If you want to know what causes wrinkles, you need to understand what your skin is made of. It has basically three layers. The first two layers are the epidermis and the dermis, while the other one is the subcutaneous tissue.
The epidermis happens to be the skin’s outer layer, which plays the role of a fence protecting the skin from the surrounding environment. This layer has cells called keratinocytes, which shift from the epidermis’ bottom layer to the upper layer. This builds a considerable chunk of keratin, which converts into a tough feeling outer shell. When such cells manage to reach the skin’s top layer, they’ll just flake off. But when this procedure becomes totally abnormal, your skin starts to look scaly.
The 2nd layer is the dermis. It contains the skin’s essential structural elements – the vital connective tissues. There’re a lot of vital connective tissues playing different functions. For instance, collagen provides the skin with strength. It offers proteins that are known as glycosaminoglycans. These provide your skin with the essential turgor, whereas the elastin fibers can provide the skin with the essential elasticity. And many people do not know that the Dermal-Epidermal Junction is also crucial for understanding what causes wrinkles. The underlying junction that lies between the skin’s dermis and its epidermis is crucial. This junction interlocks and forms fingerlike projections that are known as rete ridges. These epidermis cells receive nutrients from your blood vessels that are found inside the dermis. Those rete ridges ultimately develop the epidermis surface that becomes connected to the blood vessels and get the essential nutrients.
The skin’s base layer is the special subcutaneous tissue that contains fat cells. Such fat cells can provide enough insulation to your body and ensure that your skin appears nourished and hydrated.
So what causes wrinkles? To help you understand the real scenario, we will discuss the aspects of Chronological Aging and the seemingly inevitable wrinkles that come by. As you age, your epidermal cells turn thinner and much less sticky. Then again, the thinner cells can ensure that your skin tone appears noticeably even. Your skin cells’ reduced stickiness ultimately decreases the efficiency of the underlying barrier that allows the moisture to get released, rather than being held inside the skin. This results into unwanted dryness. Then again, the total ratio of the epidermal cells tends to get lower by as much 10% each decade. Ultimately, they start dividing more slowly than before as you age. This makes your skin much less capable to repairing itself quickly.
The underlying effects of progressive aging on your dermal layer become significant. This only impacts the skin’s dermal layer. However, this also results into lower production of collagen. Then again, the underlying elastin fibers providing elasticity starts to wear out. Such changes in your skin cause it to get wrinkled and look sagged. There are some remedies that help reverse these things. You can use an OTC solution or a home made remedy to prevent aging effects now as you know what causes wrinkles.
