More than one kind of skin cell units are located within the basal layer of the human skin matrix. One of these types of cells is a 'slow cycling cell', assigned as a stem cell that gives way to the more rapid cells. The second type of cell is a 'quick cycling cell', which is assigned as a transit amplifying cell. This second type of cell is destined to undergo terminal differentiation and leave the basal layer after a few cycles of mitosis. 'Keratinocytes' have the highest capacity contained by a single cell to proliferate independently. These form a colony in the human follicle, located in the region directly below the bulge (the entire permanent section of the follicle, below the sebaceous glands).

Although it is commonly understood that stem cells proliferate infrequently in an undamaged epidermis, they are the cells that are capable of continued proliferation, in response to a stimulus like wounding.

Glycoconjugates: Help reach the correct equilibrium between the production and degradation of crucial structural elements like collagen and elastin, working toward a cure for damaged skin.

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

Gelatinase activity: A protease that starts the hydrolytic rupture of proteins, usually by splitting them into polypeptide sequences. These are required in early tissue repair and in extensive tissue remodeling. Various types of matrix metalloproteinases (collagenase and gelatinase enzymes) are selectively expressed or activated at different stages of the skin regeneration process. These variations determine the presence or absence of abnormal scars, like keloids or hypertrophic scars.

The matrix metalloproteinases (MMP) are a type of zinc-dependent enzymes, which eliminate several 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 mainly of interlaced polymers like collagen and elastin. The skin matrix is responsible for the skin's physical properties, including strength and suppleness. The weaker and less regulated the matrix, the more wrinkles, roughness, and sag one tends to have over time. Whenever skin is damaged, disfigured or worn out, the skin matrix is broken down by the MMP enzymes, and then recreated by fibroblasts. Therefore, MMP enzymes have a crucial role in dermal physiology.

Finding Fast Answers to Skin Care Issues

The latest approach to skin care is keeping up a healthy equilibrium of these enzymes.

In normal, youthful skin, the production and degradation of the matrix have achieved a certain equilibrium; a damaged or redundant matrix is eliminated, while deficit qualities are replenished by the ongoing production. Unfortunately, this intricate balance gets disrupted as one ages - too little of the matrix is produced and too much is eliminated. MMP levels rise exaggeratedly the older one gets.

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