No, SPF 70 is not too much for the face in terms of protection; however, there are important factors to consider.
Understanding Sunscreen and SPF
Sun Protection Factor (SPF) measures a sunscreen's ability to filter UVB rays, which are the primary cause of sunburn. SPF 70 indicates that the sunscreen blocks approximately 98% of UVB rays. While a higher SPF offers slightly more protection, the difference between SPF 30 and SPF 70 is not as dramatic as it might seem.
Considerations with High SPF
Here are key points to consider when using high SPF sunscreen:
- Effectiveness: The effectiveness of any sunscreen, including SPF 70, depends on applying it liberally.
- Most people do not use enough sunscreen, which significantly reduces the protection level they receive, according to the reference.
- A general guideline is to use about a half teaspoon for the face and neck.
- Application: Regular reapplication is crucial, especially after swimming, sweating, or towel drying.
- Type of Sunscreen: There are two primary types of sunscreens:
- Mineral sunscreens (containing zinc oxide or titanium dioxide) physically block UV rays.
- Chemical sunscreens absorb UV rays.
- Choose the type that best suits your skin and needs.
- Skin Sensitivity: While high SPF sunscreens are not inherently bad for the skin, some formulations may contain ingredients that could cause irritation. If you have sensitive skin, look for fragrance-free and hypoallergenic options.
Why People Might Think High SPF is "Too Much"
The idea that high SPF is "too much" can stem from:
- False Sense of Security: A higher SPF might tempt people to apply less often or not as liberally, leading to inadequate protection.
- Cost: Higher SPF products are often more expensive, and some may think it's unnecessary to pay the extra when proper application of a lower SPF sunscreen would be just as effective.
- Texture/Feel: Some higher SPF sunscreens can be thicker or leave a white cast on the skin, which can make them less pleasant to use, which might cause some individuals to choose a lower SPF.
Key Takeaway
The important thing is to choose a sunscreen you will use correctly and consistently. High SPF sunscreens, like SPF 70, can be beneficial as long as you apply the correct amount and reapply as needed.
