The Dangers of a Base Tan: A Dermatologist’s Perspective
As dermatologists, we cannot stress enough the importance of protecting our skin from harmful UV rays. Whether from the sun or a tanning bed, tanning can have severe consequences for your skin’s health. In this blog post, we’ll be answering some commonly asked questions about tanning and providing tips on how to keep your skin safe and healthy.
Q: What is a base tan? And why do some people think that it’s okay?
A base tan refers to the practice of getting a tan before going out in the sun for an extended period. The idea is that the base tan will offer some protection against sunburn and skin damage. However, this is a dangerous misconception for two main reasons. First, a base tan DOES NOT prevent your skin from burning. Secondly, the truth is that any amount of indoor or outdoor tanning can cause skin damage, including premature aging, wrinkles, and an increased risk of skin cancer.
Q: What happens to skin when it tans?
When skin tans, it is actually a sign of damage. The Skin Cancer Foundation explains how exposure to ultraviolet (UV) radiation results in tanning, which occurs as a protective response to genetic damage to the outermost layer of skin cells. The skin produces more melanin, a pigment that protects the skin from UV damage. This process is the skin’s attempt to protect itself from further damage. However, the damage has already been done, and prolonged exposure to UV rays can lead to long-term skin damage.
Q: What do UV rays do to the skin?
UV rays can break down collagen and elastin in the skin, leading to premature aging, wrinkles, and other signs of skin damage. In addition, UV rays can damage the skin’s DNA, leading to mutations that can cause skin cancer. UV exposure damage is cumulative, increasing your skin cancer risk over time. Your body will attempt to repair DNA damage in skin cells caused by UV radiation, but the damage it cannot repair builds up over time. This can trigger mutations that cause skin cells to multiply rapidly, developing benign or malignant growths.
Q: Can tanning also harm my eyes?
Yes, exposure to UV rays can also harm the eyes. It can cause photokeratitis, which is like a sunburn of the cornea. Prolonged exposure can lead to cataracts, macular degeneration, and other eye conditions. So it’s essential to wear sunglasses that block out UV radiation to protect your eyes.
Q: What about tanning beds?
Tanning beds are not a safe alternative to natural sunlight. They emit high levels of UV radiation, leading to skin damage and an increased risk of skin cancer. In fact, using a tanning bed before age 35 increases the risk of melanoma by 75%. They can also cause serious damage in other ways, such as first and second-degree burns and eye damage. To learn some great information on indoor tanning, the American Academy of Dermatology talks about it here.
Q: What are some tanning myths that people should stop believing?
- One common myth is that getting a base tan will protect your skin from sunburn and skin damage. As I mentioned earlier, any amount of tanning can cause skin damage, and a base tan is not a safe alternative to sunscreen, nor can it prevent your skin from getting sunburned.
- Indoor tanning is safer than outdoor tanning. In reality, tanning beds emit high levels of UV radiation, which can be even more damaging than natural sunlight.
- Tanning beds are a good way to get Vitamin D for your body. However, tanning beds use bulbs that emit UVA light when the body needs UVB to produce Vitamin D.
Q: What safe alternatives to sun tanning will give me that summer glow?
Several safe alternatives to sun tanning can give you a much-desired glow. Self-tanning products, such as lotions, sprays, and mousse, can give you a natural-looking tan without exposing your skin to harmful UV rays. Bronzing powders and creams can also give your skin a sun-kissed glow.
Q: What are five tips to protect my skin from harmful rays?
- Wear sunscreen with an SPF of at least 30 daily, even on cloudy days.
- Wear protective clothing, such as hats and long-sleeved shirts, when spending time in the sun.
- Seek shade during peak sun hours, typically between 10 a.m. and 4 p.m.
- Avoid tanning beds and other sources of artificial UV radiation.
- Get regular skin exams from a dermatologist to monitor for any signs of skin cancer.
