We often associate a glowing complexion with good health, but skin colour obtained from being in the sun actually accelerates the effects of aging and increases your risk for developing skin cancer later on.
Sun exposure causes most of the skin changes that we think of as a normal part of aging. Over time, the sun's ultraviolet (UV) light damages the elastin fibres in the skin. When these fibres break down, the skin begins to sag, stretch, and lose its ability to go back into place after stretching. The skin also bruises and tears more easily - taking longer to heal. So while sun damage to the skin may not be apparent when you're young, it will definitely show later in life.
How Does the Sun Change My Skin?
Exposure to the sun causes:
- Pre-cancerous (actinic keratosis) and cancerous (basal cell carcinoma, squamous cell carcinoma and melanoma) skin lesions - due to decreases in the skin's immune function
- Benign tumors
- Fine and coarse wrinkles
- Telangiectasia - vasodilation of the blood capillaries in the skin
- Elastosis - the destruction of the elastic and collagen tissue (causing lines, wrinkles and sagging skin)
Skin cancer is the most prevalent form of all cancers in New Zealand and the number of cases continues to rise. It is the uncontrolled growth of abnormal skin cells. This rapid growth results in tumors, which are either benign (non-cancerous) or malignant (cancerous).
There are three main types of skin cancer:
- basal cell carcinoma
- squamous cell carcinoma
Ultraviolet (UV) radiation from the sun is the number-one cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the same risk as exposure during the summertime because UVA rays are present in daylight.
Cumulative sun exposure causes mainly basal cell and squamous cell skin cancer, while episodes of severe sunburns, usually before age 18, can contribute to developing melanoma.
As Beauty therapists we all understand how important it is to avoid the sunburn and protect the skin from dangerous UV exposure. We educate our clients to avoid sunburn and the importance of using sun protection, every day. We understand that UV radiation is the major contributor of skin ageing.
For the first time, this incredible video by Thomas Leveritt shows us what the sun actually does to the skin; and how important it is to protect it with a good quality sunblock.
