The Science of Sunscreen: How to Choose the Right SPF for Your Skin

    • July 15, 2024

    Skin health is the foundation of beauty. As the summer sun beams down on us there is no better time than the present to understand the science of sunscreen and how choosing the right SPF can make a difference for your skin. 

    In this blog, we’ll review the ins and outs of SPF selection, the importance of broad-spectrum sunscreen, and provide guidelines to ensure you protect your skin for years of beauty to come.

    Understanding Sunscreen Science

    Sunscreen is a product that is scientifically designed to shield your skin from the harmful effects of ultraviolet (UV) radiation. UV radiation is divided into UVA and UVB rays, both of which can cause skin damage. While UVA rays penetrate deeply into the skin, leading to premature aging and wrinkles, UVB rays are responsible for sunburn and can directly damage DNA, increasing the risk of skin cancer.

    Consistent use of sunscreen helps prevent sunburn, reduces the risk of skin cancer, and prevents premature aging so incorporating sunscreen into your daily skincare routine should be the first step toward maintaining skin health. For those with specific skin concerns, such as hyperpigmentation or sensitive skin, choosing the right sunscreen can make a significant difference in managing these conditions.

    What is SPF?

    SPF, or Sun Protection Factor, measures a sunscreen’s ability to protect your skin from UVB rays. The number indicates how long you can stay in the sun without getting sunburned compared to if you were not wearing any sunscreen. 

    For instance, if you use SPF 30, it theoretically allows you to stay in the sun 30 times longer without burning than if you were unprotected. However, SPF does not measure UVA protection, making it essential to look for broad-spectrum sunscreens if you want to be fully protected.

    Your skin type plays a significant role in determining the appropriate SPF level. Fair skin, which burns easily, requires higher SPF for adequate protection, while darker skin, which is less prone to burning, may use a lower SPF. However, contrary to popular belief all skin types need protection from UV damage.

    SPF Guidelines: Finding the Right Balance

    • Daily Use: For everyday activities, such as commuting or brief outdoor activities, an SPF of 15 to 30 is typically sufficient.
    • Extended Outdoor Activities: For prolonged outdoor exposure, such as hiking, beach days, or sports, an SPF of 30 to 50+ is recommended.
    • Sensitive Areas: Pay special attention to areas like the face, neck, and hands. Using a higher SPF in these areas can help prevent visible signs of aging.

    Proper Sunscreen Application

    So you’ve picked out the SPF you need in your sunscreen but how can you make sure it’s effective? When it comes to making sure your skin stays wrinkle and burn free there are a few tips you should keep in mind! 

    1. Apply Generously: Use about one ounce (a shot glass full) to cover your entire body. Don’t skimp on coverage, as inadequate application can significantly reduce protection.
    2. Reapply Regularly: Sunscreen should be reapplied every two hours, or immediately after swimming, sweating, or towel drying.
    3. Don’t Miss Spots: Pay attention to commonly missed areas such as the ears, back of the neck, and tops of the feet.
