Summer Skincare Guide: How Often Should You Reapply Sunscreen?

As the summer sun beats down, safeguarding your skin becomes paramount. Learn how often you should reapply sunscreen to stay protected.

Summer brings sun, fun, and the need for vigilant skincare. Sunscreen is your shield against harmful UV radiation, but its effectiveness wanes throughout the day. According to Noida-based Aesthetic Consultant & Physician, Dr. Saru Singh, factors like sweat, water, and friction compromise sunscreen efficacy, necessitating regular reapplication. Dermatologists stress the importance of sunscreen reapplication to prevent sunburn, premature aging, and skin cancer.

Dr. Saru suggests reapplying sunscreen every two hours, or more frequently if sweating heavily or engaging in water activities. It’s crucial to use an adequate amount, covering your entire body and ensuring no area is overlooked. Gently apply sunscreen to avoid disrupting the existing layer. Opt for a broad-spectrum sunscreen with an SPF of 30 or higher, and choose water-resistant formulas if needed. Adjust the reapplication frequency based on environmental factors like intense sunlight, reflective surfaces, or high altitudes. Developing a consistent habit of sunscreen reapplication, especially during peak sun hours, is essential for long-term skin health.

Dr. Kashish Kalra, a dermatologist and founder of Dr. Kalra Skin Clinic, stresses the importance of sunscreen reapplication. “Sunscreen isn’t a one-and-done deal,” he explains. “Its protective ingredients start to break down upon exposure to sunlight, sweat, and water. Regular reapplication is crucial for maintaining its sun protection factor (SPF). Along with reapplication, using a sufficient quantity of sunscreen is equally important.” Dr. Kashish recommends aiming for about 2mg of sunscreen per square centimeter of skin, roughly equivalent to half a teaspoon for your face and neck.

When selecting sunscreen, Dr. Kashish advises looking for the Boots Star Rating, especially if you’re concerned about UVA protection. A Boots Star Rating of at least PA+++ indicates sufficient protection against UVA rays, which are linked to premature aging and skin damage.

In summary, the reapplication of sunscreen, along with using a sufficient quantity and choosing the right sunscreen with adequate UVA protection, is essential for maintaining healthy, youthful skin throughout the summer and beyond.
