Did you know that over 50% of the dust in your house is actually dead skin. This is happens because your epidermis mostly remains dead and falls off. Lipids are natural fats that keep the outer layer moist and healthy. Lipids can be destroyed by detergents and alcohol. Skin can be very delicate, vitamin A actually can treat sun damage and cellulite. Your skin each have 2 special features. The epidermis is waterproof and and dead, dermis is where the hair grows and its sweat glands, and the fat is fat and large blood vessels. Your skin is like a cage that keeps all your organs in place, like a bird cage that keeps the birds inside.

=Layers of The Skin.=

We have 3 main layers of our skin. Each layer does a different job. The layers are the epidermis, dermis, and the fat. The epidermis does one of the most important jobs for instance the layer of skin protects us from the world outside of us. Although the epidermis mostly remains dead it still helps us fight off infections and skin illnesses.On the other hand the middle layer is called the dermis. The dermis gives the epidermis the majority of its thickness. The dermis cushions the body from stress and strain. As the result the dermis is elastic tissue and it is also a thick layer of fibrous that allows the skin to have its flexibility. The dermis layer is what contains sweat glands, nerve endings, and oil glands.Returning to the last layer the fat. The fat plays a very important part of your skin. It attaches the dermis to the muscles and bones. Nerve cells and blood vessels start in the dermis, but as they get bigger they start to move throughout your body starting from the fat. This layer is the only layer that helps your body temperature stay not too cold or not to warm.

Over most of our body the epidermis is the thinnest. While on the palms of our hands and the soles of our feet the skin is thicker to give us padding. Where the location is the epidermis may contain hair follicles, nails, sweat and sebaceous glands. This is also a study known as dermatology.

=How Does Skin Recover?=

When your skin gets cut your body realizes right away and jumps into action to heal the cut. First, your body works really hard to limit your loss of blood by reducing the amount of blood running into the area that is cut. Fibrin, which is a protein in your blood, work with the blood platelets which is already in place and plasma to form a scab. A scab is a protective covering. Meanwhile your skin regenerates underneath the scab which protects the inside from outside infection.After this process the cut starts to heal as new granular and new skin tissues begin to form and come back.When skin recovers the tissues start at the edges of the cut and makes its way into the middle until the cut is fully covered up. A so you know a deeper cut will take longer to heal and is more likely to get infected.
