What is the main advantage of spray tanning over tanning beds?

The main advantage of spray tanning over tanning beds is that it provides instant color without UV exposure. This is significant because UV exposure can lead to skin damage and increase the risk of skin cancer. Spray tanning utilizes a solution that contains dihydroxyacetone (DHA), which reacts with the amino acids in the skin to give it a bronzed appearance almost immediately after application. This method allows individuals to achieve a tanned look without subjecting their skin to harmful UV rays found in tanning beds, making it a safer alternative for those concerned about skin health.

The other options do not accurately address the primary benefit of spray tanning. While the longevity of a spray tan can vary depending on skin type and maintenance, it's not universally true that spray tans outlast tanning beds. Additionally, spray tanning can often be more expensive due to the cost of the solutions and professional application compared to some tanning beds. Lastly, the application of spray tanning typically requires less time than lying in a tanning bed, where sessions can last longer depending on individual tanning goals.
