Sun Damage | Stuart and Tequesta, FL

Sun damage refers to the injury to the skin caused by exposure to ultraviolet (UV) light. DNA damage can increase the signs of aging and the risk for certain skin cancers like melanoma, basal cell carcinoma, and squamous cell carcinoma. Exposure to ultraviolet light accumulates over one’s lifetime.

Signs of sun damage appear in areas that are constantly exposed, like the face, neck, and back of the hands. In this short term, sun exposure results in well-known sunburn and tanning of the skin. It's important to note that even tanning without a sunburn can cause damage to the skin. Sun exposure can darken freckles and worsen a condition known as melasma. The skin will age faster and will have a greater tendency to wrinkle and lose its elasticity and youthfulness. Discoloration and skin thinning are common features. Further sun damage results in things like age spots or liver spots (solar lentigines). And the more severe sun damage results in precancerous lesions like actinic keratosis and full skin cancers like basal cell carcinoma, squamous cell carcinoma, and melanoma.

The most important way to treat sun-damaged skin is to never have sun damage at all. Wearing sun protective clothing and sunblock are critical, especially with prolonged sun exposure. Areas of the body that are constantly exposed to the elements, like the face, head, neck, and back of the hands, would benefit from daily sunblock. Even small amounts of sun exposure to these areas can add up day in, day out. And even on cloudy days, a significant amount of ultraviolet light reaches through the clouds! Physical sunblocks, ones that contain zinc or titanium (many that are labeled “baby safe”), are preferred over chemical sunblocks. This is because chemical sunblocks can irritate the skin and be absorbed into the bloodstream.

The supplement Polypodium Leucotomos (Heliocare ®) has been shown to help prevent some damage with sun exposure. However, this should not be used as a substitute for sun protection. Retinoid-containing creams, which are also used for the treatment of acne, can also help to reverse some of the signs of aging related to sun-damaged skin. The chemotherapy cream 5-fluorouracil, used for treating precancerous lesions, targets damaged skin cells and can help improve sun-damaged skin. Chemical peels can help rejuvenate the skin and stimulate cell growth. Neurotoxins like Botox ® and fillers can reduce wrinkles and provide a more youthful fullness.

Are tanning beds a safer alternative to sun exposure?
No, tanning beds are not a safer alternative to sun exposure. Both emit harmful UV radiation that can lead to skin damage and increase your risk of skin cancer. It's a misconception that tanning beds are a "safer" way to achieve a tan; they are just as risky.

Does skin type affect sun damage risk?
Yes, individuals with fair skin, light eyes, and light hair are generally more susceptible to sun damage. However, people of all skin types can experience sun damage and should take protective measures.

Is occasional sun exposure without sunscreen OK?
While brief sun exposure can help with vitamin D production, it's still essential to protect your skin. No amount of unprotected sun exposure is considered entirely safe, as it can lead to skin damage and increase the risk of skin cancer.
