue repair and in prolonged tissue remodeling. Various kinds of matrix metalloproteinases (collagenase and gelatinase enzymes) are selectively expressed or activated at various stages of the skin regeneration process. These variations resolve the presence or absence of aberrant scars, like keloids or hypertrophic scars.

The matrix metalloproteinases (MMP) are a group of zinc-dependent enzymes, which degrade varying components of the extracellular skin matrix in both healthy and diseased tissue. The skin matrix is a framework that keeps the skin together and consists essentially of interlaced polymers such as collagen and elastin. The skin matrix is responsible for the skin's physical properties, including firmness and elasticity. The weaker and less consistent the matrix, the more wrinkles, roughness, and sag one tends to have over time. Whenever skin is injured, disfigured or worn out, the skin matrix is broken down by the MMP enzymes, and then recreated by fibroblasts. Therefore, MMP enzymes play a critical role in skin physiology.

Finding Fast Answers to Skin Care Issues

The modern approach to skin care is keeping up a healthy balance of these enzymes.

In healthy, youthful skin, the synthesis and degradation of the matrix have achieved a certain balance; a damaged or redundant matrix is degraded, while deficit qualities are replenished by the ongoing synthesis. Unfortunately, this intricate balance gets altered as one ages - too little of the matrix is synthesized and too much is degraded. MMP levels rise excessively the older one gets.

Research indicates that a reversal of MMP levels to regular youthful levels in aged sufferers is an effective way to eliminate the damaged matrix and keep the healthy one. With this objective in mind, the utilization of MMP inhibitors in the form of chemicals drugs, cosmetic formulations, and lifestyle changes is the latest cure for skin care concerns. Do it yourself, natural remedies for acne and other skin problems are effective, daily treatments that improve the skin's condition over time.
