Sunshine = Ultraviolet (UV) Light and Radiation
Sun exposure involves more than just feeling the warmth of sunlight, it also means exposure to ultraviolet (UV) light and radiation. The sun emits UV radiation through UVA, UVB, and UVC rays. While UVC rays are absorbed by the Earth’s atmosphere and do not reach us, UVA and UVB rays penetrate the atmosphere and impact our skin.
UVA rays penetrate deep into the skin, leading to premature aging and wrinkling. They can also contribute to skin cancer by damaging skin cells over time. UVB rays, while less penetrating, are primarily responsible for sunburn and direct DNA damage in skin cells, which can also result in skin cancer.
Ultraviolet (UV) radiation damages the skin by penetrating its layers, causing immediate effects like sunburn and long-term issues such as premature aging and skin cancer. UVB rays damage the DNA in skin cells, while UVA rays penetrate deeper, leading to wrinkles and increased cancer risk over time.
UV radiation is invisible and can affect the skin even on cloudy days, making consistent sun protection essential. Prolonged exposure to UV radiation can cause immediate effects like sunburn and long-term consequences such as photoaging and increased risk of skin cancers. Therefore, understanding and mitigating UV exposure is critical for maintaining skin health and preventing harmful effects.
Skin cancer is the most common form of cancer in the U.S., and the National Cancer Institute estimates 100,640 new cases of skin melanomas and 8,290 so far in 2024. Sunscreen is one way to protect your skin from all these issues.
Causes of Sun Skin Issues
How does sunburn occur?
Melanin gives skin its color. Exposure to ultraviolet (UV) light causes skin to produce more melanin as a form of protection. Sunburn occurs when the skin is overexposed to ultraviolet (UV) radiation, primarily UVB rays. This excess UV exposure damages the DNA in skin cells, triggering an inflammatory response that results in redness, pain, and swelling. Over time, repeated sunburns increase the risk of skin cancer and premature aging.
How does skin aging by sun exposure occur? (aka, photoaging)
Photoaging occurs when prolonged sun exposure damages the skin’s structural components, primarily collagen and elastin, through UVA and UVB radiation. This damage leads to wrinkles, loss of skin elasticity, and uneven pigmentation.
UV radiation generates free radicals, which further harm skin cells and accelerate aging. Consistent sun protection can significantly reduce the risk of photoaging and maintain healthier, more youthful skin. UV rays penetrate deep into the skin, and prolonged exposure damages the collagen fibers. This damage produces increased abnormal elastin, and this abnormal elastin produces enzymes called metalloproteases.
These enzymes, which rebuild damaged collagen, often malfunction and degrade the collagen, producing incorrectly rebuilt skin. if this process repeats, the incorrectly built skin forms wrinkles, and the depleted collagen results in leathery skin.
How does sun exposure cause skin cancer?
Sun exposure causes skin cancer primarily through the damaging effects of ultraviolet (UV) radiation on the DNA of skin cells. Prolonged exposure to UV radiation can damage the DNA in skin cells.
UVB rays directly harm the DNA, leading to mutations that can result in uncontrolled cell growth. UVA rays penetrate deeper, generating free radicals that also damage DNA.
Over time, this DNA damage accumulates, impairing the skin’s ability to repair itself and potentially leading to the development of skin cancers such as melanoma, basal cell carcinoma, and squamous cell carcinoma. If enough DNA damage occurs, it can cause skin cells to grow uncontrollably, which can lead to skin cancer, and skin cancer can grow through the layers of the skin and metastasize to other organs.
Regular sun protection can help reduce the risk of skin cancer by minimizing UV exposure.
Protecting Your Skin with Sunscreen
Sun protection factor (SPF)
(SPF) is a number that measures the amount of UV energy required to produce sunburn on protected skin relative to the amount of UV energy required to produce sunburn on unprotected skin. As the SPF value increases, sunburn protection increases.
Only broad-spectrum sunscreens with a sun protection factor (SPF) of at least 15 protects the skin from the described issues, even on cloudy days, because UV rays can pass through clouds. SPF is not a measure of time for UV exposure or protection, that’s a popular misconception!
