Know what is spf

Who needs sunscreen? Everyone under the sun. Oh, and did you know there’s no escaping—even on the cloudy days? So, let’s not add sunburn to our list of regrets when we can safely avoid this irreversible damage. What’s an easy way around that? Make a sunscreen with sufficient SPF your handbag essential.

What is SPF?

SPF stands for Sun Protection Factor. What does it measure? The SPF of a sun protection product determines the level of UVB protection it offers. SPF products are available in various levels, including SPF 15, SPF 30, SPF 50 and more. Here’s how they work:

  • SPF 15 sunscreen filters out around 93% of UVB radiation
  • SPF 30 sunscreen blocks approximately 97% of UVB radiation
  • SPF 50 sunscreen keeps out nearly 98% of UVB radiation

Think about it this way. If you use a sunscreen with SPF 50, it would take you 50 times longer to experience sunburn as compared to without sunscreen. A higher range SPF prevents more damaging UVB rays from penetrating than a lower range SPF can prevent. So, a higher SPF translates to higher sun protection and lesser skin damage.

What level of SPF do you need?

If you spend most of your time indoors and lesser time outdoors, you can safely use a sunscreen that provides an SPF 20 or lower. If you are constantly travelling and are exposed to the sun, we recommend you liberally apply a sunscreen of SPF 30 or higher. But, none of this would matter if you forget to re-apply your sunscreen every two hours. Wait, you thought you had to apply sunscreen just once? The answer is an empathetic ‘No’.

Apart from SPF, the other factors that also affect the level of protection include:

  • Your skin type
  • Frequency of sunscreen application
  • Existing weather conditions and environment
  • Amount of perspiration
  • Amount of time spent near any reflective surfaces, such as sand and water

The Section Where Your Lingering Doubts are Finally Answered

1. Does a high SPF protect against both UVA and UVB rays?

No. SPF products are meant to protect only against UVB rays. This means you will still be exposed to harmful UVA rays that cause tanning and premature aging. To ensure complete protection, prefer a broad-spectrum sunscreen.

2. Do extremely high SPF products mean higher protection?

Higher SPF products only provide marginally better protection but still keep you unsafe from UVA rays. If you correctly use a sunscreen of SPF range between 30 and 50, it can offer adequate protection. Just remember to apply and re-apply.

3. What are the things to consider while choosing a sunscreen?

  • Check for SPF
  • Ensure it is a broad-spectrum or full-spectrum sunscreen
  • Check if it’s water-resistant
  • Check if it’s formulated for your skin type

4. Is SPF 30 enough or should sunscreens of SPF 50 be preferred?

The UVB protection offered by SPF 50 and SPF 30 differs by just 1 percent. A sunscreen of any SPF is adequate if re-applied at regular intervals in adequate quantities. A higher SPF does not mean higher protection.

5. What does ‘Broad-spectrum’ mean?

Broad-spectrum in the label of any sunscreen is as important as SPF. A broad-spectrum or full-spectrum sunscreen protects against both UVB and UVA rays. Normal sunscreens do not provide protection against UVA rays. It is recommended to choose a broad-spectrum sunscreen.

6. What is the minimum SPF that should be used?

SPF 15 is the FDA's minimum recommendation for protection against skin cancer and sunburn, whereas the AAD advises using an SPF 30 or more sunscreen.

7. Is it okay to use an everyday lotion with SPF in it?

Everyday face lotions with SPF are great for your skin and provide protection against incidental sun exposure. If you are planning to spend a significant amount of time in the sun, we advise you apply a broad-spectrum sunscreen to ensure UVA and UVB protection.

8. How long does SPF 50 last?

A sunscreen's sun protection factor (SPF) stays completely effective for two hours post application. We recommend carrying your sunscreen along with you, so you can re-apply whenever necessary.
