What is one of the most common myths about tanning?

The belief that a base tan prevents sunburn is a common myth and reflects a misunderstanding of how skin damage works. Many people think that being tanned offers a protective barrier against sunburn, but in reality, a base tan provides minimal protection, roughly equivalent to a sunscreen with an SPF of about 3 or 4. This is insufficient compared to the higher SPF products recommended for adequate sun protection. Moreover, any exposure to UV radiation, whether from the sun or tanning beds, can cause cumulative damage to the skin and increase the risk of skin cancer over time. Therefore, relying on a base tan can lead to greater sun exposure and, ultimately, an increased risk of skin damage rather than providing the protection that individuals believe it does.
