As we mature our skin changes and we begin to develop fine lines and wrinkles, the skin texture is less smooth, we produce less collagen and the quality of this collagen is reduced. Much of the damage is caused through sun exposure and inadequate sun protection, other lifestyle factors which significantly affect the skin quality are sun bed use and smoking.
Before / After
How is the skin affected by sun exposure ?
The sun’s heat dries out areas of unprotected skin and depletes the skin’s supply of natural lubricating oils. In addition, the sun’s ultraviolet (UV) radiation can cause burning and long-term changes in the skin’s structure. An easy way to remember UVA cause aging and UVB cancer causing therefore it is important that the sunscreen is UVA and UVB and at least a factor 30.
- Dry skin
Skin can gradually lose moisture and essential oils, making it appear dry, flaky and prematurely wrinkled, even in younger people.
This term refers to a skin injury that appears immediately after the skin is exposed to UV radiation. Mild sunburn causes only painful reddening of the skin, but more severe cases can produce tiny fluid-filled bumps (vesicles) or larger blisters.
- Actinic keratosis
This is a tiny bump that feels like sandpaper or a small, scaly patch of sun-damaged skin that has a pink, red, yellow or brownish tint. Unlike suntan markings or sunburns, an actinic keratosis does not usually go away unless it is frozen, chemically treated or removed by a doctor. An actinic keratosis develops in areas of skin that have undergone repeated or long-term exposure to the sun’s UV light, and it is a warning sign of increased risk of skin cancer. About 10% to 15% of actinic keratoses eventually change into squamous cell cancers of the skin.
- Long-term changes in the skin’s collagen (a structural protein)
These changes include photoaging (premature aging of the skin because of sun exposure) and actinic purpura (bleeding from fragile blood vessels beneath the skin surface). In photoaging, the skin develops wrinkles and fine lines because of changes in the collagen of a deep layer of the skin called the dermis. In actinic purpura, UV radiation damages the structural collagen that supports the walls of the skin’s tiny blood vessels. Particularly in older people, this collagen damage makes blood vessels more fragile and more likely to rupture following a slight impact.
Over a lifetime, repeated episodes of sunburn and unprotected sun exposure can increase a person’s risk of malignant melanoma and other forms of skin cancer. As a rule, if you have fair skin and light eyes, you are at greater risk of sun-related skin damage and skin cancers. This is because your skin contains less of a dark pigment called melanin, which helps to protect the skin from the effects of UV radiation.Dermis Aesthetics offer skin scanning during your initial consultation to determine the right treatment for your particular needs.
The example above is the result of sun exposure through a vehicle window over a prolonged period and the devastating effect it has on the aging of the skin, the exposed side is significantly aged compared to the non exposed side.
