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 meant to undergo terminal specialization and leave the basal layer after a few cycles of mitosis. 'Keratinocytes' have the highest ability contained by a single cell to proliferate independently. These create a colony in the human follicle, located in the region directly below the bulge (the entire permanent portion of the follicle, below the sebaceous glands).

Although it is thought that stem cells divide infrequently in a healthy epidermis, they are the cells that are capable of continued proliferation, in response to a stimulus like wounding.

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

Collagenase: Enzymes that catalyze the hydrolysis of collagen and gelatin.

Gelatinase activity: An enzyme that begins the hydrolytic breakdown of proteins, normally by splitting them into polypeptide sequences. These are involved in early tissue repair and in extensive tissue remodeling. Several kinds of matrix metalloproteinases (collagenase and gelatinase enzymes) are selectively expressed or activated at different periods 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 group of zinc-dependent enzymes, which degrade varying components of the extracellular skin matrix in both normal 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 mechanical properties, including firmness and suppleness. The weaker and less consistent the matrix, the more wrinkles, roughness, and sag one tends to acquire 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 dermal physiology.

At-Home Solutions to Skin Care Concerns

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

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

Research shows that a reversal of MMP levels to normal youthful levels in aged sufferers is an efficient way to remove the flawed matrix and keep the healthy one. With this objective in mind, the utilization of MMP inhibitors in the format of chemicals drugs, cosmetic solutions, 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.
