Healthy Skin Cell Growth – How it Works
As humans, we are made up of roughly 19 million skin cells on every inch of our body. The skin acts as the body’s protective layer from the environment and is the body’s largest and fastest growing organ. Your skin is your body’s coat, keeping you warm when it’s cold and cool when it’s hot. The skin also helps to keep all of the inner body held together from the heart and lungs to the blood and muscles.
The skin grows at a rapid pace making and losing skin cells every day. Though the formation of skin cells is a complex process, it is an important one to learn and understand. Skin cell growth stems from the basic concept of cell division. When cells divide and grow, they do so in a very precise manner so that the new cells are exact copies of the existing cell. Each cell makes copies of all its genes then splits into two with new sets of genes in each new cell. If more cells are needed, the new cells will rest for a while and then divide again. The cells carry on this process until enough cells have been made. Since the loss of skin cells is so rapid, generation of new cells almost never stops.
To better understand the process of cell division, it is important to understand the 2 main phases and the 4 stages of the cell cycle (G1, S and G2). The two main phases are known as the interphase and the mitotic phase. During interphase, the cell grows and makes a copy if it’s DNA. During the mitotic phase, the cell separates its DNA into two sets and divides to form two new cells known as daughter cells. In the interphase there are 3 main stages. First, during G1 stage, also known as the first gap phase, the cell grows physically larger and copies its organelles. Then in the S stage, also known as the synthesis stage, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a micro-tubule structure called the centrosome which helps to physically separate the DNA during the mitotic phase. During the second gap stage (G2), the cell grows more and beings to organize the inner cell contents for the mitotic phase.
The mitotic phase begins right when the G2 phase ends. In the mitotic phase, the cell divides its copies of DNA to make 2 new cells. The mitotic phase consists of 2 main processes known as mitosis and cytokinesis. During the mitosis process, the DNA of the cell condenses and is pulled apart by a special structure made out of microtubules called the mitotic spindle. The process of cytokinesis is the process of the cell splitting in two to form two new cells. Cytokinesis beings when mitosis ends.
At the end of the cell cycle, two new cells have formed from the original and contain exact copies of DNA. This process of cell division is the foundation for regenerating new skin cells on our body.
Understanding the process healthy skin growth is just the start. It’s important to understand how to promote healthy skin growth. Usage of high nutrient oils such as Moringa oil can help boost skin growth and health. Moringa oil, high in Oleic acid and antioxidants, penetrates deeply into the skin delivering vital nutrients for skin growth and repair. Such a complex cycle of cell growth and regeneration calls for healthy and nourished skin.
