Skin protection: Debunking common sunscreen myths

Myth 1: You only need sunscreen on sunny days

Fact: UV rays can penetrate clouds, so your skin is at risk even on overcast days. The Hong Kong Observatory notes that up to 15% of UV radiation can be reflected on sandy beaches, making sunscreen application especially essential on beach days. 

Myth 2: People with darker skin don't need sunscreen

Fact: While melanin provides some natural protection, individuals with darker skin tones are still susceptible to sun damage, including premature aging and hyperpigmentation. Sunscreen is crucial for everyone, regardless of skin color.

Myth 3: A high SPF means you can stay in the sun longer

Fact: Higher SPF numbers offer more protection, but they don't grant you a pass to spend excessive time in the sun. Regardless of the SPF, sunscreen should be reapplied every two hours, or more frequently if swimming or sweating.

Myth 4: Makeup with SPF is sufficient sun protection

Fact: While makeup with SPF offers some protection, it's usually not enough. Most people don't apply makeup thickly or evenly enough to achieve the stated SPF level. For adequate protection, use a broad-spectrum sunscreen under your makeup.

Myth 5: Sunscreen is only necessary in summer

Fact: Sun protection is a year-round necessity. UV rays can cause damage in any season, and reflective surfaces like snow can intensify their effects. 

Myth 6: Sunscreen is harmful to the environment

Fact: While some concerns have been raised about certain sunscreen ingredients and coral reefs, the primary causes of reef degradation are pollution, climate change, and overfishing. Many reef-safe sunscreen options are available for environmentally conscious consumers.

To ensure optimal skin protection:

1. Choose a broad-spectrum sunscreen with an SPF of 30 or above.
2. Apply sunscreen generously 15 minutes before sun exposure.
3. Reapply every two hours – and do so more frequently when swimming or sweating.
4. Use sunscreen daily, even on cloudy days or in winter.
5. Complement sunscreen use with protective clothing, hats and sunglasses.

By dispelling these myths and adopting proper sun protection habits, you can enjoy outdoor activities while keeping your skin healthy and youthful. Remember, protecting your skin is a lifelong commitment that goes beyond just preventing sunburns – it's about maintaining overall skin health and preserving your skin's appearance for years to come.
