Many individuals hold the misconception that sunscreen is only necessary for beach outings or summer holidays. Renowned skincare expert Dr. Karuna Malhotra asserts that this notion is one of the prevalent skincare blunders. Sunscreen should be used daily, not just on sunny days, to protect the skin from harmful solar rays. Its continuous use aids in preventing early aging, skin burns, wrinkles, and even skin cancer.

Despite its significance, numerous myths surrounding sunscreen lead individuals to forego its daily application. To set the record straight, cosmetologist and aesthetic physician Dr. Karuna Malhotra, founder of the Cosmetic Skin and Homeo Clinic, clarifies six of the most commonly held misconceptions.

Myth 1: A higher SPF offers better protection

Fact: Many assume that a higher SPF signifies superior sunscreen. Dr. Malhotra emphasizes that SPF only gauges UVB ray defense, which causes sunburn, without accounting for UVA rays linked to skin damage and aging. “A broad-spectrum sunscreen that shields against both UVA and UVB rays is paramount,” she advises.

Myth 2: Dark-skinned individuals don’t need sunscreen

Fact: There’s a belief that individuals with darker skin tones require no SPF due to the protective properties of melanin. However, Dr. Malhotra cautions that this is misleading. “Melanin cannot effectively block UVA rays that induce wrinkles and early aging,” she explains. Full-spectrum sunscreen remains essential for darker skin tones to prevent long-term harm.

Myth 3: Sunscreen can be skipped on cloudy days

Fact: Up to 80% of UV rays penetrate the skin even on overcast days. “Sun damage can occur during cloudy or rainy conditions as well; therefore, daily sunscreen usage is critical, regardless of the weather,” affirms Dr. Malhotra.

Myth 4: A single application of sunscreen lasts all day

Fact: Sunscreen protection doesn’t last indefinitely. “It deteriorates in sunlight,” states Dr. Malhotra. Reapplying every 2–4 hours is vital, especially when sweating or engaging in outdoor activities.

Myth 5: Sunscreen is waterproof

Fact: “No sunscreen is completely waterproof,” she clarifies. While some may be labeled as “water-resistant,” they still lose efficacy after swimming or sweating. Always reapply after exposure to water, she advises, adding that sunscreen should be applied 10–15 minutes before entering the water to enhance effectiveness.

Myth 6: Sunscreen isn’t necessary during winter

Fact: Cold weather may seem safe, yet UV rays remain potent. Dr. Malhotra cautions, “Even in winter, 80% of UV rays can infiltrate clouds and fog.” This exposure can lead to tanning, pigmentation, and premature aging. Snow and glass can amplify sunlight reflection, escalating skin exposure, making sunscreen an all-year-round necessity.

The Ultimate Truth: Sunscreen is vital for your skin

Awareness of sunscreen truths enables better skin protection. Dr. Malhotra underscores that sunscreen isn’t a standalone shield; additional precautions, such as wearing protective clothing and seeking shade, are essential, especially between 10 a.m. and 4 p.m.

In conclusion, sunscreen is more than just a cosmetic; it serves as a daily defense for your skin. Whether in summer or winter, sunny or cloudy, daily application of sunscreen is the simplest method to maintain healthy and youthful skin for years to come.
