Introduction

A healthy skin is a result of the adequate structure and functioning of several components of skin. In order to maintain a beautiful skin and to slow the rate of aging, all the functions and structures of the skin should be protected. It is the softest outer most surface of body.

Formation of Skin Cells

New skin cells are formed at the utmost layer of skin, which s called Epidermis. It is divided into five horizontal layers. It is formed in between 50 cell layers to 100 cell layers, from thin areas to thick areas. Epidermal width is usually of 0.1 millimeters, which is equal to the width of one paper sheet. It is considered as the defensive shelter of body and it gets renewed completely after every 28 days roughly. The first layer of epidermis is called the stratum basale. It is the deepest layer of epidermis and it appears exactly over the dermis. A single layers of stratum basale is consist of cells, which are of cube shaped. The new skin cells are called Keratinocytes, these are formed in stratum basale, which are formed through cell division in order to replace the shelter of the skin on a continuous basis from the upper layers of the epidermis. This is the process of skin cells renewal and it is formally called the Regenerative Process. ...
