Recognizing the Anatomical Layers of the Skin and Its Supporting Nutrients

Not as simple as it seems, the human skin anatomy consists of several layers with different functions. In order to function optimally, the skin also needs nutrition

Skin is one of the largest organs in the human body which covers almost the entire surface of the body. Skin has a thickness that can vary from person to person, depending on gender, age, and other factors such as certain medical conditions.

In general, men's skin is thicker than women's skin, and children's skin is thinner than adult skin. The skin also has various functions, including:

  • Protect muscles, bones, and other organs in the body
  • Protect the body from germs, viruses, and exposure to chemicals
  • Maintain fluid and electrolyte balance
  • Helps the synthesis of vitamin D
  • Keeping body temperature stable
  • Feel the sensation of pain and touch

Skin Layers

Skin is a dynamic organ that constantly changes as long as a person lives. The layer that is on the inside will replace the outer layer that has fallen off without realizing it.

The following is the anatomical structure of human skin which consists of three layers of skin, starting from the outermost layer:

1. Epidermis

The first anatomical structure of human skin is the epidermis. The epidermis layer has no blood vessels. Nutrient supply and disposal is obtained from the deeper layer, namely the dermis. The epidermis consists of several layers of cells called the stratum, namely:

  • The stratum corneum, which is a layer consisting of hard horn cells formed from keratin. The outermost layer of the skin functions to absorb water and protect the deeper layers of the skin.
  • Stratum lucidum, which is a thin layer that is only found on the thick skin on the palms of the hands and feet. This layer serves to reduce friction between the layers of the epidermis.
  • Stratrum granulosum, the third layer of the epidermis that functions to form skin protective cells.
  • Stratum spinosum, which is part of the epidermis that plays a role in creating keratin, which is the building block for skin, hair, and nail cells.
  • Stratum basale, which is the deepest layer in the epidermis that actively forms skin cells. In this layer there are melanocytes, which are skin color-forming cells (pigments) that function to protect the skin from UV radiation.

In the anatomy of the skin, in the epidermis there are also Langerhans cells which act as part of the skin's immune system and function to make the skin sensitive to touch.

2. Dermis

The second layer in the anatomical structure of human skin is the dermis. The dermis supports the epidermis and has a more complex structure. The structure of the dermis consists of elastic fibers, reticular fibers, and collagen fibers.

In addition, the dermis also contains blood vessels along with nerve endings, the lymphatic system, sweat and oil glands, hair follicles, connective tissue, and skin immune cells.

The dermis plays an important role in maintaining skin elasticity and maintaining a prime skin condition.

3. Hypodermis

The third layer in the anatomical structure of human skin is the hypodermis. The hypodermis is below the dermis layer and functions to attach the skin to muscles or bones.

The hypodermis itself is no longer part of the skin layer. In this layer, there is fat tissue that provides a cushion, protects the body from heat and cold, and serves as a storage area for energy.

Skin Supporting Nutrients

In addition to recognizing the anatomical structure of the skin, it is also important to know what nutrients can maintain the he alth of each layer of the skin. The skin needs nutrients in order to function optimally because changes in nutrient intake can affect the condition of the skin.

Some of what nutrients can support skin he alth are:

1. Vitamins

Vitamins needed for he althy skin include vitamins A, C, E, D, and K.

Vitamin A helps the process of forming keratin in the outermost layer of the skin, overcoming skin damage caused by UV exposure, and reducing wrinkles. As an antioxidant, vitamin C will help the process of collagen synthesis and protect the skin from UV rays.

In addition, vitamin E is also needed to help the skin deal with free radical damage and protect it from sun exposure. Vitamin D to help the immune system and the skin repair process.

The last is vitamin K which helps heal wounds, bruises, and areas affected by surgery. Vitamin K is also thought to relieve or treat certain skin conditions, such as stretch marks, scars, dark spots, and stubborn circles under the eyes.

2. Antioxidant

To control the damage to the skin caused by free radicals, consume foods that contain antioxidants. Some foods that are rich in antioxidants are pomegranate, dried fruit, strawberries, cauliflower, beets, tomatoes, nuts, cinnamon, and bell peppers.

3. Omega-3 fatty acids

Omega-3 fatty acids are also important for keeping the outer layer of the skin strong. Omega-3 can be obtained from salmon, mackerel, sardines, tuna, and nuts, or foods that have added omega-3 content.

Maintaining the he alth of each layer in the anatomy of the skin can be done with sufficient supporting nutrients. In addition, avoid direct sunlight and use sunscreen when doing activities in the hot sun. Do not hesitate to consult a dermatologist, if you experience complaints.
