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.
