It is always nice to look at a baby’s flawless skin. There are no lines, no signs that a pimple has ever been there, and actually, the skin is perfect.
Oh my, where have those days gone for us!
So, getting on our topic, to understand what causes wrinkles, we must first know about the layers of our skin. Here they are:
This is the outer layer of your skin. Amongst many things, it protects the inner layers from any dangers in the outside environment.
This is the skin’s second layer. This contains its structural elements, which is the connective tissue. There are many types of connective tissue. Each has different function. Collagen, for example, gives the skin strength. The glycosaminoglycans are the proteins that give turgor to skin. The elastin fibers create the elasticity of your skin.
Also, between the dermis and epidermis is the dermal-epidermal junction. This is an important feature as it interlocks and forms fingerlike projections which are called rete ridges. These increase the area of the epidermis which is exposed to the blood vessels and need nutrients. The blood vessels in the dermis feed nutrients to the epidermis through the rete ridges.
3. Subcutaneous tissue
This is the skin’s bottom layer. And the subcutaneous tissue contains the fat cells. You know what those cells are for? They supply insulation to your body and they also make your skin full and plump.
The formation of wrinkles…
How then do wrinkles form and develop as we age?
There are a number of reasons for wrinkles. Here are some of them:
Through time, the epidermal cells become thinner. As a result, your skin looks thinner.
The epidermal cells also become less sticky. This means that that there are more chances for the moisture in your skin to be released than maintained, which causes dryness. The decrease in the epidermal cells is actually 10 percent per decade. And as people age, the cells divide slower. For this reason, the skin cannot cope as quickly as it used to in order to repair itself.
In the dermal layer, less collagen gets produced as we age. The elastin fibers also wear out. Such factors cause the skin to sag and wrinkle. The rete ridges, meanwhile, flatten out. This causes the skin to be fragile. And so the nutrients that the epidermis needs are not met accordingly.
As for the subcutaneous layer, the fat cells get thinner as we age. This results in more wrinkles and sagging.
And many outside factors can cause wrinkles, such as smoking, rapid weight loss, and especially overexposure to sun, which is a big factor.
Because so many factors contribute to wrinkling, one of the things we look for in wrinkle creams is how the ingredients address the different causes of wrinkles, and how many of the different causes the ingredients work on. The more, the better.
