  • SPF stands for "sun protection factor" and measures protection from UVB rays.
  • SPF 15 allows 7% of UV rays, SPF 30 allows 3%, and SPF 50 allows 2% into the skin.
  • We carefully designed Smart Screen SPF 22 to offer optimal protection for safe tanning.
  • Use Base Tan, Smart Screen, and Over Exposed for healthy, glowing skin.

Knowledge is the key to making informed decisions, especially when it comes to taking care of your skin. So, let's dive into the world of SPF and unravel the secrets of sun protection!

What is "SPF" and What Does It Stand For?

SPF stands for "sun protection factor," and it measures the level of protection a sunscreen offers against the sun's harmful UVB rays. This factor is a representation of how long your skin will remain protected from these rays and prevent sunburn when you use the product correctly, compared to the time it would take for your skin to burn without any protection at all.

SPF 15 vs. 30 vs. 50: Decoding the Difference

You might have come across charts that display SPF ratings, like this one:

While these charts hold true, they only reveal part of the story. When it comes to sun protection, it's not just about blocking a certain percentage of UV rays; it's about controlling the amount that penetrates your skin.

Consider this:

  • SPF 15 allows approximately 7% of UV rays to enter the skin.
  • SPF 30 allows around 3% of UV rays to penetrate the skin.
  • SPF 50 only permits about 2% of UV rays to reach the skin.

Though the difference may not seem huge, upgrading from SPF 15 to SPF 30 actually offers a 50% improvement in protection. It's why dermatologists often recommend using sunscreen with SPF 30 to 50 during extended sun exposure for optimal safeguarding.

Why Tropic Labs' Smart Screen SPF 22?

You might wonder why we chose SPF 22 for our Smart Screen. Ultimately, the effectiveness of sunscreen lies not only in its SPF value but also in how consistently and adequately it is used. In our rigorous testing, SPF 22 proved to strike the perfect balance between preventing sunburn and allowing your skin to tan safely.

We cannot stress enough the importance of reapplying sunscreen regularly, seeking shade during peak hours, and wearing protective clothing and hats as part of your sun safety routine. Responsible tanning involves not only using Smart Screen during prolonged sun exposure but also preparing your skin with the right melanin-boosting ingredients found in Base Tan and restoring your skin with Over Exposed after sun exposure to maintain a healthy and radiant glow.
