How to Choose a Sunblock
With the summer season comes the need to protect our skin from the harsh sun rays. Choosing the right sunblock can be confusing with all the options available in the market. But worry not! Here’s a comprehensive guide to help you choose the perfect sunblock for your needs.
1. Understand SPF Ratings
The Sun Protection Factor (SPF) indicates how long your skin will be protected from UVB rays, which are responsible for sunburns. The higher the SPF, the more protection you get against UVB rays. However, no sunscreen can block 100% of UVB rays. An SPF of 30 provides approximately 97% protection, while an SPF of 50 offers around 98% protection – this is only marginally better than SPF 30. Therefore, experts recommend using an SPF between 30 and 50 for daily use.
2. Look for Broad-Spectrum Protection
While SPF measures protection against UVB rays, it’s essential to have protection against UVA rays as well. UVA rays penetrate deeply into the skin and contribute to premature skin aging and the development of skin cancer. To ensure that you’re protected from both types of harmful radiation, look for sunscreens labeled as “broad-spectrum”.
3. Consider Your Skin Type
Different skin types require different types of sunscreen, so identify and understand your skin type before choosing sunblock:
– Normal or combination skin: You can use any type of sunscreen that feels comfortable on your face.
– Oily or acne-prone skin: Opt for oil-free or non-comedogenic sunscreen formulations.
– Sensitive skin: Choose a mineral-based sunscreen since they are less likely to cause irritations; avoid fragrances and allergens as well.
– Dry skin: Look for sunscreens with added moisturizers or choose a moisturizer with built-in SPF.
4. Check for Water Resistance
A water-resistant sunblock is essential if you plan to swim, sweat, or participate in physical activities that might cause sunscreen to wear off quickly. While no sunscreen is completely waterproof, water-resistant products should remain effective for up to 40 or 80 minutes when submerged in water, as long as proper application and reapplication recommendations are followed.
5. Choose the Right Formulation
Sunscreen comes in various forms: lotions, creams, sprays, and sticks. Choose the one that suits your preferences and ensures thorough application:
– Lotions and creams work best for face application.
– Sprays are convenient for quickly covering larger body areas but be careful not to inhale them.
– Sticks are suitable for small areas or hard-to-reach spots like your ears.
6. Check the Expiration Date
Sunscreens usually have a shelf life of up to three years. However, if you have an old product lying around, make sure to check the expiration date before using it. An expired sunscreen may provide lower levels of protection due to degraded active ingredients.
To sum up, finding the right sunblock involves understanding SPF ratings, looking for broad-spectrum protection that suits your skin type, considering water resistance and formulation preferences. Moreover, always remember to apply generously and reapply every two hours (or after swimming or excessive sweating) for optimal sun protection.
