How do wrinkles form?
Wrinkles are an inevitable part of the natural ageing process. There are two different types of wrinkles; dynamic wrinkles, which develop due to repeated muscle movements, such as smile lines around the mouth, and static wrinkles caused by environmental factors, lifestyle habits and the ageing process. Static wrinkles are visible even when your face is at rest and often deepen over time.
They are caused by a loss of skin elasticity, fat and collagen. The skin itself is made up of three layers. The epidermis layer on the surface is made up of dead skin cells and protects the body from outside elements such as water and sunlight.
Beneath this layer is the dermis, which is responsible for the skin’s strength and elasticity, as it’s rich in collagen and elastin fi bres. The base layer, known as the hypodermis, is where fat cells that give the skin its plump youthful appearance reside. Over time, wrinkles will start to form on both the epidermis and dermis layers. As we age, our skin cells take longer to divide, which means the skin repairs at a much slower rate than when it’s young. As a result of this, the dermis layer will begin to thin out, and fine lines start to form on the epidermis due to a loss of moisture.
Eventually, collagen and elastin will break down in the dermis layer, which reduces support so the skin is unable to ping back as quickly when stretched. Fat will also begin to deplete in the hypodermis layer, causing the skin to sag and appear much less plump.
