Skin is more than a fleshy surface for pimples, tattoos, and wrinkles. Skin is the body's largest organ, and along with hair, nails, glands, and nerves, is part of the integumentary system, according. This system acts as a protective barrier between the outside and the inside of the body.
In adults, skin accounts for about 16 percent of total body weight and covers a surface area of approximately 22 square feet (2 square meters).
There are different thicknesses and textures of skin on different parts of the body. For example, skin is paper-thin underneath the eyes but is thick on the soles of the feet and palms of the hand, according.
The epidermis is the top, visible layer of skin and it's constantly being renewed as dead skin cells are shed on a daily basis. The main functions of the epidermis include:
Protecting skin. Keratin, a protein made by cells found in the epidermis, gives skin its toughness and strength and protects skin from drying out.
The dermis is the middle layer of skin, found underneath the epidermis. It is the thickest layer of skin and contains nerves and blood vessels. It is also home to sweat glands, oil glands, and hair follicles. The dermis gives skin flexibility and strength, according. It is made up mostly of a protein called collagen that makes skin stretchy and strong.
Growing hair. Hair follicles found in the dermis grow the hair on your head, face, and body. That hair also helps to control body temperature and protect the body from injury.
The hypodermis, also called subcutaneous fat, is the deepest layer of skin. This layer is made up mostly of fatty tissue, which helps to insulate the body from heat and cold. The hypodermis also serves as an energy storage area for fat. This fat provides padding to cushion internal organs as well as muscle and bones and protects the body from injuries, according.
The good skincare, including sun protection and gentle cleansing, can keep your skin healthy and glowing.
You can still pamper yourself by acing the basics. Good skincare and healthy lifestyle choices can help delay natural aging and prevent various skin problems.
One of the most important ways to take care of your skin is to protect it from the sun. A lifetime of sun exposure can cause wrinkles, age spots, and other skin problems, as well as increase the risk of skin cancer.
Use sunscreen. Use a broad-spectrum sunscreen with an SPF of at least 15. Apply sunscreen generously, and reapply every two hours, or more often if you're swimming or perspiring.
Seek shade. Avoid the sun between 10 a.m. and 4 p.m., when the sun's rays are strongest.
Cover your skin with tightly woven long-sleeved shirts, long pants, and wide-brimmed hats. Also consider laundry additives, which give clothing an additional layer of ultraviolet protection for a certain number of washings, or special sun-protective clothing, which is specifically designed to block ultraviolet rays.
Smoking makes your skin look older and contributes to wrinkles. Smoking narrows the tiny blood vessels in the outermost layers of skin, which decreases blood flow and makes skin paler. This also depletes the skin of oxygen and nutrients that are important to skin health.
Smoking also damages collagen and elastin, the fibers that give your skin strength and elasticity. In addition, the repetitive facial expressions you make when smoking, such as pursing your lips when inhaling and squinting your eyes to keep out smoke, can contribute to wrinkles.
In addition, smoking increases your risk of squamous cell skin cancer. If you smoke, the best way to protect your skin is to quit. Ask your doctor for tips or treatments to help you stop smoking.
Daily cleansing and shaving can take a toll on your skin. To keep it gentle:
Limit bath time. Hot water and long showers or baths remove oils from your skin. Limit your bath or shower time, and use warm, rather than hot, water.
Avoid strong soaps. Strong soaps and detergents can strip oil from your skin. Instead, choose mild cleansers.
Shave carefully. To protect and lubricate your skin, apply shaving cream, lotion, or gel before shaving. For the closest shave, use a clean, sharp razor. Shave in the direction the hair grows, not against it.
After washing or bathing, gently pat or blot your skin dry with a towel so that some moisture remains on your skin.
Moisturize dry skin. If your skin is dry, use a moisturizer that fits your skin type. For daily use, consider a moisturizer that contains SPF.
A healthy diet can help you look and feel your best. Eat plenty of fruits, vegetables, whole grains, and lean proteins. Some research suggests that a diet rich in fish oil or fish oil supplements and low in unhealthy fats and processed or refined carbohydrates might promote younger-looking skin. Drinking plenty of water helps keep your skin hydrated.
Uncontrolled stress can make your skin more sensitive and trigger acne breakouts and other skin problems. Take steps to manage your stress. Get enough sleep, set reasonable limits, scale back your to-do list and make time to do the things you enjoy.
