Sunscreen protects your skin, but myths often blur facts. Dermatologists play a key role in guiding effective sun care, ensuring you shield against damage and maintain healthy, radiant skin.
Stepping out in the sun can feel liberating, but without sunscreen, it’s like walking a tightrope without a safety net. While sunscreen has become a buzzword in skincare routines, myths surrounding its use often leave people perplexed. Is SPF 50 really better than SPF 30? Does sunscreen block vitamin D absorption? This blog will bust the myths, uncover the facts, and help you understand why sunscreen is your skin’s best friend.
Why Is Sunscreen Important?
Sunscreen isn’t just a beach essential; it’s your daily armour against harmful UV rays. Ultraviolet radiation from the sun can cause skin damage, premature ageing, and even skin cancer. Protecting your skin with a layer of sunscreen is as vital as brushing your teeth or drinking water. However, misconceptions can keep you from making the right choices.
Let’s dive into five common myths about sunscreen and set the record straight with facts.
Myth 1: You Don’t Need Sunscreen on Cloudy Days
Fact: Up to 80% of the sun’s UV rays penetrate clouds, which means your skin is exposed even on overcast days. Skipping sunscreen because it’s cloudy puts your skin at risk of damage without you even realising it. Dermatologists emphasise applying sunscreen daily, regardless of the weather.

Myth 2: Dark Skin Tones Don’t Need Sunscreen
Fact: While melanin offers some natural protection, it doesn’t make you immune to UV damage. People with darker skin tones are still vulnerable to sunburn, hyperpigmentation, and even melanoma, though at lower rates. Experts recommend using a broad-spectrum sunscreen with SPF 30 or higher for all skin types. If you’re unsure about the right product, consult a dermatologist for tailored guidance.
Myth 3: Higher SPF Means You Don’t Need to Reapply
Fact: Sunscreen isn’t a one-and-done solution, regardless of its SPF. While a higher SPF provides more protection, no sunscreen lasts all day. Experts recommend reapplying sunscreen every two hours, especially if you’re sweating or swimming. A broad-spectrum sunscreen with SPF 30 blocks about 97% of UVB rays, and SPF 50 blocks around 98%. The difference isn’t drastic, so focus on consistent application rather than obsessing over SPF numbers.
Myth 4: Sunscreen Prevents Vitamin D Absorption
Fact: The fear that sunscreen leads to vitamin D deficiency is largely unfounded. While sunscreen does reduce UVB absorption, it doesn’t block it entirely. You can still produce sufficient vitamin D while wearing sunscreen. For those concerned, small dietary adjustments or supplements can help maintain vitamin D levels. Your dermatologist can guide you on striking a balance between sun protection and vitamin D intake.
Myth 5: Sunscreen Is Only for Outdoor Use
Fact: Indoor settings aren’t entirely safe from UV rays. UVA rays can penetrate glass windows, exposing your skin to damage even while driving or sitting by a sunny window. Apply sunscreen daily, whether you’re heading outdoors or working from home. For indoor days, lightweight sunscreens with added hydration can work wonders.
Sunscreen Tips from Dermatologists
To maximise your sunscreen’s effectiveness, follow these expert-approved tips:
- A nickel-sized amount is ideal for your face, and a shot glass is enough for your body.
- Sunscreen needs about 15-30 minutes to create a protective barrier.
- Cover often-forgotten spots like your ears, neck, and the back of your hands.
- Using expired sunscreen can reduce its effectiveness and leave your skin vulnerable.
- Use hats, sunglasses, and protective clothing for added defence against UV rays.
How to Choose the Right Sunscreen?
As there are so many options for sunscreen on the market, it can be tough to know which one to choose. Consider these factors:
- SPF Level: For most people SPF 30 is fine, but if you have sensitive or fair skin, a higher SPF might be required.
- Broad-spectrum Protection: Try finding products that protect against both UVB and UVA rays.
- Skin Type: For oily skin, choose gel-based sunscreens, for dry skin, choose cream-based sunscreens, and for sensitive skin, choose mineral sunscreens.
Conclusion
With the knowledge to debunk these common myths, you can make decisions about how to protect your skin from harm. Remember that the best way to protect yourself from the sun is to use sunscreen consistently, apply it properly, and have regular skin care checkups.
