Introduction:
Sun Protection Factor, commonly known as SPF, is a crucial metric that determines the efficacy of a sunscreen. SPF 70 represents a robust level of protection, indicating that the sunscreen can block approximately 98% of UVB rays, the primary culprits behind sunburns and skin damage. While SPF 30 is widely recommended, SPF 70 takes sun protection to a new level, offering enhanced defence against the sun’s harmful effects.
Benefits of SPF 70 Sunblock for All Skin Types:
1. High-Level Protection:
SPF 70 offers an advanced level of protection, making it suitable for individuals with fair and sensitive skin or those prone to sunburn. Its ability to block 98% of UVB rays provides an extra layer of defence, especially during prolonged sun exposure.
2. Defence Against Premature Ageing:
UVA rays are a significant contributor to premature ageing, leading to fine lines, wrinkles,
and a loss of skin elasticity. SPF 70 Sunblock helps thwart these ageing effects by preventing UVA penetration, preserving the skin’s youthful appearance.
3. Lower Risk of Skin Cancer:
The dual protection of SPF 70 against UVA and UVB rays reduces the risk of skin cancer. Prolonged sun exposure without adequate protection is a major risk factor for skin cancer, making a high SPF sunscreen an essential tool in skin cancer prevention.
4. Versatility for All Skin Types:
Whether you have fair, medium, or dark skin, SPF 70 Sunblock caters to all skin types. Its universal efficacy ensures that individuals with varying skin tones can benefit from the same high level of sun protection.
5. Suitable for Outdoor Activities:
For those engaged in outdoor activities or sports, where sun exposure is prolonged, SPF 70 Sunblock provides reliable protection. It withstands sweat and water, offering peace of mind to individuals who lead an active lifestyle.
6. Enhanced Protection for Photosensitive Skin:
Some individuals have skin conditions or medications that make their skin more sensitive to sunlight. SPF 70 Sunblock provides an added layer of defence for those with photosensitive skin, reducing the risk of adverse reactions.
7. Defence Against Hyperpigmentation:
Individuals prone to hyperpigmentation or those with existing dark spots benefit from the preventive qualities of SPF 70. By blocking UV rays, it helps prevent further pigmentation and contributes to a more even skin tone.
Proper Application of SPF 70 Sunblock:
Achieving optimal sun protection involves more than just selecting a high SPF.
Proper application is paramount to harnessing the full benefits of SPF 70 Sunblock:
1. Apply Generously:
Use a liberal amount of sunscreen to cover all exposed skin. The recommended amount is about one ounce (30 ml) for an average-sized adult body.
2. Reapply Regularly:
Sunscreen effectiveness diminishes over time, especially with factors like sweating or water exposure. Reapply SPF 70 Sunblock every two hours or more frequently if swimming or sweating profusely.
3. Don’t Forget High-Risk Areas:
Pay attention to often overlooked areas, such as the tops of ears, neck, hands, and the scalp if hair is thinning. These areas are susceptible to sun damage and should be adequately protected.
4. Allow Time to Absorb:
Apply sunscreen at least 15-30 minutes before sun exposure to allow it to absorb into the skin. This ensures maximum effectiveness once you step into the sun.
5. Layer with Other Sun Protection Measures:
Sunscreen should be a part of a comprehensive sun protection routine. Combine it with other measures such as seeking shade, wearing protective clothing, and using sunglasses to shield your eyes.
Frequently Asked Questions (FAQs)
1: What does SPF 70 mean, and how does it differ from lower SPFs?
SPF 70 stands for Sun Protection Factor 70, indicating the level of protection a sunscreen provides against UVB rays. SPF 70 blocks approximately 98% of UVB rays, offering higher protection than lower SPFs, such as SPF 30. This extra protection is beneficial for individuals with fair or sensitive skin or those who spend extended periods in the sun.
2: Why is it important for a sunscreen to be labelled “Broad Spectrum”?
Sunscreens labelled as “Broad Spectrum” provide protection against both UVA and UVB rays. UVB rays cause sunburn, while UVA rays penetrate deeper, contributing to premature ageing and an increased risk of skin cancer. A Broad Spectrum SPF 70 Sunblock ensures comprehensive defence against both types of harmful UV rays.
