Sun-Damaged Skin: Photoaging, Signs, Causes & Treatment Summit Health
go to original June 13, 2023

Chances are you feel younger than what’s on your birth certificate. But do you think you look older than you are? Time spent outside over the years may have something to do with it.

Even if you’re practicing sun safety now, the damage may already be done. Years of exposure to ultraviolet (UV) radiation — whether from the sun or tanning beds — can lead to sun-damaged skin, also known as photoaging. UV rays can cause DNA changes in your skin cells, resulting in premature skin aging and an increased risk of skin cancer.

While sun-worshippers and people with lighter skin tones are more at risk for sun damage, UV rays can leave their mark on anyone. And photoaging can appear earlier than you might think. “Signs of photoaging can start as young as your teens to early 20s,” says Chelsey Gallegos, PA-C, a Physician Assistant at Summit Health Dermatology.

Common signs of sun damage

Sun-exposed areas such as your face, neck, upper chest, arms, hands, and legs are the most susceptible to photoaging. Chelsey says the most common signs of sun damage she sees include:

• Broken capillaries. These enlarged blood vessels also are called spider veins or telangiectasia. Sun exposure can break down the fibers keeping these small vessels tight, allowing them to grow larger and give your skin a reddish appearance, often on the nose and cheeks.
• Pigmentation changes. Your skin produces a brown pigment called melanin to protect your skin cells from sun damage. But sometimes the sun triggers an uneven increase in melanin production, resulting in irregular skin coloring. Freckles and age or liver spots (solar lentigines) are examples of pigmentation changes.

She adds that other photoaging signs can include:

• Wrinkles
• Uneven skin texture
• Loss of skin tone or elasticity

Cosmetic treatments for sun-damaged skin

Although you can’t completely reverse sun damage, there are treatment options that can reduce some of its visible effects. Chelsey says Summit Health offer these cosmetic procedures:

• Cosmetic botulinum toxins. This injectable treatment for wrinkles works by blocking nerve impulses to muscles, causing them to relax. Botulinum toxins are better known by their brand names, such as Botox CosmeticÒ.
• Dermal fillers. Chelsey notes that these injectable gel-like substances can be used to restore facial volume when appropriate.

Chelsey adds that treating pigmentation changes early can help in reducing premature skin aging, as can using the right skin care products. Summit Health offers consultations for guidance on a skin care routine and products that best meet patients’ needs.

Still, Chelsey says the best treatment for sun-damaged skin is prevention. “Sun protection is the most important,” she says. Not only can it prevent adding years to your appearance, but it can reduce your risk of developing skin cancer.

Sun safety tips

UV exposure is the most preventable cause of skin cancer. While sun exposure is inevitable, you and your family can take steps to enjoy the outdoors safely.

• Cover up. Wear lightweight protective clothing such as long-sleeved shirts, pants, and wide-brimmed hats. Choose sunglasses with UV protection since the sun’s rays can also damage your eyes. Wrap-around style sunglasses can prevent the sun from getting in on the sides.
• Get in the shade. The sun’s rays are the most intense between 10 a.m. and 4 p.m., so minimize your midday exposure. Do not be fooled by a cloudy day — the sun can still damage your skin.
• Use the right amount of sunscreen. Choose a broad-spectrum sunscreen with SPF 30 or higher. Apply at least 1 ounce — about a palmful’s worth — every two hours, and more often if you are sweating or getting in the water. Do not forget places like your ears and hairline. Protect your lips with sun balm.
