Skin explainedThe skin is the largest organ in the human body and its primary function is to act as a barrier. It protects our internal organs, muscles, and bones from the external environment, while also preventing dehydration and infection. The skin also helps to regulate body temperature, provides sensation, and produces vitamin D when exposed to sunlight. Additionally, the skin helps to excrete toxins and waste products via perspiration. The skin is composed of multiple layers of cells, including the epidermis, dermis, and hypodermis. Each of these layers provides specific functions to ensure the overall protection of our bodies. |  |
It is the outer most layer of the skin and is constantly renewing. The lowest level of the epidermis, the basal layer, consist of cells that continually divide and push new cells towards the surface of the skin. As the cells move upwards, they gradually lose their nucleus and become filled with a protein called keratin. This results in the cells producing an outer cornified protective layer (stratum corneum), which is continuously worn away and replaced.
The dermis is situated between the epidermis and the subcutaneous layer and is composed of two layers; the upper papillary layer and the lower reticular layer. The dermis consists of dense collagen and elastin fibres that give your skin strength. It contains a network of blood vessels, sweat glands, hair follicles, sebaceous glands and nerve endings. It also plays a major role in skin health and function. It helps provide nutrients to the epidermis, regulates temperature, and provide sensations.
The hypodermis, Also known as the subcutaneous layer, is situated at the bottom of the skin. It is comprised of adipose tissue and loose connective tissue. The hypodermis has many important functions, including storing energy, providing insulation to our body and protecting our internal organs from injury.
What is the Fitzpatrick scale?A Fitzpatrick Scale is a tool used to assess a person’s skin tone and colour, which is important for determining which aesthetic treatments and products are best suited for them. It is a six-level numerical classification system developed by dermatologist Thomas B. Fitzpatrick, and it is based on skin reaction to sun exposure. The scale runs from 1 (very fair skin) to 6 (deeply pigmented skin). The Fitzpatrick Scale is used in a variety of aesthetic procedures to help ensure the best possible outcome. For example, it helps determine the best type of chemical peel, which laser hair removal can be used safely, and what type of sunscreen should be used. The Fitzpatrick Scale is an important tool for ensuring that aesthetic treatments are safe and effective for the individual. By assessing a person’s skin tone and colour, it can help ensure that the best possible outcome is achieved. |
Skin typesKnowing your skin type is important, as it helps determine which products and or treatments you’ll benefit from. Our skin type is determined by our genetics. However, the condition of our skin can vary greatly according to the various internal and external factors it is subjected to.
