As the sun's rays beat down, many of us reach for sunblock or sunscreen to protect our skin. But what's the difference between the two, and how do they affect our skin?
Sunblock and sunscreen are two different types of sun-shielding products that work in varying ways. Sunscreen filters the harmful UV rays affecting the skin, while sunblock works to reflect the sun's rays away from the skin.
Sunblock, often containing zinc oxide or titanium dioxide forms a strong physical barrier that reflects and scatters UV rays on the skin. On the other hand, sunscreen contains chemicals that absorb UV radiation, converting it into heat and then releasing it from the body. These products are powerful at safeguarding the skin from sunburn and averting wrinkles.
Both sunblock and sunscreen can help prevent sunburn, premature ageing, and skin cancer. However, choosing the right product for your needs and skin type is essential. Sunblocks are often thicker and may leave a white cast on the skin, while sunscreens are lighter and easier to apply.
Sunblock
Sunblock contains physical blockers such as zinc oxide or titanium dioxide. These minerals work on the top layer of the skin and reflect UV rays away from attacking the skin. Sunblocks are often thicker and can leave a white cast on the skin.
Sunscreen
Sunscreen contains chemical filters that absorb UV radiation and change it into heat, which is then released from the body. Sunscreens are lighter in texture and effortless to use than sunblocks.
Both sunblock and sunscreen can protect the skin from sunburn, premature ageing, and skin cancer, but they work in slightly different ways. It's essential to choose a broad-spectrum product that guards against UVA and UVB rays and reuse it regularly for maximum effectiveness.
How to Choose the Right Sun Guard?
Both products are incredible forms of sun protection. The American Academy Of Dermatology (AAD) doesn't recommend using one product over the other. Remember to choose one product that delivers:
A broad range of coverage against UVA and UVB rays
SPF 30 or greater
Waterproof
A wide spectrum of sunblocks and sunscreens will avert tanning and premature ageing as well as sunburn.
Also, it is important to apply sun protection cream correctly. Sunscreen or sunblock will only guard the skin when it's properly used.
Research has shown that sunscreens must be used correctly to deliver the protection the products are supposed to offer.
Effective Tips To Follow
Choose A Broad-Spectrum Product: Look for a sunblock or sunscreen that safeguards the skin against both UVA and UVB rays.
Use The Right Amount: Apply a generous amount of sunblock or sunscreen to all exposed skin at least 15 minutes before going outside.
Reapply Regularly: Reapply sunblock or sunscreen every two hours or immediately after swimming, sweating, or towel-drying.
Cover Up: Always cover yourself with protective clothing, such as a wide hat and sunglasses, and seek shade during peak sun hours.
Check The Expiration Date: Sunblock and sunscreen lose their effectiveness over the period, so ensure to check the expiration date before using products.
By understanding the differences between sunblock and sunscreen and following these measures, you can effectively shield your skin from the sun's harmful rays and enjoy staying outdoors safely.
