Sunscreen Factors Explained: Choosing the Right SPF for Your Skin
Article:Got the Sunburn Blues? Navigating Sunscreen Picks for All Skin Types and Activities
Anyone stepping foot into a store's sunscreen aisle may feel a bit overwhelmed. Faced with creams, gels, sprays, SPFs varying from low to high, and options geared for kids or adults, finding the perfect sunscreen to protect your skin from UV radiation can be tricky. Two experts answer common questions to help you make an informed decision about sunscreen products that cater to your unique needs.
1. So, what's the deal with SPF?
Every sunscreen has a sun protection factor (SPF). Ranging from 6 up to 50+, the higher the SPF, the longer the cream or spray shields your skin from sunburn and damage caused by UV rays.
To determine the duration of protection, multiply the SPF by your natural protection time based on your skin type. For example, a fair-skinned person with blonde or red hair may only last a few minutes in the sun without burning, but by using a sunscreen with a high SPF, they could theoretically bask in the sun for up to 500 minutes.
However, it's essential to remember that sunscreen does not offer complete protection from UV radiation. Regardless of SPF, it's recommended that sunscreen application should not exceed 60 percent of the theoretical protection time, as stated by the Federal Office for Radiation Protection (BfS).
2. What sunscreen's right for me?
In addition to your skin type and the resulting SPF, other factors such as skin texture and preferred product type play an important role in finding the ideal sunscreen. Preferences matter, especially if you prefer run-resistant sunscreens for athletic activities or lighter, quick-absorbing formulas suitable for dryer skin.
Ultimately, selecting a sunscreen that works well and is enjoyable to use is crucial because you'll be more inclined to apply it regularly.
3. When's sun protection most vital?
A myriad of factors influences the UV radiation levels in diverse conditions, such as season, latitude, and time of day. Remarkably, even on cloudy days, UV radiation may be more potent than on a clear one.
The UV index, which can range between 1 and 11+, serves as a helpful guide. You can find the index in common weather apps. The BfS advises protecting your eyes and skin when the UV index is above 3. In particularly high readings of 8, it's advisable to avoid the strongest midday hours.
4. Applying sunscreen the smart way
To ensure optimal protection, cover all exposed body parts. Forgettable areas often missed include ears, lips, hands, neck, and the transitions between skin and clothing items. Those with less or no hair should be mindful of applying sunscreen or wearing a head covering on the scalp. Sunscreens can also protect the spaces between toes and fingers.
To work effectively, your skin should be hydrated before the application of sunscreen over a moisturizer without SPF. In this way, the sunscreen will adhere better to your skin.
5. How much sunscreen needed?
People often use insufficient amounts of sunscreen. Aim for 2 milligrams of sunscreen per square centimeter of skin to achieve optimum protection, roughly equivalent to one-fifth of a 200-milliliter bottle for an adult's entire body.
Using a rule of thumb, apply two finger lengths of sunscreen (from the knuckle to the tip) per body region, so for one leg, one arm, or the face.
Ideally, apply sunscreen 30 minutes before going outside and reapply as necessary. Twice daily is sufficient for basic protection, yet frequent reapplication is advised for intense sun or sweating.
6. Sunscreen for kids
Unlike adults, babies and young children lack their own skin protection. Special care must be taken with little ones. Opt for sunscreen formulated for children, as they may avoid fragrances and preservatives that could aggravate the risk of allergies.
Since children's skin is sensitive to the sun, a high SPF is essential for them. Additionally, shield their delicate eyes with sunglasses and consider using a hat for extra protection.
7. Sunscreen longevity
Sunscreens in perfect condition, unopened and stored indoors, are safe to use without fear of expiration. However, once opened, most sunscreens have a shelf life of around 12 months.
Check the product packaging for an open-jar symbol with a number that indicates the month your sunscreen was opened. If the product smells off, separates into oil and water, or maintains a rancid scent, throw it away. Also, discard sunscreen if it's been exposed to extreme heat.
