As a senior dermatologist, I have encountered numerous myths surrounding sunscreens. Many individuals hold misconceptions that can lead to inadequate UV protection, increasing their risk of skin damage and skin cancer. This article busts the 10 most common myths so that you can make informed decisions about your skin’s health.
Myth 1: Sunscreen is only necessary on sunny days
Fact: UV rays can penetrate through clouds and still cause skin damage even on overcast days. UV radiation is consistent, irrespective of weather conditions. Wearing sunscreen should be a part of your daily routine throughout the year. In fact, water and snow sports and holidays sun is most radiant and sun protection is most needed.
Myth 2: Darker skin tones don’t need sunscreen
Fact: While it is true that darker skin contains more melanin, which offers some natural protection from skin cancer, it is still susceptible to UV damage. Everyone, regardless of their skin tone, is at risk for skin cancer and premature ageing, so using sunscreen is crucial for all skin types.
Myth 3: Sunscreen is waterproof and lasts all day
Fact: No sunscreen is entirely waterproof. Many labels may indicate “water-resistant” for 40 to 80 minutes. Reapply every two hours, especially if you are swimming or sweating. This simple tip is vital for effective sun protection.
Myth 4: Higher SPF means better protection
Fact: While higher SPF does provide more protection, the difference diminishes beyond SPF 30. SPF 30 filters about 97 per cent of UVB rays, whereas SPF 50 blocks about 98 per cent. It’s essential to remember that sufficient application and frequent reapplication are more crucial than simply choosing the highest SPF.
Myth 5: Sunscreen doesn’t work if applied with makeup
Fact: Sunscreen can be effective even when layered under makeup, but many makeup products do not provide adequate protection. Special formulations and setting sprays with SPF can enhance protection. Look for makeup with added SPF for extra defence.
Myth 6: Sunscreen can cause skin problems
Fact: Some individuals may experience irritation or allergic reactions to specific ingredients in sunscreens. However, this is not universal. There are hypoallergenic and mineral-based options for sensitive skin. Explore various formulations to find one that suits their skin type.
Myth 7: You don’t need sunscreen if you have a tan
Fact: A tan indicates that your skin has already been damaged. Tanned skin does not provide sufficient protection against UV rays. Sunscreen should be applied regularly to prevent further damage. Also, do note that sunscreen doesn’t make you fairer, not unless it’s a hybrid sunscreen with active ingredients, which are rare in the Indian market currently.
Myth 8: Sunscreen can be applied once for all-day protection
Fact: Sunscreen needs reapplication at least every two hours and immediately after swimming or sweating. Sunscreen’s effectiveness diminishes over time, and diligent reapplication is essential for continued protection.
Myth 9: Sunscreen is only for the beach or outdoor activities
Fact: UV rays can penetrate windows indoors, leading to potential skin damage. Incorporate sunscreen into your daily skincare routine, especially if you spend considerable time near windows.
Myth 10: Natural or homemade sunscreens are just as effective as commercial ones
Fact: Homemade or “natural” sunscreens often lack adequate protection and regulation. Use FDA-approved sunscreens that offer broad-spectrum protection, as this is your best defence against harmful UV rays.
Remember, effective sun protection not only prevents skin damage but also plays a significant role in minimising the risk of skin cancers. Make sunscreen a non-negotiable part of your daily skincare regimen to maintain healthy, radiant skin for years to come.
