# An Overview of the Skin

3 min read

Your skin is the largest organ on your body, made up of several different components, including water, protein, lipids, and different minerals and chemicals. If you're average, your skin weighs about six pounds. It's job is crucial: to protect you from infections and germs. Throughout your life, your skin will change constantly, for better or worse. In fact, your skin will regenerate itself approximately every 27 days. Proper skin care is essential to maintaining the health and vitality of this protective organ.

## How Can I Keep Skin Healthy?

- Thorough cleansing. You should perform this twice daily. At night, make sure you remove all your make-up and cleanse properly before going to bed.
- Use a gentle soap without fragrance.
- Balanced nutrition .
- Moisturizing. This is recommended even for those who have oily skin. There are plenty of moisturizers on the market that are oil-free.
- Sunscreen . This is probably the most important thing that you can do for your skin. Even in the winter and on cloudy days, you should put sunscreen on every day. This should be done even if you are not outside much. A sunscreen that says “broad spectrum” (or says it protects against “UVA and UVB”) with an SPF of 30 or higher is necessary. Limiting your time in the sun, especially between the hours of 10 a.m. and 4 p.m., and wearing protective clothing, such as a long-sleeved shirt, pants, and a wide-brimmed hat, are also recommended.

Over the course of your life, you should pay attention to all parts of your skin. Familiarize yourself with it, so you'll notice any changes that might occur, such as different moles or patches that might indicate skin cancer. Whenever you have a question or concern, make sure you see your doctor.

## How Does My Skin Work?

There are medical terms for various parts of your skin. Here's a rough guide to what those terms mean.

## Stratum corneum: The Outer Layer of Dead Skin

The stratum corneum contains dead skin cells that used to exist in the epidermis. Using facial scrubs and some other skin products will remove or thin this layer.

## Epidermis: The Outer Layer of Skin

The epidermis is the thinnest layer in your skin, but it's responsible for protecting you from the harsh environment. The epidermis has five layers of its own. It also hosts different types of cells: keratinocytes produce the protein known as keratin, the main component of the epidermis. Melanocytes produce your skin pigment known as melanin. Langerhans cells prevent foreign substances from getting into your skin.

## Dermis: The Middle Layer of Skin

This is the layer responsible for wrinkles. The dermis is a complex combination of blood vessels, hair follicles, and sebaceous (oil) glands. Here, you'll find collagen and elastin, two proteins necessary for skin health because they offer support and elasticity. Fibroblasts are the cells you'll find in this layer, because they synthesize collagen and elastin. This layer also contains nerves that sense pain, touch, and temperature.

## Subcutis: The Skin's Fatty Layer

Reduction of tissue in this layer is what causes your skin to sag as well as wrinkle. This layer hosts sweat glands, and fat and loose connective tissue. The subcutis is responsible for conserving your body's heat and protecting your vital inner organs.

## Collagen and Your Skin

Collagen is found in the dermis and is the most abundant protein in the skin, making up 75% of this organ. This is also your fountain of youth. It's responsible for warding off wrinkles and fine lines. Over time, environmental factors and aging diminish your body's ability to produce collagen and can also break down existing collagen.

## Your Skin and Elastin

When you hear the word elastin, think elastic. This protein is found with collagen in the dermis, and is responsible for giving structure and support to your skin and organs. As with collagen, elastin is affected by time and the elements. Diminished levels of this protein cause your skin to wrinkle and sag.

## Keratin and Your Skin

Keratin is the strongest protein in your skin. It's also dominant in hair and nails. Keratin is what forms the rigidity of your skin.
