The 3 Main Layers of the Skin and How They Work
In the world of dermatology, we often here a lot of medical terms thrown around, and different nomenclature used to describe different parts or areas of the skin. While we obviously don’t have the medical background of our dermatologists, we should try to be as knowledgeable as possible, as this can only help us to properly craft a skincare routine and better care for our skin. As the top dermatologist Astoria has to offer, Dr. Michael Gladstein tries to educate his patients as best he can on understanding the skin, as the better we know our skin, the better it will look and feel. This is a simple rule. Once you understand and are more aware of your skin, then you will understand exactly how to care for it. One of the most basic things to know about the skin is that it has three primary layers, with each layer serving its own unique purpose – when each of these three layers performs its specific function, our skin works like a well-oiled machine. To better understand the skin and its overall function, here is some important information to know about each of the skin’s three layers.
· The Epidermis
Throughout his many years as a dermatologist Astoria physician Michael Gladstein has helped countless patients deal with a variety of skincare issues, some start deep within the skin and others are more superficial, along the skin’s outer layer. The outermost layer of the skin is known as the epidermis – it acts as the body’s first line of defense against bacteria and other airborne, environmental intruders. The epidermis itself is actually broken into four other layers, they include:
1. Stratum Corneum – the topmost layer, varies in thickness depending on where along the body we are checking.
2. Stratum Granulosum – the cells here produce a waxy material that makes your skin waterproof.
3. Stratum Spinosum – the next layer is made up of cells that bind other cells together—like glue for your skin cells – essentially, a form of connective tissue.
4. Stratum Basale – the bottom layer of the epidermis, houses stem cells, which divide and produce new skin cells through cellular regeneration. These cells eventually get pushed to the skin’s surface and become the new surface cells.
· The Dermis
This is considered the action layer of the skin, where reactions and important proteins are located. The dermis is mostly made up of collagen and elastin, and certain vital cells known as fibroblast cells – the type of cell that creates collagen and elasticity within the skin cells at the surface). According to Dr. Gladstein, the top dermatologist Astoria has to offer, the dermis has a few different jobs including:
o Housing blood and lymph vessels, in charge of delivering nutrients to the skin and detoxifying the skin of harmful toxins.
o Housing the sweat glands, allowing us to sweat and acting as the body’s cooling system as well as to clear out toxins.
o Houses hair follicles, and anchors them to the oil glands. This oil is the oil that softens and acts as a coating for the skin.
· The Subcutaneous Layer
This is the inner layer of the skin, and essentially attached the bones to the muscles. In fact, the subcutaneous layer is so deep that no skincare products of topicals can ever reach down to that point. According to Dr. Gladstein, the top dermatologist Astoria has to offer, the main purpose of this layer is to:
o Act as a thermostat and adds fat padding to act as insulation, and energy reserves.
o The fat layer protects the muscles bones and inner organs against injury.
o Also contains blood vessels, nerve endings and the roots of the hair follicles above. In addition, it holds the deepest reserves for the sebaceous glands, additional oil for the skin.
