Does a base tan protect you from sunburn?
Getting a "base tan" before a beach vacation, often in a tanning bed, is a common habit. The idea is that a light tan will stop you from burning later. Dermatologists say this doesn't work.
What a tan actually is
A tan is your skin's response to UV damage. When UV rays damage skin cells, the skin produces more melanin pigment. In other words, the tan itself is a sign of damage, not a shield. See MedlinePlus: Tanning and FDA: The risks of tanning.
What dermatologists say
The American Academy of Dermatology: 10 surprising facts about indoor tanning calls the idea that a base tan prevents sunburn "an absolute myth": you can still burn with a base tan. Each time you tan or burn, you damage the DNA in your skin, and the more damage, the greater your skin cancer risk. The AAD also notes that indoor tanning can more than double the risk of melanoma.
Tanning products don't change this
Getting darker with tanning injections or nasal sprays doesn't make UV exposure safe either. Unapproved melanotan products also raise their own concerns, including changes in moles. See moles and melanoma and tanning beds and UV.
What actually protects you
- Broad-spectrum sunscreen, SPF 30 or higher, reapplied regularly: sunscreen guide.
- Shade, especially in the middle of the day.
- Clothing, a wide-brimmed hat and UV-blocking sunglasses.
- Checking the UV Index before you go out.
- For a tanned look, a self-tanner, combined with sunscreen: sunless tanning options.
