As people age, their skin goes through natural changes that can affect how it responds to sunlight. Many older adults assume that sun protection is less important later in life, but UV exposure continues to affect the skin at every age. Taking simple steps to protect the skin can support long-term health and help lower the risk of sun-related damage.
Skin Cancer Risk Later in Life
Skin cancer is one of the most common cancers in Canada. Rates of both diagnosis and mortality are higher in older adults compared to younger age groups. Studies show that more than half of skin cancer related deaths occur in people over the age of 65. The longer someone lives, the more cumulative UV exposure they experience, which increases the chance of developing skin cancer over time.
Most skin cancers are linked to long-term sun exposure. Both suntans and sunburns can damage the skin’s DNA, which may lead to changes in the skin’s tissues and an increased risk of cancer. Even a few significant sunburns over a lifetime can raise this risk. You can learn more about common forms of skin cancer on our skin cancer overview page.
How Skin Changes With Age
Aging affects the skin in ways that make it more vulnerable to sunlight.
Intrinsic Aging
This refers to natural changes that occur in the skin over time. The skin gradually becomes thinner and loses moisture and elasticity. These changes allow UV rays to reach deeper layers of the skin. As we age, the body’s ability to repair DNA damage also slows, which may increase the chance of abnormal cell growth.
Extrinsic Aging
This type of aging is influenced by environmental factors, including UV exposure, smoking, pollutants, and certain medical conditions. Many older adults spend more time outdoors, whether for travel, hobbies, or retirement activities like golf or gardening. Increased UV exposure can weaken immune responses in the skin and contribute to the development of skin cancer.
Contrary to older beliefs that most sun damage happens before age 18, newer research shows that sun exposure continues to accumulate throughout life. Much of it occurs after age 40, which is why ongoing protection is important at every age.
Why UV Protection Matters for Seniors
UV exposure is a leading factor in the development of skin cancer. The good news is that protection can be built into daily routines. Here are three simple steps that can help support skin health:
1. Avoid tanning beds
Tanning beds expose the skin to concentrated UV radiation and are linked to an increased risk of skin cancer.
2. Use effective sun protection
This includes seeking shade, wearing protective clothing, and using a broad spectrum sunscreen with an SPF of 30 or higher. For a simple overview of sunscreen types and what to look for, you can read our Skin Cancer 101 post.
3. Check your skin regularly
Monthly self-exams can help you notice new or changing spots. A yearly visit with a qualified medical professional is also recommended. You can learn more about what we look for during an exam on our skin screenings page.
Protecting your skin is important at every stage of life. Small daily habits can help reduce UV related damage and support healthier skin as you age.
