Our skin is technically the biggest organ in our body. Not only does it serve as a natural barrier from the environment, it keeps everything contained, warm and hydrated. It is a complex structure with a series of layers, each serving a specific purpose. There are also many auxiliary features, such as hairs and glands, which are connected to chemical signaling networks to fulfil their function, such as in light-touch sensations.
A notable aspect of the skin is that its appearance and function is correlated to our overall health. With good nutrition, hydration, and physical activity, the cellular components of the skin can function optimally, performing maintenance as necessary. Exposure to the environment results in gradual degradation, especially because of accidental trauma, temperature, humidity, ultraviolet (UV) rays from the sun, and pollutants.
Over time, changes occur across all layers of the skin. Perhaps the most noticeable changes are on the face, where there is the most sun exposure, and constant movements of facial muscles and gravity contribute to changes in facial contour. With age, the ability for the skin to repair itself and replace cell structures is gradually reduced. Slowly, minor cracks between the layers cause a build-up of dead cells, which may obstruct the normal maintenance functions.
Wrinkles occur in three forms – surface, permanent, and deep. Surface wrinkles are common and very fine, occurring in the top layer of skin, typically because of facial muscle movements. Permanent wrinkles appear when the dermis becomes less elastic with a decrease of collagen. Finally, deep wrinkles are those that initially only appear with facial expressions, but after a lifelong of smiling and frowning, the wrinkles become ingrained into the skin.
To help reduce the appearance of skin aging, it’s important to protect yourself from harmful environmental exposure such as pollutants or UV rays. Sunscreen with an appropriate SPF should be applied when anticipating a long day in the sun. Also, a diet containing all necessary nutrients will ensure that the body has all it needs to maintain strong, healthy skin.
After establishing a healthy lifestyle, some skincare routines and products may be helpful. Various formulations may be more targeted for managing different signs of aging, so it may be helpful to consult with a health expert. Generally, it is recommended to use moisturizing agents containing a glycol, hyaluronic acid, and an active compound that helps keep water within the skin. Glycols help by adding some natural flexibility to the natural keratin proteins in the skin, while hyaluronic acid carries water to ensure hydration within the body’s connective tissue.