FDA Evaluations of Sunscreen Products
The FDA evaluates sunscreen products to ensure their safety and effectiveness through a series of rigorous tests and regulatory requirements. Here’s an overview of the key steps involved:
- Ingredient Review:
- The FDA reviews the active ingredients in sunscreen products to determine if they are generally recognized as safe and effective (GRASE). This involves evaluating scientific data on their safety,
efficacy, and potential health risks.
- The FDA reviews the active ingredients in sunscreen products to determine if they are generally recognized as safe and effective (GRASE). This involves evaluating scientific data on their safety,
- Testing for Broad-Spectrum Protection:
- Sunscreens must undergo testing to demonstrate their ability to protect against both UVA and UVB rays. Products labeled as “broad-spectrum” must provide proportional protection against both types of radiation.
- SPF Testing:
- The Sun Protection Factor (SPF) value is determined through specific testing protocols. This involves applying sunscreen to the skin of human subjects and measuring the amount of UV radiation required
to produce sunburn compared to unprotected skin.
- The Sun Protection Factor (SPF) value is determined through specific testing protocols. This involves applying sunscreen to the skin of human subjects and measuring the amount of UV radiation required
- Water Resistance Testing:
- For sunscreens labeled as “water-resistant,” manufacturers must conduct tests to confirm the product’s effectiveness after water exposure. The label must indicate the duration of water resistance (either 40 or 80 minutes).
- Labeling Requirements:
- The FDA mandates specific labeling requirements to ensure consumers can easily understand the level of protection a sunscreen provides. This includes the SPF value, broad-spectrum status, water resistance, and usage instructions.
- Adverse Event Reporting:
- Manufacturers are required to report any adverse events or side effects related to sunscreen use. The FDA monitors these reports to identify any potential safety concerns.
These comprehensive evaluations help ensure that sunscreen products are both safe for consumers and effective in protecting against the harmful effects of UV radiation.
Get Your Protection On!
Protecting your skin with sunscreen is essential to prevent sunburn, premature aging, and skin cancer. For higher protection, use an SPF 30-broad spectrum, water-resistant sunscreen at least 30 minutes before sun exposure and reapply every two hours.
For high-risk individuals, check NOAA’s UV index forecast before long days of sun exposure, which predicts the potential for skin-damaging UV radiation. Now, here are some tips for how you should apply sunscreen:
- Apply sunscreen 15 minutes before sun exposure, especially if you’re going to be getting wet.
- Apply sunscreen liberally to all uncovered skin, especially the nose, ears, neck, hands, feet, and lips.
- Reapply sunscreen every two hours, and more frequently if swimming or sweating. Note, however:
- No sunscreen is waterproof. Check instructions for information about your sunscreen’s water resistance and reapplication.
- Protect marine life by using a chemical-free, environmentally friendly sunscreen.
- If you don’t have much hair, apply sunscreen to the top of your head.
Only sunscreens in lotion, cream, stick, gel, oil, butter, paste, spray, and powder dosage forms can be legally marketed. Other dosage forms, such as wipes, towelettes, body washes, and shampoos, cannot be legally marketed. Spray sunscreens can be flammable.

against harmful UV radiation. No sunscreen completely blocks UV radiation. Here are
some useful reminders:
- Wear Protective Clothing: Opt for long-sleeved shirts, pants, and wide-brimmed hats to cover as much skin as possible. Clothes with a high Ultraviolet Protection Factor (UPF) provide added protection. Especially wear a hat if you don’t have much hair.
- Seek Shade: Avoid direct sunlight, especially between 10:00 a.m. and 4:00 p.m. when UV rays are strongest. Use umbrellas, canopies, or trees for shade.
- Use Sunglasses: Protect your eyes and the surrounding skin with sunglasses that block 100% of UVA and UVB rays.
- Avoid Tanning Beds: Tanning beds expose you to harmful UV radiation, increasing the risk of skin cancer and premature aging.
- Check UV Index: Monitor the UV index in your area to understand the daily risk level and plan your sun protection accordingly.
- Reapply Sunscreen: Apply sunscreen 15 minutes before sun exposure and reapply every two hours, or immediately after swimming, sweating, or towel drying.
- Limit Time in the Sun: especially between 10:00 a.m. and 2:00 p.m. when the UV rays are the most intense.
By combining these methods with regular sunscreen use, you can significantly reduce your risk of sun damage and maintain healthier skin.
