Debunking 10 sunscreen myths: Protecting your skin the right way

New Delhi: As the scorching summer months arrive, the significance of sunscreen in safeguarding our skin from the harmful effects of the sun’s rays becomes paramount. Sunscreen is a vital tool in preventing sunburn, skin damage, premature aging, and even skin cancer. However, amidst the abundance of information available, various myths and misconceptions surrounding sunscreen have emerged, potentially hindering us from using this essential product effectively.

Let’s delve into the details and separate fact from fiction to debunk these common sunscreen misconceptions and ensure your skin stays protected.

1. All sunscreen is the same:

While the ultimate goal is sun protection, different sunscreens work based on their ingredients and protection levels, there are two broad categories of sunscreen: chemical and physical. Chemical sunscreens contain avobenzone and oxybenzone, absorbing the sun’s rays and converting them to heat. On the other hand, physical sunscreens, also known as mineral sunscreens, use ingredients like zinc oxide and titanium oxide to reflect the rays. Understanding their differences can help you choose the right one for your needs and skin type.

2. Higher SPFs are better:

Contrary to the belief that higher SPF numbers offer superior protection, the difference between SPF 50 and SPF 100 is marginal. SPF 50 blocks about 98% of UV rays, while SPF 100 only blocks approximately 99%. No sunscreen can provide complete protection, so it’s crucial to reapply regularly, especially after swimming or sweating. The American Academy of Dermatology recommends using a broad-spectrum, SPF 30 or higher, and reapplying every two hours.

3. Makeup with sunscreen is enough:

While makeup or moisturizers with SPF add some protection, they aren’t a substitute for sunscreen. The effectiveness of SPF in makeup depends on the thickness of its application, which may not match the level of protection indicated on the product. Properly applying sunscreen before makeup is essential for optimal sun protection.

4. Waterproof sunscreen doesn’t need reapplication:

Despite the label, waterproof sunscreen eventually washes off due to water and sweat. To maintain protection, it’s essential to reapply sunscreen every two hours, regardless of water exposure. Waiting for 10 to 15 minutes after applying sunscreen before getting in the water allows it to bond with your skin properly.

5. Darker skin doesn’t need sunscreen:

While melanin in darker skin offers some natural protection, it doesn’t prevent skin damage and cancer risks. Everyone, regardless of skin tone, should wear sunscreen to protect their skin from harmful UV rays. Studies have shown that people with darker skin may have lower survival rates for skin cancer due to underdiagnosis, emphasizing the importance of sunscreen use for everyone.

6. Sunscreen is only needed on sunny days:

Clouds don’t entirely block UV rays, and over 90% of them penetrate clouds. Even on cloudy days, sunscreen remains vital for skin protection, especially in regions with high UV index.

7. Sunscreen causes vitamin D deficiency:

While sunscreen blocks most UVB rays responsible for vitamin D production, it allows a small percentage of them through. This is generally sufficient for the body to produce the necessary vitamin D. Balancing sun exposure with sunscreen application ensures both protection and vitamin D synthesis.

8. Safe base tans exist:

A base tan doesn’t protect the skin from further sun damage, and UV radiation from tanning beds increases the risk of skin cancer. Tanning, whether from natural sunlight or tanning beds, is a sign of skin damage and should be avoided.

9. Sunscreen is harmful to the skin:

Some concerns have arisen around certain chemical sunscreen ingredients, but further research is needed to conclude their effects on human health. Opting for sunscreens formulated for sensitive skin can minimize any potential irritation or allergic reactions.

10. Sunscreen doesn’t expire:

Sunscreen does have an expiration date, and using expired products can lead to reduced effectiveness. Pay attention to the expiration date and store sunscreen away from direct sunlight or excessive heat to ensure optimal protection.

To ensure proper sun protection, incorporate sunscreen into your daily routine and reapply it every two hours when outdoors. Protecting your skin is vital to prevent sun damage, sunburn, and reduce the risk of skin cancer. Stay informed and make sunscreen a non-negotiable part of your skincare regimen this summer.
