The physiology of wrinkles is based on the composition of the skin and the aging process. In order to understand how and why wrinkles form, it is necessary to first understand more about the skin itself and how it changes when you age. Although aging is a natural process, there are some things you can do to combat the development of wrinkles.
Skin Layers
The skin is the protective layer that protects your body. It is what gives you the sense of touch and it helps to regulate your body temperature. Although the body ages in many ways, the changes in your skin may be the most noticeable; this is usually noted in the formation of wrinkles.
The Campaign for Aging Research explains that your skin is made up of three layers and each skin layer has a distinct purpose. The outermost layer is the epidermis. This layer protects the body from harmful germs and bacteria. This layer of skin is actually made up of several layers of kerotinocytes. It is in this layer that you will find sweat glands, which help to keep the body cool. This layer of skin helps to funnel waste out of the body, and it is also this layer that shows visible signs of aging.
The middle layer of skin is the dermis. This is where collagen and elastin are stored. These elements are essential for helping the skin retain firmness and elasticity. This layer helps to regulate the heat on the body's surface. It is also where you will find hair follicles and oil glands.
The third, or inner skin layer is the subcutaneous layer. This layer contains blood vessels and fat. This skin layer is responsible for regulating evaporation and hindering water loss.
Natural Aging Process
Along with the natural aging process, there are changes in the skin layers. This includes a thinning of the layers, which can result in loose skin that is not quite as firm and smooth as it used to be. Lines and crevices, better known as wrinkles, can develop. According to information at the Medline Plus website, as you age, everything slows down a bit, including the production of oil that moisturizes the skin and the supply of nutrients that keeps it rejuvenated. Even the fat becomes depleted, so there is less cushion.
Influential Factors
Not surprisingly, genetics plays a role in the aging process. But other factors that can have an impact include the level of stress you deal with regularly, and your body weight. Ultimately, living a happy and healthy lifestyle is one of the best ways to keep a youthful appearance.
Considerations
Exposure to ultraviolet radiation can drastically speed up the aging process, and it is a major cause for early wrinkling. Ultraviolet light breaks down the skin's collagen and elastin, which is the connective tissue. This is what prevents the skin from sagging and gives it flexibility, says the Mayo Clinic.
Even repeated facial expressions can eventually result in the formation of fine lines and wrinkles. As aging continues and the skin has less elasticity, it has less ability to spring back. Therefore, these lines can become the permanent features we refer to as wrinkles.
Wrinkle Prevention
You may not be able to prevent all wrinkles, but there is a lot you can do to slow them down. Begin your wrinkle prevention care early and make it a regular routine to be aware of ways to protect your skin.
Protection from the ultraviolet rays of the sun is always important, but especially during the middle part of the day when the rays are their strongest. Sunscreens should always be used liberally and often.
Smoking can add to the risks for early wrinkling. As you pucker your lips around a cigarette, you add to the lines that form on your face. Smoking itself results in health concerns that can indirectly lead to more wrinkles. Additionally, smoking can have an impact on your stamina and therefore on the amount of exercise that you get. Exercise and a healthy diet are always important. A diet that includes plenty of fruits and vegetables will provide natural antioxidants, according to the DermNet NZ website.
Your wrinkle prevention regimen should include regular use of sunscreen and moisturizer along with a healthy diet and exercise routine. A healthy lifestyle and proper skin care can help to prevent wrinkles and keep your skin younger and healthier.
