Know your SPF, its numbers and their importance

While it’s no news that the sunscreens rich in SPF aka sun protecting factor, can shield your skin from the harmful UVB rays that cause skin burn and might cause skin cancer, many of us live in the shadow when it comes to understanding fully well how the SPF and its numbers work. Let’s look at some facts on sunscreens and SPF to better understand their usage and how they work:

  1. SPF is the measure of how well your sunscreen can protect your skin from the UVB rays.
  2. SPF says nothing about how well your sunscreen protects your skin from UVA rays that also causes skin damage.
  3. Dermatologists and experts recommend using a minimum of 15 SPF or 30 SPF while claiming that a higher SPF does not provide any more protection than these.
  4. We all have different skin types that react to sun exposure differently. If your skin normally burns after ten minutes of exposure, a 15 SPF sunscreen will provide protection till 150 minutes in the sun, and will allow you to remain in the sun in that amount of time without burning. 
  5. If you have applied a 15 SPF sunscreen then its recommended that you reapply after every two hours for best results.
  6. It is highly recommended that you use the sunscreen every time you step out, even when it’s cloudy as 80 percent of the UV rays penetrate your skin. You need to apply a water-resistant before stepping into the pool or before going for a swim and reapply after coming out of the water. 
  7. The efficacy of the sunscreen depends on various factors such as the intensity of the sun rays, your skin type and amount of sunscreen used. It’s recommended that you apply a minimum of one ounce all over your body before stepping out and use the same amount to reapply after two hours.
  8. SPF 30 blocks half the radiation that an SPF 15 allows to penetrate through your skin.
  9. It’s a myth that sunscreens with higher than 30 SPF provide better sun protection. What you should be looking at before purchasing sunscreen is whether it provides broad-spectrum protection or not, meaning it should provide UVA protection of at least one-third of the UVB protection. Most of the high SPF sunscreens fail to meet this criterion. 

Alyuva’s sunscreen with 30 SPF other than providing broad-spectrum protection is enriched with hundred times washed ghee or clarified butter, a natural hydrating and moisturizing agent that replenished and repairs your skin, down to its all of the seven layers. It sits light on your skin and has a natural earthy fragrance to it. Apply it twice a day for best results and don’t forget to carry it when you step out.
